AKE inhibits tube formation in human vascular endothelial cells. (a) Human vascular endothelial cells were treated with serum-free media containing AKE or CA (0–10 μg/mL) with recombinant human VEGF (20 ng/mL) for 17 h. Tube formation on Matrigel was observed with a microscope. (b) The bar graph represents the quantification of tube formation. Data are expressed as mean ± SEM, , versus control.
