Abstract

Heart is the first organ to function during mammalian embryogenesis. The differentiation of embryonic stem cells (ESCs) into cardiomyocyte is complex and dynamic, which involves 4 differentiation stages including ESCs, mesoderm, cardiac precursor, and terminal cardiomyocytes. Abnormal expression of certain genes can lead to congenital heart diseases during cardiomyocyte differentiation. Epigenetic regulation plays a crucial role on the switch of gene activation and deactivation during cardiomyocyte differentiation. Non-coding RNA, particularly microRNA and long non-coding RNA, may significantly influence gene expression. Exploring the regulatory roles of non-coding RNA in cardiomyocyte differentiation may contribute to the understanding of the functions of myocardial cells and mechanism of congenital heart diseases.
