摘要
观察肝细胞生长因子(HGF)对体外培养的牛冠状动脉血管内皮细胞 (BCAEC)、牛冠状动脉血管平滑肌细胞 (BCASMC)和小鼠心肌细胞血管内皮细胞生长因子(VEGF)分泌的影响。BCAEC对照组与HGF组 12hVEGF浓度分别为 10 5 1± 2 90和 9 31± 2 78pg/ml;BCASMC对照组和HGF组 12hVEGF浓度分别为 3h的 3 35倍和 3 93倍 ,HGF组 3h和 12hVEGF浓度分别为对照组的 2 0 6倍和 2 4 2倍 ;心肌细胞对照组和HGF组 12hVEGF浓度分别为 3h的 5 4 3倍和 4 0 9倍 ,HGF组 3h和 12hVEGF浓度分别为对照组的 2 74倍和 2 0 6倍。提示BCAEC、BCASMC及小鼠心肌细胞均具有自分泌VEGF的作用 ,HGF促进BCASMC和心肌细胞VEGF的分泌 。
The effects of hepatocyte growth factor(HGF) on the secretion of vascular endothelial growth factor(VEGF) in cultured bovine coronary artery endothelial cells(BCAEC), bovine coronary artery smooth muscle cells(BCASMC) and mouse cardiomyocytes were observed in vitro . The concentrations of VEGF in BCAEC control and HGF group at 12h were 10.51±2.90pg/ml and 9.31±2.78pg/ml, respectively. The concentrations of VEGF at 12h in BCASMC control and HGF group were 3.35 and 3.93 times of that at 3h respectively, the concentration of VEGF at 3h and 12h in BCASMC HGF group was 2.06 and 2.42 times respectively, of that in control group. The concentrations of VEGF at 12h in cardiomyocyte control and HGF group were 5.43 and 4.09 times, respectively, of that at 3h, and the concentrations of VEGF at 3h and 12h in cardiomyocyte HGF group was 2.74 and 2.06 times, respectively, of that in control group. These results indicated that BCAEC, BCASMC and mouse cardiomyocytes could secrete VEGF, and HGF could promote VEGF secretion in BCASMC and cardiomyocytes, but not in BCAEC.
