Identification of human peripheral blood-derived EPCs. a The isolated human peripheral blood-derived EPCs exhibited the typical endothelial-like cobblestone morphology. b Immunofluorescence staining revealed that the cell population was positive for CD34 (left), vWF (middle) and CD31 (right). DAPI was for nuclear counterstain. c Tube-like structures were generated after EPCs were seeded onto matrigel-coated dish. This experiment was repeated independently three times. Abbreviations: EPCs, endothelial progenitor cells; DAPI, 4, 6-diamidino-2-phenylindole; vWF, von Willebrand factor
