| Outline of Final Research Achievements |
The established differentiation of cardiomyocytes derived from iPS cells are expected to result in better efficacy of cell transplantation therapy. The differentiating cardiomyocytes were transplanted onto adult nude rate hearts. In the transplanted iPS cardiomyocytes in vivo, cardiac specific marker was much more expressed than the cardiomyocytes cultured in vitro. This result suggests that the environment that imitates the condition of cardiomyocytes differentiation promote the differentiation of iPS-CMs. The mechanical stretch modulated cell alignment and maturation gene expression in vitro.
The differentiation of cardiomyocytes derived IPS cells might be promoted in vitro by mechanical stretching.
