Outline of Final Research Achievements

The extracellular matrix protein Tenascin C, which we focused on in this project, was particularly important for the soft palate development. We confirmed their expression in the posterior part of palatal shelves by immunohistochemical staining using mice embryos. We found that this Tenascin C expression was dramatically inhibited in TGF-β receptors and Sonic Hedgehog mutant mice, which are expressed in palatal epithelium. In conclusion, we clarified the roles of TGF-β and Sonic Hedgehog as factors that promote the expression of Tenascin C, which is important for soft palate formation.

Academic Significance and Societal Importance of the Research Achievements

口蓋は胎児期に左右から成長する口蓋突起が正中で癒合することで形成されるが、このプロセスが障害されると口蓋裂という顔面奇形を生じる。治療は主に外科的な閉鎖だが、軟口蓋領域は組織量が十分でないと理想的な閉鎖は難しい。そこで、閉鎖術の前に十分な組織量を得るための再生医療学的手法の開発が望まれている。本研究は、軟口蓋形成を誘導するための担体を構成する細胞外基質蛋白候補としてTenascin Cを示すことができ、さらにTenascin Cの分泌を促進する因子として、TGF-βやSonic Hedgehogといった分泌蛋白の役割を示すことができたことは、今後の口蓋裂治療においても意義のあるものといえる。
