1、青岛大学硕士学位论文卵巢癌肿瘤干细胞对顺铂和盐霉素的药物敏感性研究姓名:刘静申请学位级别:硕士专业:妇产科学指导教师:纪新强20120610卵巢癌肿瘤干细胞对顺铂和盐霉素的药物敏感性研究摘要目的检测卵巢癌干细胞对顺铂、盐霉素的药物敏感性,并比较两者对卵巢癌干细胞的杀伤作用。方法采用无血清悬浮培养法从人卵巢癌细胞株SKOV-3中分离肿瘤干细胞并采用流式细胞技术检测干细胞标志性因子CD44。人卵巢癌SKOV-3细胞及人卵巢癌干细胞经盐霉素、顺铂作用48h后采用CCK一8比色法检测细胞存活率,计算半数致死量
2、(IC翮)。取第48小时时间点的半数抑制浓度作用于悬浮培养的第5代悬浮细胞48h后,收集药物生存细胞(DSC),采用RT—PCR技术检测DSC的三磷酸腺苷结合转运蛋白B1(ABCBI)基因及三磷酸腺苷结合转运蛋白G2(ABCG2)基因的转录水平。结果无血清悬浮培养法富集的人卵巢癌微细胞球高表达CD44抗原。盐霉素、顺铂作用第48小时时间点卵巢癌SKOV-3细胞IC50为(62.50±2.53)、(3.62±0.38)Ilmol/L,卵巢癌干细胞IC50分别为(48.81±2.83)、(3.80_+0.
