    Abstract

    In this study, the mechanism of fragmentation including void formation in an injectable calcium-phosphate cement of paste-like artificial bone grafting material, is clarified from the point of view of mathematical modeling. Instead of modeling from physical laws or chemical reactions, phenomenological modeling is used, and three experiments are performed to build the model. We then successfully use the results in terms of the equations and necessary assumptions to construct a simple mathematical model. Our proposed model is based on the mathematically well-known Allen-Cahn type equation. The state of the paste is used as an unknown function. After scaling according to the appropriate nondimensionalization, numerical simulations are performed. The numerical results represent the setting behavior of the paste, which is difficult to observe experimentally. The integration of mathematical and experimental results provides deep insight into the mechanism of non-fragmentation property of an injectable calcium-phosphate cement.

  • Preferred Orientation of Hydroxyapatite Ceramics Along the c-Axis Promotes Osteoblast Differentiation

    Kitaru Suzuki, Masaki Tamazawa, Erika Onuma, Michiyo Honda, Mamoru Aizawa

    Hydroxyapatite (HAp) is similar to the main inorganic components of bone and tooth enamel. Furthermore, it possesses biocompatibility, making it suitable for clinical use in artificial bones. This study aimed to verify whether the preferred orientation of HAp influences osteogenesis. Using the templated grain growth method, we successfully fabricated HAp ceramics with a preferred orientation to m (a)-planes (aHAp) and examined the effects of this orientation on bone differentiation. Osteosarcoma-derived osteoblasts (MG-63) were cultured on aHAp and HAp ceramics made from commercially available powder (iHAp). Electron backscatter diffraction analysis revealed the crystal orientation distribution of HAp ceramics and the numerous exposed a-planes of aHAp. The MG-63 cultured on aHAp exhibited significantly higher alkaline phosphatase activity, a marker of early bone differentiation, compared to iHAp. Furthermore, the two-dimensional electrophoresis results indicated that the expressed proteins differed between aHAp and iHAp. These results indicate that controlling HAp’s crystal structure may promote the osteogenic potential of osteoblasts. In this study, we propose that the a-plane of HAp promotes bone differentiation during the early stages, presenting a promising approach for novel biomaterials, such as high-performance artificial bones.

    We have previously reported that a novel bioresorbable self-setting injectable bone paste composed of hydroxyapatite/collagen bone-like nanocomposite (HAp/Col) and (3-glycidoxypropyl)trimethoxysilane (GPTMS) was successfully prepared and was replaced with new bone within 3 months of implantation in defects created in porcine tibia. In this study, the HAp/Col-GPTMS paste was implanted into bone defects in rat tibiae to investigate the initial kinetics and bone tissue response. Even though more than 35% of GPTMS molecules should be eluted rapidly from directly injected pastes according to previously reported cell culture tests, in this study, energy-dispersive X-ray spectrometry did not detect Si (GPTMS) deposition in tissues surrounding the paste at 1 day postimplantation. Further, no abnormal inflammatory responses were observed in the surrounding tissues over the test period for both directly injected and prehardened pastes. Companying these observations with the results of the previous animal test (in which the paste was fully resorbed and was substituted with new bone), the eluted GPTMS resolved in no harm in vivo from the initial to final (completely resorbed) stages. Material resorption rates calculated from X-ray microcomputed tomography (μ-CT) images decreased with increasing in GPTMS concentration. Histological observations indicated that tartrate-resistant acid phosphatase (TRAP) active cells, (assumed to be osteoclasts), exist on the periphery of pastes. This result suggested that the paste was resorbed by osteoclasts in the same way as the HAp/Col. Since a good correlation was observed between TRAP active areas in histological sections and material resorption rate calculated from μ-CT, the TRAP activity coverage ratio offers the possibility to estimate the osteoclastic resorption ratio of materials, which are replaced with bone via bone remodeling process.

    Ex vivo tissue engineering is an effective therapeutic approach for the treatment of severe cartilage diseases that require tissue replenishment or replacement. This strategy demands scaffolds that are durable enough for long-term cell culture to form artificial tissue. Additionally, such scaffolds must be biocompatible to prevent the transplanted matrix from taking a toll on the patient's body. From the viewpoint of structure and bio-absorbability, a β-tricalcium phosphate (β-TCP) fiber scaffold (βTFS) is expected to serve as a good scaffold for tissue engineering. However, the fragility and high solubility of β-TCP fibers make this matrix unsuitable for long-term cell culture. To solve this problem, we developed an alginate-coated β-TCP fiber scaffold (βTFS-Alg). To assess cell proliferation and differentiation in the presence of βTFS-Alg, we characterized ATDC5 cells, a chondrocyte-like cell line, when grown in this matrix. We found that alginate coated the surface of βTFS fiber and suppressed the elution of Ca2+ from β-TCP fibers. Due to the decreased solubility of βTFS-Alg compared with β-TCP, the former provided an improved scaffold for long-term cell culture. Additionally, we observed superior cell proliferation and upregulation of chondrogenesis marker genes in ATDC5 cells cultured in βTFS-Alg. These results suggest that βTFS-Alg is suitable for application in tissue culture.

    Protein adsorption is essential for determining material biocompatibility and promoting adherent cell growth. In this study, we focused on the a-plane structure of hydroxyapatite (HAp). This a-plane structure closely resembles the crystal plane where apatite is exposed in long bones. We conducted protein adsorption experiments using HAp ceramics with a preferred orientation to a-planes (aHAp), employing bovine serum albumin (BSA), lysozyme, and fetal bovine serum (FBS) as protein models to mimic the in vivo environment. Higher zeta potential and contact angle values were found in aHAp than in HAp ceramics fabricated from commercial HAp powder (iHAp). Bradford-quantified protein adsorption revealed BSA adsorption of 212 ng·mm−2 in aHAp and 28.4 ng mm−2 in iHAp. Furthermore, the Bradford-quantified protein adsorption values for FBS were 2.07 μg mm−2 in aHAp and 1.28 µg mm−2 in iHAp. Two-dimensional electrophoresis (2D-PAGE) showed a higher number of protein-derived major spots in aHAp (37 spots) than in iHAp (12 spots). Mass spectrometry analysis of the resulting 2D-PAGE gels revealed proteins adsorbed on aHAp, including secreted frizzled-related protein 3 and vitamin K epoxide reductase complex 1, which are involved in cellular bone differentiation. Overall, these proteins are expected to promote bone differentiation, representing a characteristic property of aHAp.

