hEPCs coculture and PDGF‐BB enhanced angiogenic capacity of hMSCs. In vitro angiogenesis was performed in hEPCs, hMSCs, and cocultured cells with or without PDGF‐BB or Ab‐PDGFR at 12 (A), 24 (B), and 48 (C) hours. hMSCs treated with endothelial cell growth medium (EGM‐2) were used as a positive control (EGM‐2‐PC). (D) The average number of tubules was determined in five independent fields at 100× magnification for each well. *P < 0.05, compared to hEPC‐alone group; #P < 0.05, compared to hMSC‐alone group; ▵ P < 0.05, compared to coculture group.
