UNLABELLED: HA activates CD44 to stimulate RANKL expression in bone marrow stromal cells. HA stimulation of RANKL is blocked by anti-CD44 antibody and is absent in cells from CD44(-/-) mice. CD44(-/-) mice exhibit thicker cortical bone and a smaller medullary cavity, but indices of bone resorption are not affected. INTRODUCTION: Hyaluronan (HA), the major nonprotein glycosaminoglycan component of the...
