Outline of Final Research Achievements |
We currently focus on the novel role of satellite cells in the myofiber-type regulation. Our previous studies proposed that satellite cell cultures from soleus muscle (slow-myofiber abundant) synthesized and secreted larger amount of semaphorin 3A (Sema3A) than extensor digitorum longus (EDL; fast-myofiber abundant) and Sema3A promoted the slow-twitch myofiber formation. In this study, we focused on Netrins characterized as multi-functional modulators like Sema3A also importantly mediate myofiber-type commitment early before motor-neural stimulations. Initially, we detected the expression levels of Netrins during myogenic differentiation phase. Next, the satellite cells from EDL expressed higher levels of Netrin-1 than those from soleus. Netrin-1 knockdown experiments in satellite cell cultures performed the inhibition of fast-myotube formation. Taken together, these results suggest that satellite cell-derived Netrin1 may be the key modulator for the fast-myofiber-type commitment.

Academic Significance and Societal Importance of the Research Achievements |
食肉の原料となる骨格筋は、主に筋細胞(細長い巨大な細胞のため“筋線維”と呼ばれる)から構成される。筋線維は、収縮特性や代謝特性等の違いによって遅筋型または速筋型といった筋線維型で分類される。これまでに、筋線維型は成熟した筋線維に接着する運動神経刺激によって制御されると考えられてきたが、本研究成果より、各筋線維型に特異的な衛星細胞はそれぞれで多量に産生する多機能性の細胞外制御因子によって、筋管の筋線維型を制御する「早期決定機構」の存在が明らかとなった。本機構の応用により、容易に筋線維型を変換することで、食肉の質を自在にコントロールできる新技術開発に繋がることが期待される。
