摘要: The efficient induction of cardiomyocyte differentiation from embryonic stem (ES) cells is crucial for cardiac regenerative medicine. Although Wnts play important roles in development, complex questions remain as to when, how and what types are involved cardiogenesis. We found that Wnt2 was strongly up-regulated during ES cells. Therefore, we investigated when acts cardiogenesis cell differentiation. expressed the early developing murine heart. applied this expression pattern differentiation, elucidate function knockdown revealed intrinsic essential Moreover, exogenous increased Interestingly, effects on addition were temporally restricted. During cells, didn't activate canonical Wnt pathway but utilizes JNK/AP-1 which required Therefore conclude plays strong positive stage-specific role through non-canonical
