Outline of Research at the Start

筋サテライト細胞 (MuSC: Muscle Satellite Cell) は通常は、細胞周期G0期 (静止期) で維持されている。一方で、レジスタンストレーニング等の骨格筋への過負荷刺激により、MuSCは活性化・増殖後に筋線維へ新たな核を供給する事で筋肥大に働く。つまり、MuSCは「日常動作」と「レジスタンストレーニング」の動き(機械刺激)の違いを区別していると考えられる。しかしその分子メカニズムは不明である。本申請課題では、MuSCの能力を利用した筋疾患・筋萎縮治療法への応用を最終目標として、マウス筋肥大モデルやMuSCの静止期維持シグナルに焦点をあてる事でMuSCが異なる筋の動きを感知する分子機構解明に取り組む。

Outline of Final Research Achievements

It is generally considered that muscle stem cell proliferation is triggered by the damages of myofibers in resistance training. However, in our previous study, we found that muscle stem cells proliferate even without the damages to myofibers (Elife. 2019;8:e48284.). In this proposal, we discovered the relayed signaling between interstitial cells and muscle stem cell via Yap/Taz-Thbs1-CD47 axis. We also founded that the down-regulation of calcitonin receptor ensure the proliferation of MuSC in training muscle.

Academic Significance and Societal Importance of the Research Achievements

一般的には,物理的刺激により筋線維が壊れることがサテライト細胞の活性化・増殖を誘導すると考えられていました。そのため筋サテライト細胞が運動依存的に増殖するために,損傷は必要なく,間質の細胞が必要であることはこれまでの常識を塗り替える成果となりました。また,核は細胞のまさに「核」であり,老化や病気によってその質が低下します。損傷も物理的負荷もない条件でも,筋線維核を増加できる事は,筋線維核の機能が低下する疾患への応用が期待されます。
