The effect of COE and BP on the migration of human umbilical vein endothelial cells. a COE and BP suppressed migration in HUVECs in the wound healing assay. The cells were treated with COE and BP and incubated at 37 °C. After 12 h, the number of cells that had migrated into the scratched area was calculated. b The bar graph represents the quantification of migrated cells from the untreated control, the COE-treated and the BP-treated groups. The data are presented as the mean ± SE. (n = 3; * p < 0.001 vs. the control group)
