Objective: To investigate the chemotaxis of human adipose tissue derived mesenchymal stem cell (hATMSC) to human cervical cancer cells and to provide experimental basis for the development of hAT-MSC as a target vehicle for the treatment of cervical cancer. Methods: Primary hATMSC from subcutaneous fat of patients undergoing cesarean section was isolated. hATMSC was induced by osteogenic and adipogenic dif-ferentiation medium, and using Alkaline Phosphatase, Oil Red O staining respectively to verify the differentiative capacity. The expression of surface antigen and OCT-4 mRNA were detected by flow cytometry and qRT-PCR, respectively. The migration ability of hATMSC to cervical cancer squamous cells SiHa, MS751, C33-A, CaSki and adenocarcinoma cell Hela was detected by Transwell assay. Results: Having been incubated in osteogenic and adipogenic differentiation medium for 14 days, hATMSC was positive by Alkaline Phosphatase and Oil Red O staining. The hATMSC was positive for CD90, CD44, CD105 and HLA-ABC, but negative for CD34, CD45, HLA-DR. OCT-4 mRNA was highly expressed in hATMSC. hATMSC had high motility to migrate to cervical cancer cells, and the migration to C33-A was the strongest among them. Conclusion: hATMSC was success-fully isolated and cultured, with the characteristics of stem cells having multi-directional differentiation potential. hATMSC has obvious chemotaxis to different cervical cancer cells, suggesting that hATMSC might be used as a potential carrier for targeting therapy of cervical cancer.%目的:探讨人脂肪组织来源的间充质干细胞(hATMSC)对人宫颈癌细胞的趋化性,为将hATMSC研发成为宫颈癌的靶向治疗载体提供实验依据.方法:从剖宫产产妇的皮下脂肪中分离得到hATMSC.用成骨、成脂分化培养基诱导hATMSC,分别采用碱性磷酸酶、油红染色鉴定其多向分化能力;流式细胞仪检测其表面抗原的表达情况;qRT-PCR法分析细胞中OCT-4 mRNA的表达;Transwell实验检测hATMSC向人宫颈鳞癌细胞SiHa、MS751、C33-A、CaSki以及宫颈腺癌细胞Hela迁移的能力.结果:成骨、成脂诱导14 d后,细胞碱性磷酸酶、油红染色均呈阳性;表面抗原CD90、CD44、CD105、HLA-ABC呈阳性表达,而CD34、CD45和HLA-DR呈阴性表达;细胞中OCT-4 mRNA呈高表达;hATMSC表现出明显的向人宫颈癌细胞迁移的特性,其中向C33-A细胞迁移的能力最强.结论:成功分离培养出hATMSC,细胞具有多向分化潜能的干细胞特性.hATMSC对各种人宫颈癌细胞均有明显的趋化性,提示hATMSC可作为一种潜在的细胞载体用于宫颈癌的靶向治疗.
