Cultured EPDCs do not display markers of other heart-resident cell types. Immunofluorescent staining confirmed the absence of αSMA in both (a) fetal and (b) adult EPDCs, using mesenchymal cells as positive control (scale bar: 50 μm). c EPDCs were negative for the endothelial marker PECAM1 (scale bar: 50 μm). Human umbilical vein endothelial cells (HUVECs) were used as positive control. d qRT-PCR analysis confirmed the absence of markers attributed to cardiac progenitor cells, the endocardium, hematopoietic system, and myocardium.
