Abstract
目的 分离肝癌血管内皮细胞.方法采用CD31抗体交联免疫磁珠分选法,并加以优化,对裸小鼠原位人肝癌移植瘤进行血管内皮细胞分选;采用形态学观察、功能实验及RT-PCR等方法进行验证.结果从肝癌组织中分离的细胞呈现典型的内皮细胞形态特征,免疫组化证实内皮细胞标记分子CD31及VE-Cadherin表达阳性,超过95%的阳性分选细胞呈乙酰化低密度脂蛋白摄取实验阳性,RT-PCR示获得的细胞中内皮细胞标记分子CD31、VE-Cadherin及CD146的mRNA含量明显高于分离前.结论采用优化的免疫磁分选法可有效分离纯化肝癌组织中的血管内皮细胞,分离的内皮细胞可用于肝癌血管生成的相关研究。
