摘要: 目的:探讨人脐带华通胶间充质干细胞体外分离、培养、鉴定及冻存、复苏的方法。方法收集健康足月新生儿脐带组织,采用组织块贴壁法分离、培养脐带间充质干细胞,流式细胞仪检测细胞表面抗原,将细胞冻存3个月后复苏,鉴定复苏后细胞的特性。结果组织块贴壁法获得脐带间充质干细胞成功率高;细胞表面高表达CD29、CD44、CD90和CD105,不表达造血干细胞表型CD34、CD45等;冻存后再复苏细胞活性高达80%~90%。结论组织块贴壁法可以从人脐带华通胶中较好的分离、培养出间充质干细胞,为干细胞移植实验研究和临床治疗提供了理想的细胞来源。

Abstract: Objective To explore isolating,culturing,identifying,freezing and thawing mesenchymal stem cells(MSCs)approach from Wharton j elly of human umbilical cord.Methods The MSCs were isolated from neonate umbilical cord,cultured by tissue explants adherent method.The surface markers were identified by flow cytometry.Passage cells,frozen 6 months, were thawed,then their biological characteristics were identified.Results MSCs were easily obtained from Wharton j elly of human umbilical cord via the proposed approach of tissue adherence.The flow cytometry analysis showed that MSCs expressed CD29,CD44,CD90 and CD105 positively,but negatively for CD34,CD45.The living cells of MSCs were 80%-90% after having been frozen and the thawed cells had the same characteristics as the previous.Conclusion MSCs can be successfully isolated from Wharton j elly of human umbilical cord by this method. The stem cells derived from Wharton j elly of human umbilical cord may be a novel alternative source of human MSCs for experimental and clinical applications.
