| Outline of Final Research Achievements |
The Mechanism underlying the anti-inflammatory effect of mesenchymal stem cells (MSCs) has been gradually elucidated. However, the effect of MSCs cultured in serum-free medium has not been clarified. We investigated the difference between MSCs cultured under 10 % fetal bovine serum (FBS) containing medium and serum-free medium of the therapeutic effects in a rat model of renal fibrosis. After 4 days of unilateral ureteral obstruction (UUO) operation, we injected rat MSCs cultured with 10% FBS containing DMEM (10%MSCs) or serum-free medium (SF-MSCs), or PBS only (PBS) through the rat tail vein. As a results, transplantation of SF-MSCs potently inhibited the infiltration of inflammatory cells and the progression of fibrosis compared with 10%MSCs.
