Bone morphogenetic proteins (BMPs) and vascular endothelial growth factor (VEGF) have been reported in many studies to play a major role in the communication between endothelial cells and osteoblasts. The inflammatory reaction and relative hypoxia at the site of bone injury are the first stages of the fracture repair. rhBMP-2 has been used extensively in spinal fusion and reconstruction of maxillofacial bone defects with main complication is the formation of seroma. The aim of this study was to test whether rhBMP-2 regulates the expression of the angiogenic and inflammatory mediators in pre-osteoblasts via generating reactive oxygen species (ROS).
