Fig. 2.
The inhibitory effects of hesperetin on cell viability of HUVECs. HUVECs were cultured with hesperetin (0~200 μM) in the presence of VEGF (50 ng/mL) for 24 h. Cell proliferation is expressed as the percentage of viable cells cultured in the absence of hesperetin and is expressed as the mean±SD. *P<0.05, **P<0.01 compared to control.
