| Outline of Final Research Achievements |
The main cause of death in diabetes is severe complications in main organs such as cardiovascular systems, brain, kidney and liver. Bone marrow derived mesenchymal stem cells (MSC) are known to exert immune-regulatory functions and tissue regenerations, and are focused as the source of cell-based therapies. In this study, we investigated the therapeutic effects of MSCs on diabetic complications. MSCs were administered to diabetic mice. MSC-conditioned medium (MSC-CM) was also administered to examine the trophic effects of MSCs on organ damages. The curative effects of the MSC and MSC-CM therapies were similar as both ameliorated liver and renal functions, suppressed the excessive expression of proinflammatory cytokines in parenchymal cells and prevented excessive lipid accumulation in hepatocytes. These effects are likely due to various paracrine effects via trophic factors secreted by MSCs. MSC therapy is a powerful tool for repairing diabetic organ damages.
