摘要:

背景:相比其他组织来源的间充质干细胞,滑膜间充质干细胞有着较强的成软骨特性和克隆能力,因此将是软骨组织工程中最有前景的种子细胞之一。
目的:培养及体外扩增SD大鼠滑膜间充质干细胞,鉴定其多向分化潜能及在添加生长因子后三维立体培养条件下的成软骨能力。
方法:无菌条件下获取SD大鼠滑膜组织,Ⅰ型胶原酶消化法分离大鼠滑膜间充质干细胞。体外扩增、培养,取第3代滑膜间充质干细胞进行吉姆萨、生长曲线测定、成脂诱导、成骨诱导和三维条件下成软骨诱导,成软骨诱导21 d后通过甲苯胺蓝染色、Ⅱ型胶原免疫组化染色及RT-PCR对成软骨诱导后产物进行检测。
结果与结论:获取的大鼠滑膜细胞具有间充质干细胞的特性,滑膜间充质干细胞在体外培养呈成纤维样形态,并维持着多向分化的能力。使用生长因子诱导软骨细胞21 d后,可见软骨样组织,蛋白聚糖和Ⅱ型胶原可以在甲苯胺蓝染色和Ⅱ型胶原免疫组化染色后被检测到。RT-PCR检测结果显示软骨诱导分化后细胞中Ⅱ型胶原和蛋白聚糖mRNA呈阳性表达。提示大鼠来源的滑膜间充质干细胞具有成软骨能力。

Abstract:

BACKGROUND: Compared with other sources of mesenchymal stem cells, synovial-derived mesenchymal stem cells have significant characteristics of chondrogenesis and cloning. Therefore, synovial-derived mesenchymal stem cells are one of the most promising seed cells in cartilage tissue engineering.
OBJECTIVE: To isolate and culture synovial-derived mesenchymal stem cells of Sprague-Dawley rats, identify the multipotential differentiation and the potential ability of chondrogenic differentiation in three-dimensional culture condition.
METHODS: The synovium tissue was harvested from Sprague-Dawley rats. The synovial-derived mesenchymal stem cells were isolated with type Ⅰ collagen enzyme digestion method and cultured in vitro. The passage 3 cells were detected with giemsa staining, the cell cycle, adipogenic and osteogenic differentiation were determined. The passage 3 cells were centrifuged as pellets and cultured in the chondriogenic medium for 21 days. And the pellets were examined by toluidine blue staining, type Ⅱ collagen immunohistochemical staining and RT-PCR.
RESULTS AND CONCLUSION: The mesenchymal stem cells isolated from the synovium tissue of rats have the characteristics of mesenchymal stem cells, and exhibit fibroblast-like morphology after cultured in vitro. The multilineage differentiation potentials were also revealed. After the cell were cultured in chondrogenic medium for 21 days, chondroid tissue was found, type II collagen and aggrecan could be detected positively by toluidine blue staining, type Ⅱ collagen immunohistochemical staining, and expressed by RT-PCR examination. Therefore, synovial mesenchymal stem cells have a chondrogenic differentiation potential.
