Figure 4. Characterization of MERRF hiPSC-derived cardiomyocytes (MERRF hiPSC-CMs).

Figure 4

(A) Immunofluorescence of MERRF hiPSC-CMs stained with cardiomyocyte markers, including cTNT, α-actinin, MYL7 and MYL2. Nuclei were counterstained with Hoechst 33342 (blue). Scale bar, 10 μm. (B) mtDNA A8344G mutation rate quantified by pyrosequencing of MERRF hiPSCs and MERRF hiPSC-derived cardiomyocytes. M1-CM and M2-CM, MERRF hiPSC-derived cardiomyocytes carried mtDNA A8344G mutation. M1ctrl-CM, hiPSC-derived cardiomyocyte carried normal mtDNA.
