Directed differentiation into cardiomyocytes using hiPSC at high passages yields positive cells for cardiac markers. (a) Immunostaining of cardiomyocytes (iPSC-CMs ACP5) obtained from ACP5 clone showing protein expression of cardiac specific-markers TNNI1, TNNI3, MYH7, TNNT2, NKX2.5 and ACTN2. Nuclei was stained with Hoechst 3342. (b) and (c) FC data showing protein expression of cardiac-specific markers TNNI1, TNNI3, TNNT2 and ACTN2 in hiPSC-CM. Results were confirmed by performing independent experiments using APC5, PC4.3, PC4.5, PC4.6. Data is presented as mean ± SD, n = 2–5; one-way ANOVA p = 0.9 (ACTN2); 0.2 (TNNI1); 0.9; and 0.1 (TNNT2).
