目的 观察人肺癌高转移细胞系SPC-A-1sci的转移相关基因表达,同时验证该细胞系的体内高转移特性.方法 通过Western blot,FICC、IHC等方法检测转移相关基因CD44,OPN,MMP-9,EGFR在高、低转移细胞系间的差异表达;采用尾静脉注射方法观察高、低转移细胞系的转移特性.结果 与低转移细胞系相比,转移促进基因CD44,OPN,MMP-9,EGFR在高转移细胞中的表达均显著上调.体内实验表明,8周时高转移细胞系的肺转移率为100%(12/12),而低转移细胞系的肺转移率仅为16.67%(2/12).结论 人肺癌高转移细胞系SPC-A-1sci在转移相关基因表达和动物体内均表现出典型的高转移特性,为该细胞系的推广应用提供了参考依据
