Outline of Annual Research Achievements

骨外における骨形成能(骨誘導能)は大規模骨欠損の再建に有効であると考えられている。しかし、骨誘導メカニズムは未だ解明されていない。骨誘導メカニズムの解明に向けて、骨誘導を確実に引き起こす材料の開発と、その材料を筋肉内にインプラントした際に生じる細胞・組織応答の病理組織学的解析による解明に取り組んできた。本年度はn数を増やし、より信頼性のあるデータを得ることを試みた。ウサギ筋肉内にハニカム人工骨を埋植後、1、2、3、4、8、12週後に摘出し、細胞・組織応答の経時変化を解明した。組織切片のヘマトキシリン-エオシン(HE)、酒石酸耐性酸性フォスファターゼ(TRAP)、オステオカルシン(OC)、抗ラビットマクロファージ抗体(RAM-11)、マッソントリクローム(MT)、ヴィラヌエバ・ゴールドナー(VG)染色を行い、フィブリン、血管、破骨細胞、骨芽細胞、マクロファージ、コラーゲン、成熟骨、類骨等の変化から骨誘導メカニズムを組織学的に解明した。埋植後2週目まではフィブリンの濃縮が進行した。3週時点で劇的な組織学的変化がみられ、コラーゲンの生成、TRAP-positive細胞及びRAM-11-positive細胞の大量出現、材料を貫通する血管の形成が確認された。4週時点では、TRAP-positive細胞及びRAM-11-positive細胞の急激な減少、OC-positive細胞の出現、コラーゲンの増加が確認された。8週時点では、TRAP-positive細胞及びRAM-11-positive細胞のさらなる減少とOC-positive細胞の増加が確認された。12週目にハニカム内に石灰化骨の形成が確認された。また、これまでの報告では、材料内部から骨形成が進行するとの報告があるが、ハニカム人工骨の場合は、材料の端から内部に向かって細胞・組織応答が進行していることが確認された。
