目的:探讨外源性CCN1对大鼠骨髓间充质干细胞(BMSCs)生长和迁移的作用。方法:构建带有绿色荧光蛋白的大鼠CCN1慢病毒载体(Lenti-GFP-CCN1)并感染大鼠BMSCs,筛选最适感染复数(MOI);实验分为空白组、感染Lenti-GFP组和感染Lenti-GFP-CCN1组,倒置荧光显微镜下观察BMSCs感染后荧光表达情况;MTT法检测细胞存活率,划痕愈合实验检测细胞迁移作用。结果:与空白组和阴性对照组相比,Lenti-GFP-CCN1感染大鼠BMSCs后,细胞的存活率未见明显差异;感染组细胞划痕愈合实验的愈合宽度/原宽度值与空白组及阴性对照组相比差异显著(P<0.05)。结论:外源性CCN1对正常大鼠BMSCs存活率无影响,可促进BMSCs迁移。

[ABSTRACT]AIM:Toinvestigatetheroleofcysteine-rich61(Cyr61/CNN1)inproliferationandmigrationof bone marrow mesenchymal stem cells ( BMSCs ) .METHODS: The lentiviral vector carrying CCN 1 ( Lenti-GFP-CCN1 ) was constructed and then transfected into the rat BMSCs .The cells were divided into non-transfection group , transfection group ( transfected with Lenti-GFP-CCN1 ) and negative control group ( Lenti-GFP ) .The fluorescence intensity of the transfected BMSCs was observed under inverted fluorescence microscope .The effects of CCN1 on the proliferation and mi-gration of BMSCs were detected by MTT assay and scratch wound healing assay .RESULTS:The proliferation of BMSCs transfected with Lenti-GFP CCN1 had no significant difference compared with negative control group and control group .The width/thickness ratio of migrated BMSCs in wound healing was significantly higher in Lenti-GFP-CCN1 group than that in negative control group and control group (P<0.05).CONCLUSION:Exogenous CCN1 promotes the migration of BMSCs.
