摘要:
目的 探讨脂联素(Apn)对骨髓间充质干细胞(MSCs)的增殖及凋亡的影响。方法 分离培养原代大鼠MSCs,用构建的小鼠Apn基因重组慢病毒(Lenti-Apn-IRES-EGFP)或对照空载病毒(Lenti-IRES-EGFP)转染MSCs,并测定转染率。转染后用CCK8试剂盒检测Apn-MSCs、Gfp-MSCs在体外的增殖情况,并在缺氧缺糖损伤模型(OGD)12 h后用流式细胞仪检测细胞凋亡率。结果 与对照组比较,Apn-MSCs细胞增殖速度更快(P=0.001)。在OGD 12 h后,Apn-MSCs凋亡率比对照组低(P=0.01)。结论 Apn可以促进MSCs的增殖,并减少缺氧、缺糖损伤后MSCs的凋亡。
