Figure Lengend Snippet: Generation and characterization of iPSC-derived cardiomyocytes. A. Schematic overview of the experimental design. B. Reprogramming factor expression in control and MRPL44 patient-derived iPSCs after reprogramming (OCT4; green, NANOG; red and TRA-1-60; green) (Scale bar; 200µm) C. Cardiac marker positivity of iPSC derived CMs. Immunofluorescence, cardiac troponin (cTnT; green) and nuclei (DAPI, blue) (Scale bar; 50 µm). D. Purification of iPSC derived cardiomyocytes. Representative FACS analysis shows 91.9% cTnT positive cells after purification.

Article Snippet: Contracting cells were observed from day 8 onwards. iPSC derived CMs were purified using magnetic beads as per manufacturer’s instructions (#130-110-188, Miltenyi Biotec) on day 15-20 of differentiation.
