文题释义:
紫杉醇:是红豆杉属植物中的一种复杂的次生代谢产物,也是惟一可以促进微管聚合和稳定已聚合微管的药物。同位素示踪表明,紫杉醇只结合到聚合的微管上,不与未聚合的微管蛋白二聚体反应。细胞接触紫杉醇后会在细胞内积累大量的微管,这些微管的积累干扰了细胞的各种功能,特别是使细胞分裂停止于有丝分裂期,阻断了细胞的正常分裂。
细胞表面黏附分子CD133:为具有独特的5个跨膜结构域和2个大的N-糖基化细胞外环的跨膜糖蛋白,其表达的一个显著特点就是随着细胞的分化迅速下调,这使得它成为一个分离和鉴定干细胞和祖细胞的独特分子标志。CD133最初被认为是造血干细胞、内皮祖细胞的标志物,后来CD133被证实其作为一种干细胞标记物在多种实体肿瘤中表达。大量研究发现,CD133+肿瘤细胞与肿瘤发生、侵袭、转移、耐药及复发有着密切的关系。

摘要
背景:
深入进行卵巢癌肿瘤干细胞的研究,有助于以卵巢癌肿瘤干细胞为靶点,改进卵巢癌的治疗策略,提高卵巢癌的生存率。
目的:探讨脐血间充质干细胞联合紫杉醇对卵巢癌A2780细胞增殖、凋亡、侵袭能力的影响。
方法:将人卵巢癌 A2780细胞分为3组:空白对照组(常规培养细胞)、脐血间充质干细胞组(加入1×106个脐血间充质干细胞悬液)、联合组(加入1×106个脐血间充质干细胞悬液的同时加入1 μmol/L紫杉醇溶液250 μL)。采用免疫荧光法检测卵巢癌A2780细胞CD133+抗原表达,流式细胞仪、TUNEL染色法、Transwell小室侵袭实验检测卵巢癌A2780细胞的增殖、凋亡和侵袭能力。
结果与结论:①空白对照组CD133+阳性抗原表达量很多,明显高于脐血间充质干细胞组及联合组,差异有显著性意义(P < 0.05);②联合组细胞增殖能力、侵袭能力明显减弱,凋亡细胞数明显增多,与其他两组比较差异有显著性意义(P < 0.05);③结果表明,脐血间充质干细胞联合紫杉醇能抑制卵巢癌A2780细胞的增殖、侵袭,并促进其凋亡。

Abstract:

BACKGROUND: An intensive study on ovarian cancer A2780 cells contributes to modify treatment strategies targeting ovarian cancer stem cells and enhance survival rate of ovarian cancer patients.
OBJECTIVE: To investigate the effects of umbilical cord blood mesenchymal stem cells (UC-MSCs) transplantation combined with paclitaxel on proliferation, apoptosis, and invasion of A2780 human ovarian cancer cells in vitro.
METHODS: A2780 human ovarian cancer cells were assigned into three groups: blank control group (routine cell culture), UC-MSCs group (addition of suspension containing 1×106 UC-MSCs) and combined treatment group (combined addition of suspension containing 1×106 UC-MSCs and 250 μL of 1 μmol/L paclitaxel solution). CD133+ antigen expression, proliferation, apoptosis, and invasion were determined by immunofluorescent staining, flow cytometry, TUNEL staining, and Transwell chamber invasion assay, respectively.
RESULTS AND CONCLUSON: CD133+ antigen expression in the UC-MSCs group and combined treatment group was significantly decreased compared with the blank control group (P < 0.05). Proliferation and invasion abilities were significantly decreased, while apoptosis cell number was significantly increased in the combined treatment group compared with the other two groups (P < 0.05). These findings indicate that the combined treatment of UC-MSCs transplantation and paclitaxel can inhibit proliferation and invasion and promote apoptosis of A2780 human ovarian cancer cells.
