摘要 目的:采用无血清培养法从肝癌细胞系中分离培养出肝癌干细胞,检测肝癌干细胞的增殖能力及其对化疗药物的耐药性。方法:采用无血清培养法培养肝癌干细胞,采用流式细胞仪检测肝癌干细胞表面标记,检测肝癌干细胞对阿霉素的耐药性。结果:肝癌细胞在无血清培养基中培养1周后能够形成典型的肝癌干细胞球;肝癌干细胞中CD133、CD44、SP的表达水平均较普通肝癌细胞高;肝癌干细胞在普通培养基中生长缓慢,在无血清培养基中具有更强的克隆形成能力,并对阿霉素更耐药。结论:采用无血清培养法能够从肝癌细胞系中培养出具有肿瘤干细胞特性的肝癌干细胞,肝癌干细胞具有较强的耐药性。深入研究肝癌干细胞的特性,有助于寻找有效的肝癌治疗新策略。
