Figure Lengend Snippet: Cardiac differentiation from hiPSCs (A) Schematic of the protocol for the differentiation of cardiomyocytes from hiPS cells with (RA (+)) or without RA (RA (−)) treatment (B) The ratio of cardiomyocytes quantified by immunostaining with cardiac troponin-T (cTnT). The proportion of cTnT positive cells was 93.91 ± 2.51% in CT (control hiPS-CMs), or 96.79 ± 1.81% in AM (RA-treated hiPS-CMs), respectively (P = N.S.). Error bars represent SD of the mean from the values of independent experiments. n = 3. N.S., not significant (C) Immunofluorescence analysis of the percentage of MLC2a (atrial isoform) and MLC2v (ventricular isoform) positive expression in the CT and AM. Error bars represent SD of the mean from the values of independent experiments. ** p < 0.01 for comparison with MLC 2a+/MLC 2v-cardiomyocyte in CT, ## p < 0.01 for comparison with MLC 2a+/MLC 2v-cardiomyocyte in AM, n = 3.
