Purpose: To determine whether renal injury induced by ischemia-reperfusion (I/R) could be further improved by mesenchymal stem cells (MSCs) modified with survivin. Materials and Methods: Lentiviral vectors were used to introduce the survivingene into MSCs and the MSCs modified with survivin were transplanted into established mice models of renal I/R injury. Seven days later, serum creatinine (Scr) and blood urea nitrogen (BUN) were measured and the survival of MSCs was determined. Hematoxylin and eosin staining was used to assess renal pathologicalchange. The expressions of hepatocyte growth factor (HGF) and basic fibroblastgrowth factor (bFGF) in kidney tissue were detected by western blot. Results:Mice transplanted with survivin-modified MSCs demonstrated good renal function recovery with Scr and BUN decline close to normal levels and improvementof renal I/R injury repair. Additionally, the survival of transplanted MSCs modified with survivin was enhanced and the expression of HGF and bFGF in kidney tissue was increased. Conclusion: Our results demonstrated that MSCs engineeredto over-express survivin could enhance their therapeutic effect on renal I/R injury in mice, probably via the improved survival ability of MSCs and increasedproduction of protective cytokines in ischemic tissue.
