Preclinical and Clinical Studies on the Use of Growth Factors for Bone Repair: A Systematic Review

Bone Morphogenic Proteins and Platelet Rich Plasma, which contains multiple growth factors, have been shown in preclinical and clinical trials to be an effective alternative to autologous bone graft. Bone Morphogenic Proteins have been shown to be effective in fracture non union, and in open tibial fractures. Platelet Rich Plasma has shown promise in preclinical trials and some small clinical trials, however numbers are limited. Bone Morphogenic Proteins have been shown to be superior to Platelet Rich Protein in one trial. Combining these growth factors with tissue engineering techniques is the focus of ongoing research, and through further clinical trials the most effective techniques for enhancing bone healing will be revealed.
