Abstract： 目的 观察外源性碱性成纤维细胞生长因子(bFGF)基因转染对放射诱导的C17.2神经干细胞(NSCs)凋亡的抑制作用,为探索治疗放射性脑损伤(RE)的新途径奠定实验基础.方法 以直线加速器照射C17.2 NSCs建立离体放射性损伤模型,流式细胞仪检测凋亡率和坏死率,MTT法检测细胞活性并拟合生存曲线.构建含bFGF片段的真核表达体pcDNA3.1-bFGF质粒后,脂质体法转染C17.2 NSCs,观察转染pcDNA3.1-bFGF质粒后细胞对放射的耐受情况,并与对照组比较.结果 转染pcDNA3.1-bFGF的C17.2 NSCs放射后凋亡率和死亡率均显著低于转染空质粒组和对照组(P＜0.05).结论 外源性bFGF基因转染对放射诱导的C17.2 NSCs凋亡具有明显抑制作用,对RE有潜在的治疗价值.
