| Research Abstract |
The purpose of the present study was to clarify pacemaking mechanisms of human cardiac pacemaker cells, SA node cells. In order to achieve the goals, I performed cellular physiological experiments using human iPS-derived cardiomyocytes and mathematical simulations. Several combinations of chemicals enhanced proliferation of human iPS-derived cardiomyocytes, with similar electrophysiological characteristics. Theoretical analyses suggested that coupling of mitochondrial and sarcoplasmic reticulum Ca dynamics is important for pacemaking, and that contribution of mitochondrial Ca transporter is mechanism dependent.
