Effects of salvianolic acid and notoginseng triterpenes on angiogenesis in EA-hy926 cells in vitro

AimTo investigate the different effects of salvianolic acid and notoginseng triterpenes on proliferation, angiogenesis and expression of vascular endothelial growth factor in EA-hy926 cells in vitro.MethodsEA-hy926 cells were cultured in vitro. Salvianolic acid and notoginseng triterpenes at concentrations of 0.4, 0.8 and 1.2 mg·L−1 were used to culture EA-hy926 cells. EA-hy926 cells in a blank control group were grown in culture solution only. Viability of cells was assessed by CCK-8, and after treated for 12 h, capillary-like structures were examined. After 24 h culture, the expression of VEGF was detected by real-time PCR.ResultsSalvianolic acid at 0.4, 0.8 mg·L−1, the same as notoginseng triterpenes, increased VEGF content in EA-hy926 cells. Expression of VEGF protein in the salvianolic acid at 1.2 mg·L−1 group, was up-regulated as compared with notoginseng triterpenes group (P < 0.05).ConclusionSalvianolic acid and notoginseng triterpenes can promote EA-hy926 cell proliferation, angiogenesis and expression of VEGF protein. This analysis also provided evidence that salvianolic acid had the better effects as compared with notoginseng triterpenes.