    Calcium phosphates are key biomaterials in dental treatment and bone regeneration. Biomaterials must exhibit antibacterial properties to prevent microbial infection in implantation frameworks. Previously, we developed various types of calcium phosphate powders (amorphous calcium phosphate, octacalcium phosphate (OCP), dicalcium phosphate anhydrate, and hydroxyapatite) with adsorbed protamine (which is a protein with antibacterial property) and confirmed their antibacterial property. In this study, as foundational research for the development of novel oral care materials, we synthesized calcium phosphate composite powders from three starting materials: i) OCP, which intercalates organic compounds, ii) protamine, which has antibacterial properties, and iii) F- ion, which promotes the formation of apatite crystals. Through investigating the preparation concentration of the F- ions and their loading into OCP, it was found that more F- ion could be loaded at higher concentrations regardless of the loading method. It was also observed that the higher the preparation concentration, the more the OCP converted to fluorapatite. The synthesized calcium phosphate composite powders were evaluated for biocompatibility through proliferation of MG-63 cells, with none of the powders exhibiting any growth inhibition. Antimicrobial tests showed that the calcium phosphate composite powders synthesized with protamine and F- ion by precipitation had enhanced antimicrobial properties than those synthesized by protamine adsorption. Thus, the calcium phosphate composite powder prepared from OCP, protamine, and F- ion forms the basis for promising antimicrobial biomaterials. Graphical abstract.

    With the limitation of autografts, the development of alternative treatments for bone diseases to alleviate autograft-related complications is highly demanded. In this study, a tissue-engineered bone was formed by culturing rat bone marrow cells (RBMCs) onto porous apatite-fiber scaffolds (AFSs) with three-dimensional (3D) interconnected pores using a radial-flow bioreactor (RFB). Using the optimized flow rate, the effect of different culturing periods on the development of tissue-engineered bone was investigated. The 3D cell culture using RFB was performed for 0, 1 or 2 weeks in a standard medium followed by 0, 1 or 2 weeks in a differentiation medium. Osteoblast differentiation in the tissue-engineered bone was examined by alkaline phosphatase (ALP) and osteocalcin (OC) assays. Furthermore, the tissue-engineered bone was histologically examined by hematoxylin and eosin and alizarin red S stains. We found that the ALP activity and OC content of calcified cells tended to increase with the culture period, and the differentiation of tissue-engineered bone could be controlled by varying the culture period. In addition, the employment of RFB and AFSs provided a favorable 3D environment for cell growth and differentiation. Overall, these results provide valuable insights into the design of tissue-engineered bone for clinical applications.

    Calcium carbonate is used as bone-filling material due to its good biocompatibility, bioactivity, and bioabsorbability, but the prevalence of infectious complications associated with calcium carbonate has created a persisting challenge in the treatment of bone defect. Therefore, this greatly necessitate the need to endow calcium carbonate with antibacterial properties. In this study, calcium carbonate powders loaded with silver nanoparticles (Ag-CaCO3) were prepared in attempt to serve as a novel antibacterial inorganic filler material. This objective was achieved using ultrasonic spray-pyrolysis (USSP) route to produce Ag-CaCO3 with 1, 5 and 10 mol% silver. The size of silver nanoparticles on CaCO3 microspheres could be regulated by adjusting silver concentration to facilitate effective release of Ag+ ions. This was demonstrated in Ag-CaCO3 (1), where the lowest silver content at 1 mol% achieved the highest Ag+ ions release over 28 days. This in turn gave rise to effective antibacterial efficiency against Staphylococcus aureus and Escherichia coli. Furthermore, CaCO3 (1) could also support osteoblast-like cells (MG-63) at a cell viability of 80%. Overall, this work extends the capabilities in employing USSP to produce inorganic filler materials with sustained antibacterial properties, bringing one step closer to the development of antibacterial products.

  • Zoledronic Acid-Loaded β-TCP Inhibits Tumor Proliferation and Osteoclast Activation: Development of a Functional Bone Substitute for an Efficient Osteosarcoma Treatment. International journal

    Osteosarcoma has a poor survival rate due to relapse and metastasis. Zoledronic acid (ZOL), an anti-resorptive and anti-tumor agent, is used for treating osteosarcoma. Delivery of ZOL to the target region is difficult due to its high binding affinity to bone minerals. This study developed a novel treatment for osteosarcoma by delivering ZOL to the target region locally and sustainably. In this study, we fabricated a novel bone substitute by loading ZOL on β-tricalcium phosphate (β-TCP). The ZOL-loaded β-TCP (ZOL/β-TCP) would be expected to express the inhibitory effects via both bound-ZOL (bound to β-TCP) and free-ZOL (release from ZOL/β-TCP). To explore the ability to release ZOL from the ZOL/β-TCP, the amount of released ZOL was measured. The released profile indicates that a small amount of ZOL was released, and most of it remained on the β-TCP. Our data showed that ZOL/β-TCP could successfully express the effects of ZOL via both bound-ZOL and free-ZOL. In addition, we examined the biological effects of bound/free-ZOL using osteosarcoma and osteoclasts (target cells). The results showed that two states of ZOL (bound/free) inhibit target cell activities. As a result, ZOL/β-TCP is a promising candidate for application as a novel bone substitute.

    To prevent infections associated with medical implants, various antimicrobial silver-coated implant materials have been developed. However, these materials do not always provide consistent antibacterial effects in vivo despite having dramatic antibacterial effects in vitro, probably because the antibacterial effects involve silver-ion-mediated reactive oxygen species generation. Additionally, the silver application process often requires extremely high temperatures, which damage non-metal implant materials. We recently developed a bacteria-resistant coating consisting of hydroxyapatite film on which ionic silver is immobilized via inositol hexaphosphate chelation, using a series of immersion and drying steps performed at low heat. Here we applied this coating to a polymer, polyetheretherketone (PEEK), and analyzed the properties and antibacterial activity of the coated polymer in vitro and in vivo. The ionic silver coating demonstrated significant bactericidal activity and prevented bacterial biofilm formation in vitro. Bio-imaging of a soft tissue infection mouse model in which a silver-coated PEEK plate was implanted revealed a dramatic absence of bacterial signals 10 days after inoculation. These animals also showed a strong reduction in histological features of infection, compared to the control animals. This innovative coating can be applied to complex structures for clinical use, and could prevent infections associated with a variety of plastic implants.

