['Rheumatoid arthritis (RA) is a chronic, progressive, and inflammatory autoimmune disease which primarily affects the small arthrodial joints. The aim of this study was to test whether transplantation of mesenchymal stem cells derived from gingival tissue (GMSCs) could ameliorate collagen-induced arthritis (CIA), and to explore the role of the FasL/Fas pathway in the underlying mechanism.', 'DBA/1 mice with collagen II-induced arthritis were treated with GMSCs from the C57BL/6\xa0J mouse, the B6Smn.C3-FasL', 'Systemic infusion of GMSCs can significantly reduce the severity of experimental arthritis, and resume the balance of Th cell subsets. FasL'] Does transplantation of gingiva-derived mesenchymal stem cells ameliorate collagen-induced arthritis?
