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。

Abstract:

Objective To explore the effects of adiponectin (Apn) on the proliferation and apoptosis of mesenchymal stem cells (MSCs). Methods Primary rat MSCs were separated and cultured. MSCs were transfected with constructed mouse Apn gene recombinant lentivirus (Lenti-Apn-IRES-EGFP)or control lentivirus (Lenti-IRES-EGFP) and the transfection efficiency was measured. The in vitro proliferation of Gfp-MSCs and Apn-MSCs were detected with the CCK8 kit after transfection. The apoptosis rate was measured with the flow cytometer 12 h after the construction of oxygen and glucose deprivation (OGD) model. Results The proliferation of Apn-MSCs was faster as compared with Gfp-MSCs (P=0.001). The apoptosis rate of Apn-MSCs was lower than that of Gfp-MSCs 12 h after the construction of OGD model (P=0.01). Conclusion Apn can promote the proliferation of MSCs and reduce the apoptosis of MSCs after oxygen and glucose deprivation.
