Outline of Final Research Achievements

Recent studies have suggested that different signaling pathways regulate chondrocytes in different layers of articular cartilage. We examined characters of these chondrocytes and identified that WNT and Notch signaling differently regulate differentiation of superficial zone chondrocytes and deep chondrocytes. We have further revealed the molecular mechanisms of mechanosensing in superficial zone.

Academic Significance and Societal Importance of the Research Achievements

変形性関節症は、関節軟骨の変性に始まり、周辺の骨の硬化性変化、滑膜の炎症性変化を伴って進行し、関節痛を引き起こして運動機能を著しく低下させる疾患である。その治療法には近年目立った進歩はなく、末期患者には人工関節置換術などの手術療法が選択されるものの、病態を制御しうるような本質的な治療法はいまだ存在しない。本研究の成果は関節軟骨がどのように制御されているか、その本質に迫るものであり、今後の治療薬開発の基盤となるものと考える。
