Figure 2From: Transition of healthy to diseased synovial tissue in rheumatoid arthritis is associated with gain of mesenchymal/fibrotic characteristicsE-cadherin staining in healthy and arthritic synovial tissue. Synovial biopsies from (a) healthy human subjects and (c) rheumatoid arthritis patients show positive E-cadherin staining in the lining layer. Relative isotype controls are shown in (b,d). Arrows indicate E-cadherin positive cells from the lining layer.Back to article page
