ABSTRACT
Objective To investigate the proliferation and differentiation characteristics of fibroblast like synovial cells(FLS)in rheumatoid arthritis(RA)in vitro and the mechanism of the immunosuppressive effect of differentiation inducers, such as all trans retinoid acid(ATRA), ealcitriol [1,25(OH)_2D_3] and dexamethasone(DEX). Methods FLS of knee synovial tissues from RA patients were cultured and identified in vitro in the presence or absence of ATRA, 1,25(OH)_2D_3 and DEX respectively. Synoviocyte proliferation in RA were measured by MTT colorimetrie assay and the survival fraction(SF)of FLS was evaluated. Cell cycle of FLS was observed using fluorescence-activated cell sorting(FCS)method in RA patients. Results The identified synovial cells in patients with RA were FLS(Vimentin and Fibronectin expression was positive), and hadn't been transformed or differentiated to adipocytes and osteoblasts with the three inducers. The SF of all RA-FLS interfered by ATRA, 1,25(OH)_2D_3 and DEX was much lower than that without drugs vehicle group in RA-FLS(P
