RESUMO

Synovial cells from patients with rheumatoid arthritis (RA) when grown in vitro in media supplemented with 20% fetal calf serum failed to show any difference in growth rate, life span, uptake of tritiated thymidine or cellular and nuclear characteristics when compared with synovial cells from patients with osteoarthritis or other joint diseases grown similarly in 20% serum enriched medium. There was also no evidence that lymphocytes and/or sera from RA patients were more cytotoxic to autologous synovial cells than sera and/or lymphocytes from OA patients. It is unlikely that antisynovial antibodies or lymphocytes from RA patients act as triggers for synovial damage.
