Platelet-derived growth factor and bone morphogenetic protein in the healing of mandibular fractures in rats.
We studied the effects of platelet-derived growth factor-B (PDGF-B) and bone morphogenetic protein-2 (BMP-2) during the healing of mandibular closed fractures in rats by immunohistochemical methods. Unilateral closed fractures were created in the mandibles of thirty 12-week-old rats. ⋯ BMP-2 was related to the differentiation of mesenchymal cells into osteoblasts and chondroblasts. PDGF-B and BMP-2 both have distinct regulatory effects on the healing of fractures.