    Bacterial infection of biomaterials is a serious problem in the field of medical devices. It is urgently necessary to develop new biomaterials with bactericidal activity. Antimicrobial peptides and proteins (AMPs), alternative antibacterial agents, are expected to overcome the bacterial resistance. The aim of this study was to develop a new intelligent material in bone tissue engineering based on protamine-loaded hydroxyapatite (protamine/HAp) that uses AMPs rather than antibiotics. It was found that the adsorption of protamine to HAp followed the Langmuir adsorption model and was due to electrostatic and/or hydrophobic interactions. In vitro bacterial adhesion and growth on protamine/HAp was inhibited in a protamine dose-dependent manner. Adherent bacteria exhibited an aberrant morphology for high dosages of protamine/HAp, resulting in the formation of large aggregates and disintegration of the membrane. The released protamine from protamine/HAp also prevented the growth of planktonic bacteria in vitro. However, a high dosage of protamine from powders at loading concentrations over 1000 μg·mL-1 induced a cytotoxic effect in vitro, although those exhibited no apparent cytotoxicity in vivo. These data revealed that protamine/HAp (less than 1000 μg·mL-1) had both antimicrobial activity and biocompatibility and can be applied for bone substitutes in orthopedic fields.

    Bacterial adhesion to the calcium phosphate surface is a serious problem in surgery. To prevent bacterial infection, the development of calcium-phosphate cements (CPCs) with bactericidal properties is indispensable. The aim of this study was to fabricate antibacterial CPCs and evaluate their biological properties. Silver-containing tricalcium phosphate (Ag-TCP) microspheres consisting of α/β-TCP phases were synthesized by an ultrasonic spray-pyrolysis technique. The powders prepared were mixed with the setting liquid to fabricate the CPCs. The resulting cements consisting of β-TCP and hydroxyapatite had a porous structure and wash-out resistance. Additionally, silver and calcium ions could be released into the culture medium from Ag-TCP cements for a long time accompanied by the dissolution of TCP. These data showed the bioresorbability of the Ag-TCP cement. In vitro antibacterial evaluation demonstrated that both released and immobilized silver suppressed the growth of bacteria and prevented bacterial adhesion to the surface of CPCs. Furthermore, histological evaluation by implantation of Ag-TCP cements into rabbit tibiae exhibited abundant bone apposition on the cement without inflammatory responses. These results showed that Ag-TCP cement has a good antibacterial property and good biocompatibility. The present Ag-TCP cements are promising for bone tissue engineering and may be used as antibacterial biomaterials.

    Protamine is an antimicrobial peptide extracted from fish. In this study, we loaded protamine onto dicalcium phosphate anhydride (DCPA), a dental material. Protamine was loaded by stirring DCPA into a protamine solution. To explore the antimicrobial activity of the materials, we cultivated Streptococcus mutans on fabricated discs for 24 h. When S. mutans was cultivated on the discs under no sucrose conditions, the loaded protamine was not released, and the ratio of dead bacteria increased on the surface of P (125) DCPA (half of the saturated level of protamine (125 ppm protamine) was loaded). Aside from P (500) DCPA (saturated level of protamine was loaded), some protamine was released, and the number of planktonic bacteria in the supernatant decreased. Using medium containing 1% sucrose, the release of protamine was promoted from P (125) DCPA due to lowered pH. However, lowering of the pH decreased the antimicrobial activity of protamine. On the other hand, P (500) DCPA released protamine before the pH was lowered, and biofilm formation was inhibited. The loaded protamine expressed antimicrobial activity, both on the surface of the materials and in the surrounding environment. The interaction of loaded protamine with calcium phosphates could promote the application of protamine in the dental field.

    In bone regeneration, there are some important cellular biological processes, such as mineralization, cell organization, and differentiation. In particular, vascularization into regenerative tissues is a key step for the survival of cells and tissues. In this study, to fabricate biomimetic-engineered bone, including vascular networks, we focused on connective tissue growth factor (CTGF), a multifunctional protein which could regulate the extracellular matrix remodeling. By combination with CTGF and hydroxyapatite (HAp) ceramics (2D) or apatite-fiber scaffold (AFS, 3D), we have fabricated bioactive materials. The CTGF-loaded HAp ceramics could enhance the cellular attachment through interaction with integrin and promote actin cytoskeletal reorganization. CTGF-loaded HAp also enhanced the differentiation of osteoblasts by integrin-mediated activation of the signaling pathway. Under co-culture conditions, both osteoblasts and endothelial cells in the CTGF-loaded AFS were stimulated by CTGF, and each cell could penetrate the central region of the scaffold in vitro and in vivo. Direct cell-cell interaction would also improve the functionality of cells in bone formation. These results suggest that coupling between effective optimized scaffold and CTGF with multifunction could provide better mimicking natural bone by stimulation of angiogenesis.

    Moldable and injectable calcium-phosphate cements (CPCs) are material candidates for bone replacement applications. In the present study, we examined the effectiveness of sodium alginate and sodium citrate additives to the liquid phase of CPC, in improving its handling property as well as mechanical strength. The use of these additives enhanced the handling property significantly, in terms of consistency as compared to CPC without additives due to the liquefying effect caused by the adsorption of citrate ions on the cement particles. Sodium alginate and sodium citrate were added to CPC, which was set by the chelate-bonding capability of inositol phosphate, and was composed of mainly α-tricalcium phosphate (α-TCP) phase (>90%). The compressive strength of the CPC containing sodium alginate and sodium citrate was 3.4 ± 0.3 MPa, which was significantly higher than cement without additives. Furthermore, this cement exhibited favorable osteoconductivity and bioresorbability, and remained the α-TCP phase after 4-week implantation in a pig tibiae model. These results suggested that the cement is a potential candidate as a bioresorbable paste-like artificial bone. © 2017 Wiley Periodicals, Inc.

