Outline of Research at the Start

アキレス腱断裂では社会復帰やスポーツ復帰までの期間を短縮する治療法が望まれ、アキレス腱欠損では完璧な機能を回復する治療方法は現在まで確立されていない。近年、自己血液製剤の多血小板フィブリン(PRF)が注目され、様々な分野で臨床応用が期待されている。本研究ではアキレス腱疾患に対するPRFの臨床応用への第一歩として、アキレス腱欠損モデルラットを用いてPRFがアキレス腱修復に及ぼす影響を検討し、さらに腱修復に重要な役割を持つ腱細胞(tenocyte)に対するPRFの効果について検討する。本研究を通じて、PRFの有用性が確認できれば、アキレス腱断裂やアキレス腱欠損に対する新規治療へ繋がる可能性がある。

Outline of Final Research Achievements

Platelet Rich Fibrin (PRF) is a fibrin mass containing high growth factors concentrations. It is expected to promote healing in various pathological conditions due to its sustained release properties. We evaluated PRF directly on Achilles tendon defects in an animal model. We aimed to identify its effect on tenocytes, which play an essential role in tendon repair, and the signaling pathways involved. We found that PRF promotes tenocyte proliferation via FGF receptor/Akt signaling and tenocyte activation via TGF-β receptor/Smad3 signaling to promote Achilles tendon injury healing.

Academic Significance and Societal Importance of the Research Achievements

本研究を通じて、PRFはアキレス腱損傷の治癒促進に有用であること、特にPRFに含まれるFGF受容体/Aktシグナルを介してtenocyteの増殖を促し、 TGF-β受容体/Smad3シグナルを介してtenocyteを活性化させるというアキレス腱損傷治癒のメカニズムを明らかにした。本研究によりPRFを直接アキレス腱損傷の治療に応用できる可能性や特に重要な成長因子であるFGFやTGF-βを腱損傷の治療に応用できる可能性が示唆されており、今後の新規治療法の開発への一助になったものと考える。
