The family of bone morphogenetic proteins.
The family of bone morphogenetic proteins. Bone morphogenetic proteins (BMPs) are secreted signaling molecules belonging to the transforming growth factor-beta (TGF-beta) superfamily of growth factors. The first BMPs were originally identified by their ability to induce ectopic bone formation when implanted under the skin of rodents. In this ectopic overexpression assay, there was a recapitulation of all the events occurring during skeletogenesis. This latter aspect indicated that these molecules could play important roles during development. More than 30 BMPs have been identified to date. The study of their expression pattern as well as the analysis of spontaneously mutated or genetically depleted mice have demonstrated a much broader range of function. These activities are mainly localized at sites of epithelial-mesenchymal interactions, including but not restricted to the skeleton. This review presents our current knowledge about the functions of BMPs during skeleton development as well as in many other biologic processes.
