Figure 1. Effect of homoisoflavanone on fibroblast growth factor-2 and human umbilical vein endothelial cells. A: Each figure is representative of three independent experiments. B: Basal tube formation of human umbilical vein endothelial cells (HUVECs) left in serum-free media was normalized to 100% respectively. Each value represents means ± SEM from three independent experiments (*p<0.05).
