Mean semiquantitative scores for the expression of CD3+, CD4+, and CD8+ T cells, CD22+ B cells, CD38+ plasma cells, CD68+ macrophages, CD55+ fibroblast-like synoviocytes, and the expression of mast cells, matrix metalloproteinases MMP-1, MMP-3, MMP-13, and granzyme B7 in synovial tissue derived from cartilage-pannus junction (CPJ) and suprapatellar pouch (non-CPJ) from patients with rheumatoid arthritis. The data are shown as means (SD)
