Fig. 5. Effects of phenolic compounds on the monolayer permeability in human retinal microvascular endothelial cells. The monolayer permeability demonstrates an increase of FITC-dextran level. The relative FITC-dextran intensity was normalized by control. Statistical significance was compared with the control group at ###P<0.001 and with the vascular endothelial growth factor (VEGF) group at ***P<0.001, **P<0.005, and *P<0.05 (n=3). FITC, fluorescein isothiocyanate.
