With exposure to either normoxia or hypoxia, expression of CD31, Flk-1, and VE-cadherin in hASCs treated with VEGF (50 ng/ml) and BMP4 (100 ng/ml) for 14 days was determined by A immunofluorescent staining, B FACS analysis, C real-time PCR, and D western blot analysis, which was quantified and normalized to the expression levels of β-actin (E). Data are presented as mean ± SD. *P < 0.05
