Outline of Research at the Start

本研究では、その一軸配向化高靱性コラーゲンゲル線維および天然腱マトリクス(比較対照)を異なる生物学的および物理的環境(関節内・外、生理的負荷・除負荷)に移植して、それらの生体内再構築現象および影響因子の効果の差を世界に先駆けて明らかにする。さらにその結果は生体医工学領域の最重要課題の一つである「腱・靱帯マトリクスの生体内再構築現象に関する機能的適応制御機序の解明」に貢献する。

Outline of Final Research Achievements

We have developed uniaxially aligned artificial collagen gel fibers with a cell invasion pathway using our continuous molding technology. Uniaxially aligned artificial collagen gel fibers was implanted in a slit prepared in the centre of the rabbit patellar tendon. After 12 weeks after implantation, the artificial tendon was absorbed and replaced to collagen tissue with cellularity. Fibroblasts were sparsely scattered between the collagen fibers.

Academic Significance and Societal Importance of the Research Achievements

本研究は、世界初の生体材料である一軸配向化合成コラーゲン線維束の生体内再構築過程を解明する独創的研究であり、生体医工学領域の重要課題である「腱・靱帯組織の機能的適応制御機構」の一端を解明しようとする学術的な研究である。本研究結果は、今後「生体内で合目的なリモデリングを受け得る合成腱マトリクス」という世界に類を見ない医用生体材料を開発するための重要な基礎情報を与えることに大きな社会的意義がある。