    Biological apatite presented in bone and teeth of mammals contains various ions, such as Na<SUP>+</SUP>, K<SUP>+</SUP>, Mg<SUP>2+</SUP>, F<SUP>-</SUP> and CO<SUB>3</SUB><SUP>2-</SUP> ions, in trace levels. Substitution of the above ions into hydroxyapatite (HAp) have great effect on the crystallinity, morphology, lattice parameters and stability of the apatite structure. It is known that potassium (K) in the living bone give a tremendous effect to the biomineralization process. Aim of this study is to clarify the influence of substitution of potassium into the HAp structure on the properties of powders and ceramics. In this study, we have fabricated the potassium-substituted hydroxyapatite (KAp) ceramics via an ultrasonic spray-pyrolysis route. Effect of potassium substitution on the phase, chemical composition, morphology and crystal lattice structure of HA was examined. Experimental results showed that the addition of potassium does not significantly affect the crystal phase, particle morphology and particle size. Sintered bodies fabricated from KAp powders were of single phase of HAp, and lattice constants of a-axis and c-axis increased with potassium contents. Substitution of potassium into the HAp lattice formed OH vacancies and caused grain growth.

    We have previously developed a chelate-setting calcium-phosphate cement (CPC) consisting of hydroxyapatite (HAp) powders surface-modified with inositol hexaphosphate (IP6). In the present study, mechanically ball-milled &alpha;-tricalcium phosphate (&alpha;-TCP) powders were added into the IP6-HAp cement in order to enhance its anti-washout capability and mechanical properties. After optimization of the ball-milling conditions, the cement specimens mixed with various amounts of the prepared &alpha;-TCP powders were fabricated. Examinations of their mechanical properties revealed significant increase of compressive strength (CS) with the addition of the &alpha;-TCP powders. Further, it was demonstrated that the specimens of the IP6-HAp powders / the &alpha;-TCP powders mixing ratios of 20/80 and 30/70 [g/g] exhibited comparatively high anti-washout capability. In conclusion, these cements are promising chelate-setting CPCs with enhanced anti-washout capability and mechanical properties.

    &lt;p&gt;Various silver-coated implants have been developed to prevent implant-associated infections, and have shown dramatic effects in vitro. However, the in vivo results have been inconsistent. Recent in vitro studies showed that silver exerts antibacterial activity by mediating the generation of reactive oxygen species in the presence of oxygen. To maintain its antibacterial activity in vivo, the silver should remain in an ionic state and be stably bound to the implant surface. Here, we developed a novel bacteria-resistant hydroxyapatite film in which ionic silver is immobilized via inositol hexaphosphate chelation using a low-heat immersion process. This bacteria-resistant coating demonstrated significant antibacterial activity both in vitro and in vivo. In a murine bioluminescent osteomyelitis model, no bacteria were detectable 21 days after inoculation with S. aureus and placement of this implant. Serum interleukin-6 was elevated in the acute phase in this model, but it was significantly lower in the ionic-silver group than the control group on day 2. Serum C-reactive protein remained significantly higher in the control group than the ionic-silver group on day 14. Because this coa

    本研究では、医療用接着剤の開発を目的として接着強度に対する生体高分子の電荷の影響について検討した。生体高分子には、種々のDS/DD(= COOH/NH2)比を持つカルボキシメチル(CM)化キトサンを用い、このCM-キトサンとクエン酸活性エステル体(CAD)から成る2成分系接着剤について検討した。DS/DDが0.76および0.27の場合は、CAD濃度依存的に接着強度が減少したが、DS/DDが0.52の場合には、5mMで極大値をとりその後減少した。これらの結果から、この接着剤によるコラーゲンケーシング(接着基材)間の接着強度は、基材−接着剤間における二次結合形成が重要であることが示唆された。さらに、DS/DDが0.52のCM-キトサンを用いた場合、臨床で使用されているフィブリン系接着剤と比較して4倍以上の高い強度を示すことが明らかとなった。

    &lt;p&gt;Hydroxyapatite (HAp) is one of components of bone and teeth, and has an osteoconductivity. Thus, the HAp has been used as biomaterials for bone graftings. We have succeeded in development of the novel chelate-setting calcium-phosphate cement (CPC) using pure HAp particles surface-modified with inositol phosphate (IP6). While, biological apatite presented in bone and teeth of mammals contains various ions: Na&lt;inf&gt;+&lt;/inf&gt;, K&lt;inf&gt;+&lt;/inf&gt;, Mg&lt;inf&gt;2+&lt;/inf&gt;, C1&lt;inf&gt;-&lt;/inf&gt;&quot;, F&quot; and C0&lt;inf&gt;3&lt;/inf&gt;&lt;inf&gt;2-&lt;/inf&gt;&quot;, in addition to Ca&lt;inf&gt;2+&lt;/inf&gt; and P0&lt;inf&gt;4&lt;/inf&gt; ions. In this work, in order to create the chelate-setting CPC with enhanced osteoconductivity, the above-mentioned biological apatite powder (hereafter, bone HAp), instead of pure HAp, was used as a starting powder for fabrication of the chelate-setting cement. The biocompatibility of the resulting chelate-setting bone HAp cement (hereafter, IP6-bone HAp cement) was examined using a rabbit&#039;s tibia model. When the living reaction to hard tissue was histologically examined after 4 weeks implantation, we could observe that newly-formed

    &lt;p&gt;Biodegradable α-tricalcium phosphate (α-TCP) cement based on the chelate-setting mechanism of inositol phosphate (IP6) was developed. This paper examined the effect of the milling time of α-TCP powder on the material properties of the cement. In addition, biocompatibility of the result cement in vitro using osteoblasts and in vivo using rabbit models will be studied as well. The α-TCP powders were ballmilled using ZrO&lt;sub&gt;2&lt;/sub&gt; beads in pure water for various durations up to 270 minutes, with a single-phase α-TCP obtained at ballmilling for 120 minutes. The resulting cement was mostly composed of α-TCP phase, and the compressive strength of the cement was 8.5±1.1 MPa, which suggested that the cements set with keeping the crystallite phase of starting cement powder. The cell-culture test indicated that the resulting cements were biocompatible materials. In vivo studies showed that the newly formed bones increased with milling time at a slight distance from the cement specimens and grew mature at 24 weeks, and the surface of the cement was resorbed by tartrate-resistant acid phosphatase-(TRAP-)positive osteoclast-like cells until 24 weeks of implantation.

