Synovial tissue from patients with rheumatoid arthritis was enzymatically dissociated, and single cell suspensions were fractionated into subpopulations by centrifugation on continuous Percoll gradients. Five fractions (F1-F5) with densities of 0.991-0.998 gm/ml, 0.998-1.042 gm/ml, 1.042-1.062 gm/ml, 1.062-1.082 gm/ml, and 1.082-1.180 gm/ml, respectively, were prepared. F3 consistently contained the highest number of macrophages, while F2 and F4 contained substantially fewer macrophages. Macrophages present in F2, F3, and F4 were enriched by differential adherence to fibronectin-coated collagen gels. These macrophage-enriched cell preparations were found to be Fc and C3 positive, esterase positive, and peroxidase negative, to stain positively with anti-HLA-DR, anti-Leu-M3, OKM1, and OKM5 monoclonal antibodies, and to show characteristic features of macrophages by electron microscopy. Macrophages from F3 consistently induced neovascularization in rat corneas, while equal numbers of macrophages from F2 and F4 did not. Fibroblastic synovial cells and cells that did not adhere to fibronectin-coated collagen gels did not induce neovascularization. Within the rheumatoid synovium, there appears to be a major subpopulation of macrophages capable of inducing neovascularization, a process vital to the development of the rheumatoid synovial pannus.
