| Outline of Final Research Achievements |
Cardiomyocytes derived from human iPSCs are expected to be applied not only to transplantation but also to drug discovery. However, since the cardiomyocytes obtained by the existing differentiation induction method are still immature, they are not sufficiently satisfied for the application of drug evaluation. In this research project, we aim to develop an accelerated maturation method of novel pluripotent stem cell-derived cardiomyocytes without using physical stimulation from outside. The applicant discovered the closed loop and the phenomenon that action potential propagates to acceleration by the developed device. The ohenomenon was named travling wave. Furthermore, with the training by travling wave, we aim to develop an accelerated cardiomyocyte maturation method based on the spontaneous and circulating progressive waves safely, simply and stably, that is, the development of a pluripotent stem cell-derived myocardial permanent machine.

| Academic Significance and Societal Importance of the Research Achievements |
This technology could be a promising substitution for harmful electrical stimulation method. It can be expected that this new technology, could be of great usefulness and importance for both researchers and industrial/clinical users in the fields of drug screening and heart regeneration.
