摘要 目的探讨ET-1、TGF-β1对大鼠肺成纤维细胞结缔组织生长因子(CTGF)表达及细胞增殖的影响。方法体外培养大鼠肺成纤维细胞株,分为ET-1干预组、TGF-β1干预组、对照组,ET-1干预组加入含ET-1 10 ng/m L的肺成纤维细胞专用培养基(FM培养基)1 m L,TGF-β1干预组加入含TGF-β110 ng/m L的FM培养基1 m L,对照组加入1 m L FM培养基。各组设8 h及1、2、3、4、5 d六个时间点,ELISA法观察各组各时间点细胞上清中CTGF表达水平,用台盼蓝染色计数活细胞数,绘制细胞生长曲线,计算细胞增殖数。结果各时间点ET-1干预组、TGF-β1干预组CTGF水平均高于对照组(P均<0.01),且随着时间的增加表达水平呈逐步上升趋势。各组细胞数随着时间的增加呈上升趋势,ET-1干预组、TGF-β1干预组细胞数较对照组增加(P均<0.01)。结论 ET-1、TGF-β1能够促进大鼠肺成纤维细胞CTGF的表达及肺成纤维细胞增殖。