    A novel tissue consisting of carboxymethylated chitosan (CM-Chitosan) with various degree of substitution of carboxymethylation/degree of deacethylation (DS/DD=COOH/NH2) was developed. In this adhesive, CAD works as a crosslinking reagent of amino groups of CM-Chitosan. The boding time of CAD/CM-Chitosan adhesive reached equilibrium within 5 min when DS/DD of CM-Chitosan was 0.27 and 0.76. While, the bonding time of the CM-Chitosan whose DS/DD was 0.52 rapidly increased within 5 min, however, it took 30 min to become constant level. The bonding strength decreased with increasing CAD concentration when DS/DD of CM-Chitosan was 0.27 and 0.76. On the other hand, bonding strength increased up to CAD concentration of 5 mM and then decreased when DS/DD of CM-Chitosan was 0.52. It was clarified that the resulting bonding strength of CM-Chitosan (DS/DD=0.52) was 4-fold higher than that of fibrin-based adhesive which is commonly used in clinical field.

    The effect of yttrium oxide (Y<SUB>2</SUB>O<SUB>3</SUB>) addition on the sintering of magnesium silicon nitride (MgSiN<SUB>2</SUB>) powder has been examined. The sintering conditions examined in this paper were firing temperature (1400 and 1500°C), firing time (1 to 7 h), and the amount of Y<SUB>2</SUB>O<SUB>3</SUB> (1 to 7 mass%). The phases present, microstructures, flexural strength, and thermal conductivity of the resulting sintered compacts were evaluated using X-ray diffractometry, scanning electron microscopy, flexural testing, and atomic force microscopy. When the MgSiN<SUB>2</SUB> compact without Y<SUB>2</SUB>O<SUB>3</SUB> addition was fired at 1500°C for 1 h or more, it partly decomposed to form α- and β-silicon nitride (Si<SUB>3</SUB>N<SUB>4</SUB>). The formation of α- and β-Si<SUB>3</SUB>N<SUB>4</SUB> upon firing at 1500°C for 3 h could be restricted by the addition of Y<SUB>2</SUB>O<SUB>3</SUB> as a sintering aid; no α- and β-Si<SUB>3</SUB>N<SUB>4</SUB> were detected with increasing Y<SUB>2</SUB>O<SUB>3</SUB> amount up to 3 mass%; further increases in the amount of Y<SUB>2</SUB>O<SUB>3</SUB> up to 7 mass%, however, produced Y2Si<SUB>3</SUB>O3N<SUB>4</SUB>. Maximum relative density (-90%) was attained when a MgSiN<SUB>2</SUB> compact with 3 mass% of Y<SUB>2</SUB>O<SUB>3</SUB> addition was fired at 1500°C for 3 h. The flexural strength of MgSiN<SUB>2</SUB> compacts with 3 to 7 mass% of Y<SUB>2</SUB>O<SUB>3</SUB> addition fired at 1500°C for 3 h attained 160 to 200 MPa. Thermal conductivities of the sintered MgSiN<SUB>2</SUB> compacts with 1 to 7 mass% of Y<SUB>2</SUB>O<SUB>3</SUB> addition were in the approximate range of 15 to 18 W·m<SUP>-1</SUP>·K<SUP>-1</SUP>.

    The carbonate-containing hydroxyapatites were prepared by heating the starting solutions in the Ca (NO<SUB>3</SUB>) <SUB>2</SUB>- (NH<SUB>4</SUB>) <SUB>2</SUB>HPO<SUB>4</SUB>- (NH<SUB>2</SUB>) <SUB>2</SUB>CO-HNO<SUB>3</SUB>-H<SUB>2</SUB>O system with various additives, such as organic solvents and cations, in order to control the morphologies of the particles. The precipitates derived from the starting solution without additive were regarded as the carbonate-containing hydroxyapatite with Ca/P ratio of 1.70; they were composed of the fibrous particles with the long-axes sizes of-50 μm. When the six kinds of organic solvents, i.e, acetone, methanol, ethanol, ethylene grycol and glycerin were added to the starting solution, the precipitates consisted of the fiber- or whisker-like particles with various short- and long-axes sizes. These results showed that the particle size could be controlled by selecting the kinds of the organic solvents. <BR>When various cations were added to the starting solution, the spherical carbonate-containing hydroxyapatite agglomerates formed from the starting solutions with Na<SUP>+</SUP> and Mg<SUP>2+</SUP> additions, whereas the fiber-like hydroxyapatite from the starting solutions with K<SUP>+</SUP>, Sr<SUP>2+</SUP>, Ba<SUP>2+</SUP>, Al<SUP>3+</SUP> and Y<SUP>3+</SUP> additions.

    Nine kinds of composite powders in CaO-P_2O_5-SiO_2-Al_2O_3 system were prepared by the sol-gel process. Although the as-prepared powders were amorphous, hydroxyapatite(HAp)and tricalcium phosphate(TCP)were formed as a calcium phosphate phase when they were heated from 800 to 1300℃. Additionally, anorthite(CaAl_2Si_2O_8)was formed in the composites containing 25 mol% of Al_2O_3 and 25 mol% of SiO_2 at 1100℃. The dense composite of 2.69 g・cm^-3 bulk density was obtained by sintering powders with compositions of 38.48CaO・11.52P_2O_5・25SiO_2・25Al_2O_3 at 900℃ for 5h. When this composite was hydrothermally treated at 160℃ for 24h, β-TCP was changed into HAp to form a porous layer with the 〜8 μm thickness on the surfaces of composites. The porous composite of 2.33 g・cm^-3 bulk density was obtained when the powders with the compositions of 40CaO・10P_2O_5・10SiO_2・40Al_2O_3 were sintered at 1200℃ for 5h. Ricelike HAp particles were formed on the surfaces and fracture surfaces of the porous composite treated hydrothermally at 160℃ for 12h.

