Research Abstract |
The aim of this study is to establish 3D culture for transplantation to the infarcted heart. Cardiac stem cells obtained as c-kit positive cells from adult rat hearts were used as a cell source. Even if we use the same method to obtain c-kit positive cells, different genes expression pattern was observed after the long-term culture. Among the various cardiac stem cells (CSCs), GATA4 high-expressing CSCs showed more potential to differentiate into cardiac myocytes than GATA4 low-expressing cells in vitro. Furthermore, these GATA4 high CSCs had more survival effect on the co-cultured cardiacmyocytes derived from adult rat heart than GATA4 low-expressing CSCs. Therefore,GATA4 high CSCs are the appropriate cell source for regenerative medicine for heart failure. We also showed that TGF-βsuperfamily associates with myogenesis.
