The differentiation rate and the expression of VEC genes. A Different doses of CPP (0, 1, 10 or 20 μM) were used to treat HDFs for 10 days, and then the ratio of the number of CD31-positive cells to the total number of cells was counted. Different doses of CPP (0, 1, 10 or 20 μM) were used to treat HDFs for 10 days, and treated HDFs expressed VEC genes and proteins measured by qRT-PCR (B–F) and flow cytometry (G–H), respectively. Data are presented as means ± SEM, *P < 0.05, **P < 0.01, ***P < 0.001, n = 3
