Relative expression of cardiomyocyte-specific genes and ion channel genes by qRT-PCR. a The expression levels of cardiomyocyte-specific genes in the electrical stimulation group were higher than those in the control group. b The expression levels of ion channel genes except KCNJ2 and KCNJ12 in the electrical stimulation group were significantly increased at day 14 compared to those in the control. *, P < 0.05; **, P < 0.01; ***, P < 0.001
