Differentiation of major histocompatibility complex (MHC)-I-homozygous parthenogenetic stem cells (pSCs) into cardiomyocytes. (A) Morphology of undifferentiated pSC colonies at passage 21 cultured on murine embryonic fibroblasts. Scale bar: 500 µm. (B) FACS analysis of MHC class I molecules on unselected derivatives of an MHC-heterologous control pSC-line (left panel) and on the MHC-homologous pSC30B3-line used in this study (right panel), both generated from oocytes derived from the MHC-heterologous B6D2F1 mouse-strain. (C) Confocal microscopy of pSC-derived cardiomyocytes. Scale bars: 20 µm. (D) FACS-analysis of cardiomyocyte-specific proteins in pSC-derived cardiomyocytes after 7 days of chemical purification with G418 (MHC: myosin heavy chain). Left panels: Representative scatter blots. Right panel: Summary of the flow cytometry data (n = 4–12/group).
