The wound healing rate of human endothelial cells (HUVECs) was measured via in vitro scratch assay throughout 24 h and 48 h (A). Result showed that wound healing rate of treated cells was decreased after 24 h and 48 h (B). Data are prepared as mean ± standard deviation. The means were compared using a T-test. *P < 0.05 and **P < 0.01. n = 3. Scale bar: 250 µm
