Mean counts of CD3+, CD4+, and CD8+ T cells, CD22+ B cells, CD38+ plasma cells, CD68+ macrophages, and the integrated optical density (IOD) of matrix metalloproteinase-1 (MMP-1) and granzyme B7 in synovial tissue derived from cartilage-pannus junction (CPJ) and suprapatellar pouch (non-CPJ) from patients with rheumatoid arthritis, and measured by computer assisted digital image analysing. Results are shown as means (SEM)
