Fig. 4. Effects of phenolic compounds on the capillary-like tube formation of human retinal microvascular endothelial cells. The inhibitory effect of phenolic compounds on migration was investigated by capillary-like tube formation assay. The number of tube structures was counted manually. (A) Morphological changes, (B) number of tube structures. Statistical significance was compared with the control group at #P<0.05 and with the vascular endothelial growth factor (VEGF) group at ***P<0.001, **P<0.005, and *P<0.05 (n=3).
