Studies have shown that stem cell treatment is safe and efficacious for the treatment of Rheumatoid Arthritis (RA). Patients with RA will receive a single intravenous infusion and intra-articular injection of cultured allogeneic adult umbilical cord or placental derived mesenchymal stem cells. Patients will be evaluated within one month pre treatment and at 1, 6, 12, 24, 36, and 48 months post treatment for safety and efficacy.
