摘要

To investigate the therapeutic effects and mechanism of human bone marrow mesenchymal stem cells(MSC) transplantation in MRL/lpr mice. Human MSCs were expanded ex vivo. MRL/lpr mice were divided into cyclophosphamide (CTX) group, MSC group, CTX+MSC group, and control group. At the age of 16 weeks, the mice in CTX group and MSC+CTX group received intraperitoneal injection of CTX 100mg/kg×2d. 24 hours after injection, the MSCs were transplanted in MSC group and CTX+MSC group through tail vein. Human MSC transplantation is effective treatment for MRL/lpr mice. The regulation of Th1/Th2 balance and inhibition the antibodies of B cells mediated by human MSCs may be the mechanisms of effective treatment.
