Postn knockdown reduces differentiation of P19 cells into cardiomyocytes. ShPostn, knocking down Postn; DMSO, Dimethyl sulfoxide; A shows the cells induced with 1% DMSO exhibited better morphology than those induced with 10%. B shows the cells at day 15 of induction by DMSO, where both anti-a-SAM (green) and anti-cTnT positive (red) are considered successfully induced DAPI, blue represent nucleus. These findings suggest that knock-down of Postn reduces the degree of differentiation of P19 cells into cardiomyocytes. *P < 0.05