    Fibrous carbonate-containing hydroxyapatite (CO<SUB>3</SUB>HAp) which had long axes of about 50 pm was prepared by homogeneous precipitation method, using urea. The fibrous CO<SUB>3</SUB>HAp materials were compressed at a pressure between 50 and 200 MPa to form compacts. The compacts were fired at a temperature between 1100 and 1350°C for 5 h to form the porous hydroxyapatite ceramics. The results obtained are summarized as follows : <BR>(1) Acidic-aqueous solutions (0.1 mol. dm<SUP>-3</SUP> HNO<SUB>3</SUB> 1500 cm<SUP>3</SUP>) containing 0.167 mol·dm<SUP>-3</SUP> Ca (NO<SUB>3</SUB>) <SUB>2</SUB>, 0.1 mol·dm<SUP>-3</SUP> (NH<SUB>3</SUB>) <SUB>2</SUB>HPO<SUB>4</SUB> (Ca/P =1.67) and 0.5 mol·dm<SUP>-3</SUP> (NH<SUB>2</SUB>) <SUB>2</SUB>CO were heated under two conditions : (i) 80°C for 24 h and then 90°C for 72 h or (ii) 80°C for 24 h and then 95°C for 46 h. The fibrous CO<SUB>3</SUB> HAp with Ca/P =1.66 was prepared under both conditions.<BR>(2) Porous hydroxyapatite ceramics which had the porosities of 43% to 10% were easily fabricated from firing the above compacts. The compressed strength of the ceramics with the porosity of 20% showed an average value of 45 MPa in 10 test pieces, ranging from 30 to 60 MPa.<BR>(3) The pore-diameter distribution of ceramics with the total porosity of 39% showed a narrow normal-distribution histogram, ranging from 1 pm to 0.1 pm.

    Porous calcium phosphate film could be formed on a TiO<SUB>2</SUB> substrate by a spray-pyrolysis technique. The aqueous solutions containing 1.0 mol· dm<SUP>-3</SUP> Ca (NO<SUB>3</SUB>) <SUB>2</SUB> 100 cm<SUP>3</SUP>, 0.6 mol· dm<SUP>-3</SUP> (NH<SUB>4</SUB>) <SUB>2</SUB> HPO<SUB>4</SUB> 100 cm<SUP>3</SUP> and conc. HNO<SUB>3</SUB> 6 cm<SUP>3</SUP> were spray-pyrolysed at 600°C for 5, 10 and 15 h, respectively, to form calcium-phosphate layers on TiO<SUB>2</SUB> substrate; TiO<SUB>2</SUB> substrate coated with calcium-phosphate layers was heat-treated at a temperature between 1000°C and 1300°C. The calcium-phosphate film (thickness, -35 μm) containing pores with sizes of -50 μm was formed on TiO<SUB>2</SUB> substrate under the following conditions : the spray-pyrolysis : 600°C and 10 h and the heat-treatment : 1250°C and 5 h. The calcium-phosphate film was bonded to TiO<SUB>2</SUB> substrate through the reaction layers of CaTi<SUB>4</SUB>O<SUB>9</SUB> and amorphous materials in the CaO-P<SUB>2</SUB>O<SUB>5</SUB>-TiO<SUB>2</SUB> system. The surface layer of the film contained chiefly β-Ca<SUB>3</SUB> (PO<SUB>4</SUB>) <SUB>2</SUB>, whereas the bulk contained a-Ca<SUB>3</SUB> (PO<SUB>4</SUB>) <SUB>2</SUB>.

    本研究では、バイオマテリアルのなかで「人工骨」などとして臨床応用されている「バイオセラミックス」をベースとし、生命現象に積極的に働きかける「生命機能マテリアル」を実験と計算科学の融合により開発する。ここでは、生体骨を直接結合する「水酸アパタイトHAp)」および生体内で吸収置換される「リン酸三カルシウム(TCP)」を対象とする。
    より具体的には、実験系研究者からの良質な実験データおよび機械学習などにより収集した情報をもとに「生命機能推定モデル」を構築する。そのモデルを逆解析することにより創り出される「設計図」をもとに生命機能を自在に制御した「革新的バイオマテリアル」を創出する。本研究で対象とする「生命機能」は、骨形成能・生体吸収性・耐感染性(抗菌性)・血管形成能の4つであり、材料単独での高いパフォーマンスを発揮しうる「テーラード型人工骨」を開発し、我が国の「健康寿命の延伸」に貢献する。
    2021年度の取り組みにより、材料特性を十分に把握した人工骨材料の骨形成率を画像解析により定量化し、良質なデータを新たに収集した。それらのデータを特徴量Xおよび目的変数Yとして、骨形成能を予測する「テーラード人工骨創製に資する生命機能予測モデル(Y=F(X))」の構築に成功した。また、2021年度の後半には、このモデルの逆解析により提示された作製条件での材料合成も手掛けている。2022年度は計算結果の予測精度と実際の実験結果(材料特性や生物学的特性)との整合性を向上させる取り組みを推進し、骨形成予測モデルの逆解析による設計図を活用したテーラード型人工骨を創製し、その機能評価を実施する。

    To increase the performance of photo-induced reduction catalyst contributing to green technology, it was investigated to combine nano-particles with different functions; carbon dioxide adsorption materials and photo-induced reduction catalyst. In this research, K-Al composite oxide and strontium titanate was used respectively. In addition, the relationship between "photocatalytic reduction ability" and "carrier life time" was considered from the measurement results using the "microwave photoconductivity decay method". In the future, we will advance the elucidation of the phenomenon at the related phase interface in more detail.

    Hydroxyapatite (HAp) are one of the important key materials in the field of biomaterials. Recently, immunotherapy without side effects has been expected as a novel medical treatment for a cancer. In order to create the novel cell-culture substrates for enhancing the activity of immune cells, we have developed the two types “immunoceramics” on the bases of i) boron-containing apatite (BAp) with BO2 groups and ii) HAp ceramics surface-modified with inositol phosphate (IP6) (hereafter, IP6-HAp ceramics). Splenocytes derived from the spleen of mouse were seeded on these immnoceramics to examine the activation ability using a flow cytometry. The results showed that the populations of splenocytes with the immunoceramics were higher than that of the splenocytes with the HAp ceramics as a control. The present two immunoceramics may be expected as key materials for next-generation immunotherapy for a cancer.

    Osteomyelitis which is often caused from surgical site infection is a serious problem in orthopedic surgery. Although several candidates of osteomyelitis biomarkers were investigated, potential specific biomarkers for diagnosis of osteomyelitis have not been detected yet. Here, we examined the metabolome analysis (CE-TOFMS,LC-TOFMS)to detect specific plasma biomarkers of osteomyelitis using mouse osteomyelitis model. 279 metabolites were detected by the metabolome analyses. Principal component analysis showed that both sphingosine and sphinganine were detected as the highest loading factors.

