title: Roles of hyaluronan in bone resorption.
abstract: BACKGROUND
  Hyaluronan, an unsulfated glycosaminoglycan, while being closely linked to osteoclast function several years ago, has received little attention lately. Given recent new knowledge of hyaluronan's possible cell binding abilities, it is important to re-examine the role of this polysaccharide in bone homeostasis.
  
  
  CONCLUSIONS
  Previously published data demonstrating a linkage between induction of hyaluronan synthesis and osteoclast-mediated bone resorption are reviewed. Suggestions are made involving the cell binding ability of hyaluronan and its potential to mediate osteoclast binding to bone surfaces and its potential to serve as a diffusion barrier and participate in the sealing zone required for osteoclast-mediated bone resorption.
  
  
  CONCLUSIONS
  This brief article summarizes previous studies linking HA to bone resorption and suggests roles for hyaluronan in the process of bone resorption.
