摘要
[目的]探讨兔骨髓间充质干细胞(bone mesenchymal stem cells,BMSCs)体外诱导形成软骨细胞的方法,以及转化生长因子-β1(transforming growth factorβ1,TGF-β1)、胰岛素样生长因子-Ⅰ(insulin-like growth factor-Ⅰ,IGF-Ⅰ)和碱性成纤维细胞生长因子(basic fibroblast growth factor,bFGF)之间的相互作用。[方法]对兔骨髓间充质干细胞体外进行原代和传代培养,按加入诱导条件不同分为四组:A组:TGF-β1+bFGF;B组:TGF-β1+IGF-Ⅰ;C组:TGF-β1;D组:空白对照组。3周后分别做四唑盐(methyl thiazolyl tetrazolium,MTT)比色试验、糖胺聚糖(glycosaminoglycan,GAG)检测和免疫组织化学染色。[结果]A、B、C三组Ⅱ型胶原免疫组织化学检测阳性;MTT吸光度值和GAG含量检测结果均为:A组>C组>D组,B组>C组>D组,统计学有显著差异。[结论]兔BMSCs在一定条件下可以诱导成软骨细胞,TGF-β1和IGF-Ⅰ、bFGF在BMSCs向软骨细胞分化和增殖时起协同作用。