    Calcium phosphates, such as hydroxyapatite (HAp) are one of the important key materials in the field of biomaterials. Immunotherapy without side effects has been expected as a novel medical treatment for a cancer. Among some immunotherapies, we have focused on the lymphokine activated killer cell (LAK) therapy. In order to develop the novel cell-culture substrates for enhancing the activity of immune cells, we have created the two kinds of “immunoceramics”: i) boron-containing apatite (BAp) with BO2 groups and ii) HAp ceramics surface-modified with inositol phosphate (IP6) (IP6-HAp ceramics). Splenocytes derived from the spleen of mouse were seeded on the above immnoceramics to assay the activation ability by a flow cytometry. The results showed that the populations of splenocytes with the immunoceramics were higher than that of the splenocytes with the HAp ceramics as a control. The two immunoceramics may be expected as key materials for next-generation immunotherapy.

    We have successfully developed novel "chelate-setting apatite cement" using hydroxyapatite particles surface-modified with inositol phosphate. As we have examined the biocompatibility of this apatite cement, it showed good cell differentiation, attachment and proliferation, and bone induction both In vitro and In vivo. Thus, this present study demonstrates that this apatite cement can be useful as a new bone substitute for bone grafting in the spine.

    Biological apatite presented in bone and teeth of mammals contains various minerals, and has lots of defects with nano-scale sizes in the crystal structure. In the present study, we fabricated hydroxyapatite ceramics including bone minerals (bone HAp ceramics) as model materials to clarify the relationship between nano-defect structure and bioactivity of biological apatite. The results of high-resolution transmission electron microscope (HR-TEM) revealed that bone HAp ceramics contained more defects and strains compared to pure HAp ceramics. In addition, osteoblasts derived from rat bone marrow cells were seeded on bone HAp ceramics, together with pure HAp ceramics as a control. The bone HAp ceramics promoted the differentiation into osteoblast compared to pure HAp ceramics. The present bone HAp ceramics may be expected as next-generation artificial bone graft.

    Spinal fusion was conducted in rats using apatite fiber mesh (AFM) loaded with rhBMP-2. The percentage of fusion rate was 100% and concluded that AFM might be effective as a bone substitute in spinal fusion operation. However, as AFM was fragile, we needed to operate carefully on handling. In order to enhance the mechanical properties, we have developed chelete-setting apatite cement using hydroxyapatite particles surfaced-modified with inositol phosphate (IP_6-HAp). The aim of this study is to develop IP_6-HAp as a material for bone grafting. In 2006 and 2007, we have done some studies listed below.
    1. MC3T3-E1 cells were seeded and cultured on IP_6-HAp. After cell culture, the cell number attached on them was counted to examine initial cell-attachment efficiency and cell proliferation.
    2. IP_6-HAps were implanted into tibiae of rabbits, together with a control of Biopex[○!R]-R (PENTAX Corporation, Japan). Within 24 weeks after implantation, the rabbits were sacrificed to retrieve the specimens with the surrounding bone for histological evaluation.
    In experiment 1, The MC3T3-E1 cells cultured on IP_6-HAp showed lower cell attachment and cell proliferation than the control (polystyrene 12-wells plate);. However, cell morphology observed by SEM showed that cells on IP_6-Hap nearly attained to be confluent for 7 days. These results demonstrate that IP_6-Hap have noncytotoxicity.
    In experiment 2, mature bone was seen to have formed around the surface of the IP_6-HAps as compared with Biopex[○!R]-R. The newly-formed bone was in close contact with the cement surface, without any sign of intervening fibrous tissue layer. This result indicates that IP_6-HAp has an excellent osteoconductivity to living bone.
    These results have shown that IP_6-HAp has noncytotoxicity. Furthermore, the hard tissue response of IP_6-HAp is shown to be similar to that of Biopex[○!R]-R. Thus, we conclude that IP_6-HAp is useful as a material for novel bone grafting.

    There is a rapidly increasing number of patients with diseases of their hard-tissue and, given current demographic trends in today's society with a large number of elderly people ; this is an important global problem with severe financial implications.
    In general, hydroxyaptite (HAp) ceramcis, which bonds directly with host bone, is one of a new generation of excellent bioactive materials ; however, HAp has some problems, such as lack of osteoinductivity and relatively inferior mechanical properties as compared with natural bone. In order to overcome the above problems and to provide a high quality of life (QOL) for the aged, we plan to develop novel, high performance biomaterials though control of nano-interface.
    Firstly, we performed the examination study on the development and evaluation of ceramics in medicine through control of nano-interface at 2005 including a bibliography. Thus, we have arrived at a concept of "apatite genomics" which the apatite ceramics give an affect to gene expression of cells, such as osteoblast and osteoclasts, based on control of nano-interface between HAp ceramics and cells. We believe that this concept create novel biomaterials with high-performance properties.
    In addition, we have organized a session "the development and evaluation of ceramics in medicine through control of nano-interface" of 18^<th> Fall Meeting of The Ceramic Society of Japan at the 28^<th>-29^<th> September 2005 in Osaka, and then our reviews have been published to Journal of Japanese Society for Biomaterials.

    The aim of this study is to develop novel scaffolds for hard-tissue regeneration from apatite single-crystal fibers. We clarified a relationship between the properties of the resulting scaffolds and the cellular responses of osteoblasts cultured using the scaffolds.
    In 2003, We have done some studies listed below to evaluate the usefulness of apatite fiber scaffolds as a scaffold of osteoblasts in tissue engineering of bone.
    1.Posterolateral fusion was conducted in rats using apatite fiber mesh loaded with rhBMP-2. within 2 months after the implantation, lumbar spines were excised and the fusion status was evaluated both radiologically and histologically.
    2.Bone marrow cells were seeded and cultured on/in three types of apatite fiber scaffolds with different porosity and pore sizes. After about 2 week's subculture, cells/scaffold composites were implanted into the subcutaneous tissue of athymic mise and excised within 3 months after the surgery for histological examination to determine the extent of ossification.
    In experiment 1, we have examined that the percentage of fusion rate was almost 100%, by using apatite fiber scaffolds combined with rhBMP-2, and concluded that the scaffolds were effective as a carrier of rh-BMP-2.
    In experiment 2, the cells cultured in AFS induced successful ossification, and found that AFS could be useful as a scaffold for tissue engineering of bone. Scaffolds with higher porosity, had a tendency to achieve more pronounced ossification.
    However, as these scaffolds had a high porosity of 98-99%, we needed to operate carefully the scaffolds on handling during in vivo/vitro operation. In 2004, in order to enhance the mechanical properties of the scaffolds, we partly modified the processing of scaffolds utilizing 1. cross-linking of I-collagen with apatite fiber, and 2. precipitation of apatite gel on the apatite fiber, and then successfully create the strengthened scaffolds. The resulting scaffolds showed good cellular responses : initial cell attachment, proliferation and differentiation into osteoblasts.

