摘要: 目的探讨肺腺癌A549细胞株的体外生长特性.方法体外培养肺腺癌A549细胞株,用免疫组化检测肺癌标记物及Brdu表达;取第1代培养后1 d、11 d、13 d 3个时间点分别计数细胞;MTT检测3个时间点细胞活力变化,并进行统计学分析.结果 4个肺癌标记物免疫组化染色,其中鼠抗人p63蛋白,鼠抗人细胞角蛋白7,鼠抗人甲状腺转录因子染色阳性;Brdu在肺腺癌细胞中部分表达;肺腺癌A549细胞株培养18d,13 d组的细胞数量与1 d组相比,差异有统计学意义(P<0.05);11 d组与1 d组的细胞活力无明显差异,13 d组的细胞活力较1 d组和11 d差异有统计学意义(P<0.05).结论肺腺癌A549细胞株在体外早期处于增殖状态,而20 d时细胞活力明显上升.Abstract: Objective To investigate the growth characteristics of human lung adenocarcinoma cell lines A549 in vitro.Methods A549 cell lines were cultured,and proliferative capacity was detected by immunohistochemistry staining of Brdu marker.On 1 day,18 days,22 days after culture,cell numbers were counted,cell vitality were tested by MTT and statistically analyzed.Results Mouse anti-human p63 protein,mouse anti-human cytokeratin 7,mouse anti-human thyroid transcription factor were positive staining by immunohistochem...
