FIG. 3.

Characterization of human umbilical vein endothelial cells (HUVECs) and pericytes. (A, D) The representative phase-contrast light microscopic images showing the characteristic morphology of HUVECs and transforming growth factor-beta (TGF-β)-induced pericyte phenotype of hMSCs. (B) The representative confocal microscopic image showing the immunostaining of HUVECs against CD-31 and (C) the image showing low-density lipoprotein uptake. (E, F) The confocal images of pericytes showing positive immunoreactivity against smooth muscle actin and calponin, respectively.
