Morphologies of cells differentiated from pEpiSCs, pBM-MSCs and pA-MSCs. Morphologies of porcine epiblast stem cells (pEpiSCs), porcine bone marrow-derived mesenchymal stem cells (pBM-MSCs) and porcine adipose-derived mesenchymal stem cells (pA-MSCs) cultured in differentiation medium (EBM-2 + 50 ng/mL VEGF) on cultured plates coated with matrigel® (1:40 dilution with DMEM/F-12 medium) on the day 2, 5 and 8. Cells differentiated from pEpiSCs showed an elongated spindle-like morphology, whereas cells differentiated from pBM-MSCs showed a round pebble-like morphology. In the case of pA-MSCs, these two morphologies were mixed with each other on the day 2, 5 and 8, respectively. Scale bar = 200 µm.
