摘要:
目的 建立人角膜基质间充质干细胞(HCS-MSC)体外分离培养、传代和鉴定等方法。方法 无菌条件下,取眼科临床角膜移植术后剩余的供体角膜缘组织,去除上皮和内皮组织,将基质组织切成1mm×2mm的组织块,采用无动物源性血清的间充质干细胞培养液进行组织块贴壁法培养,倒置显微镜下动态观察细胞的生长形态及贴壁状态,将传代培养后的第三代细胞采用流式细胞分析法进行表型鉴定,液氮冷冻保存。结果 采用人角膜缘基质组织块贴壁法培养,于培养后第7天开始向周围呈放射状长出细胞,14天左右长满培养皿,细胞形态呈均一梭形; 传代培养后生长快速,于 2～4天达90%融合; 连续传代3次,其生长特性和形态不变,CD90,CD29和CD105阳性率>95%,CD34和CD-HLA-dr阳性率<3%。结论 采用人角膜缘基质组织可分离培养出间充质干细胞,为角膜组织修复、重建及对抗免疫排斥反应等奠定基础。
Abstract:
Objective To establish a method for isolation,culture,passage,identification and preservation of human corneal stromal mesenchymal stem cells in vitro.Methods After clinical keratoplasty, the residual donor limbal tissue was taken under sterile conditions,the epithelial and endothelial tissues were removed,and the stromal tissue was cut into 1 mm × 2 mm tissue mass.The mesenchymal stem cell culture medium without animal-derived serum was used.The tissue mass was cultured in an adherent manner,and the growth morphology and adherence state of the cells were observeddynamically under an inverted microscope.The third-generation cells were identified by flow cytometry and cryopreserved using liquid nitrogen.Results Human limbal stromal tissue was cultured using tissue mass adherent culture method.On the 7th days,the cells began to radially grow.The culture dish was covered about 14 days after culture,and the cell morphology was uniform as a spindle.The cells were serially passaged 3 times,and their growth characteristics and morphology were unchanged.After subculture,the growth rate was rapid,reaching 90% fusion on 2nd or 4th days.The positive rates of CD90,CD29 and CD105 were all >95%,and the positive rates of CD34 and CD-HLA-dr wereall <3%.Conclusion The results indicated that mesenchymal stemcells can be isolated and cultured from human limbal stromal tissue,whichlays a foundation for corneal tissue repair and reconstruction as well as resistance to immune rejection.
