title: Investigating the role of PDGF as a potential drug therapy in bone formation and fracture healing.
abstract: BACKGROUND
  Platelet-derived growth factor (PDGF) has been shown in vivo to increase bone formation and supplement fracture healing, and may have a role as a therapeutic agent in the treatment of bone loss and fracture healing in humans.
  
  
  OBJECTIVE
  A comprehensive review of the recent literature on the effect of PDGF on bone mineral density and fracture healing.
  
  
  METHODS
  In vitro and in vivo evidence was systematically collected using medical search engines MEDLINE/OVID (1950 to March 2008) and EMBASE (1980 to March 2008) databases.
  
  
  CONCLUSIONS
  Evidence to date suggests that PDGF-BB, and to a lesser extent PDGF-AA, may have potential therapeutic use in the treatment of osteoporosis and bone healing in humans. Additionally, by targeting alpha-receptors on osteoblasts, a potential anabolic effect on bone metabolism in humans can be anticipated; however, more research needs to be done to assess the role of beta-receptors in human bone.
