Abstract
【目的】 用流式细胞仪(FCM)快速检测外源性血管内皮生长因子基因(VEGF基因)在大鼠原代培养肝细胞转染表达,根据结果优化其转染表达条件?【方法】 以加强型黄色荧光素蛋白(EYFP)为标记,用FCM快速检测重组质粒pIRES-EYFP/VEGF121在大鼠原代培养肝细胞中转染表达,根据结果优化pIRES-EYFP/VEGF121转染表达条件?【结果】 pIRES-EYFP/VEGF121得以成功构建,并转染大鼠原代培养肝细胞;优化的转染表达条件:在细胞数密度0.1×106/mL,质粒孵育时间30 min,质粒与脂质体混合物孵育时间15 min,质粒与脂质体比例为1∶10,转染时间2 h,NAIR-1作转染培养液时,转染效率达17.5%? 【结论】以EYFP为标记, FCM可简便快捷地检测并优化外源性VEGF基因在大鼠原代培养肝细胞转染表达,可为研究VEGF基因修饰大鼠原代培养肝细胞移植和肝基因治疗打基础
