Figure 4From: CD55 deposited on synovial collagen fibers protects from immune complex-mediated arthritis CD55 colocalizes with collagen I and collagen III, but not with ER-TR7 or CD90 in rheumatoid arthritis (RA) synovial tissue. Sections of RA synovial tissue were costained for CD55 (green) and (A) collagen I, (B) collagen III (C) CD90, or (D) ER-TR7 (all red, overlay yellow) and analyzed by confocal microscopy. Shown are representative stainings, magnification 63 x.Back to article page
