The different phenotypes of the MNCs in different conditions. a Rat MNCs from bone marrow in CM formed colonies surrounded by spindle-shaped cells (magnified 10×). b Rat MNCs from bone marrow in CM differentiated into a cobblestone-like morphology (magnified 10×). c Rat MNCs from bone marrow in EGM-2MV formed a fusiform shape (magnified 10×). d EPCs formed capillary-like sprouts on Matrigel (magnified 10×). e The expression of eNOS in EPCs induced by different media for different culture times
