Abstract In long-established rheumatoid nodules, monocytes continue to be recruited and to migrate from the outer vascular zone toward the palisade and central necrotic area. Maturation of these cells is shown to take place during tissue migration. We found that the great majority of palisade cells express exclusive mononuclear phagocyte phenotypes. Among this mononuclear phagocyte population are many cells that bear the receptor for iC3b (CR3), but few that bear the receptor for C3b (CR1). HLA-D region molecule expression is intense and widespread.
