Sarcomeric organization in cardiomyocytes derived from iPS and ES cells. Cardiomyocytes isolated from contracting areas of day 60 EBs from IMR90 C4, Foreskin C1, H1 and H9 were co-labeled for α-actinin (green) and MLC2a (red). Nuclei were stained with Hoechst (blue). Overlap of α-actinin and MLC2a labeling demonstrated an alternating pattern of sarcomeric labeling consistent with MLC2a present in the A band of the sarcomere between the Z-lines demonstrated by the α-actinin labeling. Scale bars are 20 μm.
