Abstract:

Cellular replacement therapy for diabetes mellitus has received much attention. In this study we investigated the effect of transplantation of bone marrow-derived mesenchymal stem cells (BM-MSCs) induced into endoderm and early hepatic cells in streptozotocin (STZ)-induced diabetic mice. Mouse BM-MSCs were cultured in the presence of hepatocyte growth factor (HGF) and fibroblast growth factor (FGF-4) for 2 weeks and transplanted into diabetic mice. Blood glucose levels, intraperitoneal glucose tolerance test, serum insulin, body weight and islets histology were analyzed. The results demonstrated that transplantation of syngeneic induced MSCs could reverse STZ-induced diabetes in mice. The treatment of mice with hyperglycemia and islet destruction resulted in the repair of pancreatic islets. Blood glucose levels, intraperitoneal glucose tolerance test, and serum insulin were significantly recovered in induced BM-MSCs (iBM-MSCs) group. In addition, in the iBM-MSCs group the body weight and the number of islets were significantly increased compared to other groups. The results demonstrate that BM-MSCs induced into endoderm and early hepatic cells are suitable candidates for cell-based therapy of diabetes mellitus.
