目的 比较流式细胞仪、免疫磁珠及亲和板结合分离法分选肝癌亚群细胞的效果.方法 原代培养肝细胞癌细胞,分别以流式细胞仪、免疫磁珠及亲和板结合分离法分选c-kit+肝癌细胞,然后使用流式细胞仪鉴定细胞纯度,计算回收率;以台盼蓝检测细胞活力,CCK-8法检测细胞增殖能力,裸鼠移植测其成瘤率,并进行统计学分析.结果 流式细胞仪分选所得到的c-kit+肝癌细胞纯度、回收率最高,与其他两种方法分选所得细胞的相应指标比较,差异有统计学意义(P<0.05);3种方法所得细胞之间的细胞活力、刺激指数、移植成瘤率比较,差异无统计学意义(P>0.05).流式细胞仪分选前后的细胞之间活力、刺激指数比较,差异无统计学意义(P>0.05).结论 流式细胞仪分离法是分离肝癌亚群细胞的较佳方法。
