title: Does hyaluronan have a role in endothelial cell proliferation of the synovium?
abstract: Hyaluranate (HA) is a major constituent of synovial fluid, but its concentration and molecular size differ in normal and inflamed joints. HA can induce or inhibit angiogenesis depending on both its size and its concentration. Endothelial-cell endocytose-labeled macromolecular HA and HA oligosaccharides and binding studies have identified an HA-specific receptor on the endothelial cell surface (KD, 10(-10) mol/L; approximately 2,000/cell). The molecular weight of HA-binding proteins was found to be 90 to 125, 78, and 46 kd.
