| Outline of Final Research Achievements |
The adult mammalian heart contains several kinds of cardiac stem or progenitor cells. Atypically-shaped cardiomyocytes (ACMs) are derived from mouse heart that spontaneously develop into beating cells. We found that the ACMs can fuse with each other to become multinucleate large beating cells.

| Academic Significance and Societal Importance of the Research Achievements |
心筋細胞は低酸素や機械的刺激、酸性化に感受性が高く、損傷した組織の再生は不可能である。しかし、心臓組織中に低酸素等への耐性の高いACMsが生存していることは、何らかの生理的意義をもつ考えられ、将来の再生技術への手がかりとなる可能性がある。