    本研究の目的は骨粗鬆症などに苦しむ方々が実社会で大いに活躍できるような高度医療・福祉を実現することである。骨の性質は性差や加齢に伴い変化するため、患者一人一人のニーズにあった材料「テーラードマテリアル」を創製するには互いに性質の異なるセラミックスとポリマーとのハイブリッド化が重要な要素技術となる。そこで、本研究では、生体内で力学的に調和しながら最終的に自家骨と置換される新規な無機/有機ハイブリッドを創出する。
    本研究は以下の3つのプロセス、1)生分解性リン酸三カルシウム(TCP)セラミックスの作製、2)生体骨と力学的に調和した生分解性TCP/ポリ乳酸(PLLA)ハイブリッドの創製、3)その生物学的評価に基づいて推進している。ハイブリッド化は開放気孔からなるTCP多孔体をマトリックスとして、その気孔内にPLLAを導入し、TCPとPLLAとが三次元的に相互連結した微細構造を構築する。もし、マトリックスであるTCP多孔体の気孔率を制御できれば最終的に得られるハイブリッドのヤング率を制御可能となる。
    上記の視点にたち、平成15年度はTCP多孔体の作製条件の検討を検討し、リン酸カルシウムファイバーから気孔率を40%から55%の範囲で任意に制御可能なTCP多孔体を作製した。ついで、平成16年度はこの多孔体の内部に酵素重合法によりPLLAを導入して緻密なTCP/PLLAハイブリッド材を創製した。このTCP/PLLAハイブリッドは相対密度が95%程度と緻密な構造をしており、その力学特性は既存のバイオマテリアルの中では生体骨のそれに近い。平成17年度は得られたハイブリッドの生体適合性の評価に注力した。すなわち、作製したハイブリッド材に骨芽細胞を播種し、その初期付着率・細胞増殖性・細胞形態・細胞分化・石灰化について調査した。その結果、ポジティブコントロールであるアパタイトセラミックスと比較して、本ハイブリッド材はアパタイトと遜色ない優れた生体適合性を有することが見出された。今後はin vivoでの動物実験による検証が必要である。

    According to the results of in vitro studies using MC3-T3 cells and bone marrow cells in 2002, hydroxyapatite fibers (HAF) might be useful either as a carrier of rhBMP-2 and a scaffold for bone regeneration to support 3D cell proliferation. In 2002, we have made posterolateral fusion model of rats. Using these models, in 2003, we made two studies, 1) to evaluate usefulness of HAF as a carrier of rhBMP-2 in vivo with future implication of clinical use for posterolateral spinal fusion surgery, 2) to evaluate the biological property and usufulness of hydroxyapatite fiber as a scaffold of osteoblast using rat osteoblastic cells in vivo. Experiment 1) Bilateral posterolateral fusion between L5 and 6 was performed to 14week old Wistar rats using HAF containing rhBMP-2 (5, 10, 16μg). Specimens were retrieved and spinal bone fusion was assessed after implantation. Experiment 2) Osteoblastic cells were isolated from skulls of 1day old wistar rats. Diameter of pores and porosity of HAFs used in this study were controlled to be 5μm and 95% (S0), 250μm and 99%(52000) respectively. 5×10^6 cells were seeded in each scaffolds. The subcultures were performed for 2weeks. Scaffolds with osteoblastic cells were implanted in the back of 4-week-old athymic mouse at the subcutaneous site. Specimens were retrieved after implantation. Bone formation was evaluated by pathologic findings. Result 1) Bone fusion was observed at 4 weeks in all specimens in the group of 15μg rhBMP-2. Result 2) Enchondral bone formation was found at all the cells cultured in the scaffolds implanted in vivo. S2000 scaffolds were porose and able to support 3D cell proloferation comparing with S0. They could introduce new bone formation inside the scaffolds in vivo. But they decreased in size due to their mechanical fragility. Thus we conclude that HAF is not only an acceptable material for delivering rhBMP-2 to a fusion site, thereby enhancing solid posterolateral spinal fusion, but also a scaffold for bone regeneration to support 3D cell proliferation.

    Molecular dynamics simulation has been perfonned to study crystal growth from ionic melts. The periodic boundary condition was imposed in the x-, y- directions while in the z-direction the top of the cell was open to a vacuum. For NaC1, crystal growth on (100), (110) and (111) planes has been studied. After melting the ions at 6-14 layers, crystal growth was started by keeping all the ions at a given temperature except for the bottom layer. The crystal grew in the [100] direction not only in the (100) system but also in the (110) system. Quite a similar tendency has been found also for MgO. The growth rate as a function of temperature is found to have a maximum.
    For CaC1_2 having a distorted rutile structure crystal growth has been studied on (001), (100) and (110) planes. In this case, crystal grew only on the (001) plane within an MD time of about 1 ns, presumably because charge neutrality is maintained on this plane. However, its growth rate was slower than that of NaCl-type by a factor of 100.On a molecular level, it seems that crystal grows in a small charge neutral unit such as a cationanion pair. In the case of NaC1-type, cation-anion pair can become such unit. On the other hand, in CaCl_2, one Ca^<2+> plus two C1^<-'>s are needed to fonn such a unit, in which a defect can be easily generated. The defects will, in turn, retard further crystal growth, and therefore crystal growth is slow. For CaSiO_3 having the perovskite structure, two kinds of cations compete the position of one layer for crystallization. Further, since the viscosity is high the growth rate is very slow even in the (001) plane.
    A video film (ca. 52 min. for the running time) has also been made on crystallization from MgO melt.
