摘要
目的 阐明缺氧对人肾间质成纤维细胞血管内皮生长因子(VEGF)表达的影响。方法 原代培养获得人肾间质成纤维细胞,传至第3代用于本实验。细胞经缺氧处理24 h或正常培养后以半定量RT-PCR法检测VEGF mRNA表达量,以流式细胞术检测细胞表面VEGF蛋白含量,以双抗夹心ELISA法检测培养上清VEGF蛋白含量。结果 (1)缺氧能显著增加人肾间质成纤维细胞VEGF mRNA表达(0.34±0.04 vs 0.10±0.01,n=4,P<0.01)。(2)缺氧后细胞表面VEGF蛋白含量较正常对照显著增加(平均荧光强度:1.053±0.055 vs 0.763±0.057,n=4,P<0.01)。(3)缺氧培养细胞上清VEGF含量显著高于正常对照组[(2.009±0.144)mg/L vs(1.647±0.175)mg/L,n=4,P<0.05]。结论 缺氧能诱导人肾间质成纤维细胞表达VEGF,这在缺氧引起的肾脏病理改变中可能起到一定的作用。
