Effects of KGE on HUVECs endothelial tube formation. HUVECs were incubated with various concentrations of KGE (50–1000 µg/ml) for 24 h. The upper panel indicated the quantification of tube formation and the lower one showed the tube network formed by HUVECs. Values are presented as the means ± SD of three independent experiments. All data were analysed by ANOVA with multiple post hoc testing. * p < 0.05, ** p < 0.01 vs control.
