| Outline of Final Research Achievements |
Mesenchymal stem cells (MSCs) have immunosuppressive activity and can differentiate into bone and cartilage; and thus seem ideal for treatment of rheumatoid arthritis (RA) and osteoarthritis (OA). Here, we investigated the immunosuppressive potential, osteogenesis and chondrogenesis potentials of MSCs seeded onto nano-fiber scaffolds (NFs). Healthy donor derived human MSC seeded on NF sheet (NF-MSC) successfully suppressed the collagen induced arthritis of rats. In this context, NFs enhanced the ability of MSCs of cytokines production. Next, in vitro experiment of NF-MSC revealed that NFs stimulated the differentiation of MSCs derived from healthy as well as RA- or OA-patients into osteoblasts, chondrocytes and osteocytes. These data show the possible use of NF-MSCs for the repair of RA-affected joints.
