| Outline of Final Research Achievements |
We have succeeded in creating an inexpensive soft culture surface for controlling the behavior of human iPS cells. It was clarified that undifferentiated maintenance culture of human iPS cells can be performed only by controlling the hardness of the culture surface without adding expensive cytokines used for maintenance of undifferentiation.
It was clarified that the self-organization of mouse skeletal myoblasts is induced depending on the hardness of the culture surface and ECM. Furthermore, we succeeded in constructing contracting artificial skeletal muscle cells without using scaffolding such as gel or scaffold.

| Academic Significance and Societal Importance of the Research Achievements |
物理刺激のみによってヒトiPS細胞の未分化維持培養ができれば、現在高コストが実用化障壁の1つになっているヒトiPS細胞を用いた細胞治療のための、新たな培養プロセス開発の一助となる。
また、自己組織化を効率的に誘導するプロセスを開発したことによって、より生体内の状態に近い人工骨格筋組織を誘導することができ、世界的な動物実験に対する風当たりの中において、新たな創薬等の研究開発のためのツールとなり得ると考えられる。
