Figure 4

TGF-β receptor 1 (TGFBR1) and β-actin (control) protein expression in osteoarthritis (OA) synovial fibroblast (SFBs) (n = 4) and rheumatoid arthritis (RA) SFBs (n = 5) as assessed by SDS-PAGE/western blotting (upper panel). Bars indicate the median optical density of protein bands ± 75th and 25th percentiles relative to the value of the β-actin bands (lower panel). *p ≤ 0.05 compared to OA.
