Angiogenesis of HUVECs cultured in different coatings in vitro. A Maps of wound healing scratch. B Migration distance of HUVECs. C The number of migrated cells. D Images of the transwell experiment. E Number of cells migrating to the inferior chamber. F Tube formation in vitro. G Statistical analysis of tube number. Microscope magnification was ×100. Scale bar = 200 μm. *P < 0.05, **P < 0.01, ***P < 0.001 and ****P < 0.0001 were obtained by comparison with uncoated Ti
