miR-708 promoted differentiation of cardiac stem/progenitor cells to cardiomyocytes. (A) Cardiac stem/progenitor cells were transfected with miR-708 mimics or control miRNA mimics followed by a three-week induction of differentiation; (B) Confirmation of miR-708 overexpression by QRT-PCR after transfection of miR-708 mimics into c-kit(+) cells; (C) Gene expression analysis of cardiomyocyte markers TnnT2 and NKX2.5 in c-kit(+) cardiac stem/progenitor cells before and after differentiation (one week) with or without the overexpression of miR-708. Data are mean ± SEM (n = 3). ** p < 0.01.
