| Outline of Final Research Achievements |
In this study, in order to elucidate the molecular biological mechanism of muscle memory, we focused on the relationship between muscle memory and ribosome genesis. First, we constructed a cell model suitable for investigating the molecular biological mechanism of muscle memory and established a method using decellularized skeletal muscle as a substrate for skeletal muscle cell culture system. This has enabled us to study the relationship between the extracellular matrix and skeletal muscle cells, which is important in the mechanoreceptor mechanism of skeletal muscle. We are currently using this model to analyze data applied to the elucidation of the molecular biological mechanism of muscle memory.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、マッスルメモリーのメカニズムを研究する上で、新たな細胞培養系を構築した。このモデルは骨格筋の力学的刺激受容機構で重要になる細胞外マトリクスと骨格筋細胞との関連を検討することができるため、マッスルメモリーのメカニズム研究だけにとどまらず、多くの骨格筋研究に応用することができると考えられる。また、マッスルメモリーを上手く引き出すことができれば、アスリートの競技復帰のサポートや、長期入院後のリハビリテーションなどに繋げられる可能性がある。
