Bone morphogenetic protein signaling in the murine distraction osteogenesis model.
A murine distraction osteogenesis model was standardized to allow analysis of the molecular pathways associated with postnatal de novo bone formation. The authors examined the presence and expression of Bone Morphogenetic Proteins (BMPs) -2, -3, -4, -6 and -7, and the BMP receptors Alk3 and Alk6 at different stages. Strong signals were detected for BMP-4 at the end of the distraction period and...
متن کاملRecombinant human bone morphogenetic protein-2 suspended in fibrin glue enhances bone formation during distraction osteogenesis in rabbits
INTRODUCTION Bone morphogenetic protein-2 (BMP-2) has high potential for bone formation, but its in vivo effects are unpredictable due to the short life time. This study was designed to evaluate the effects of recombinant human (rh) BMP-2 suspended in fibrin on bone formation during distraction osteogenesis (DO) in rabbits. MATERIAL AND METHODS The in vitro release kinetics of rhBMP-2 suspend...
متن کاملCooperative inhibition of bone morphogenetic protein signaling by Smurf1 and inhibitory Smads.
Smad ubiquitin regulatory factor (Smurf) 1 binds to receptor-regulated Smads for bone morphogenetic proteins (BMPs) Smad1/5 and promotes their degradation. In addition, Smurf1 associates with transforming growth factor-beta type I receptor through the inhibitory Smad (I-Smad) Smad7 and induces their degradation. Herein, we examined whether Smurf1 negatively regulates BMP signaling together with...
متن کاملMolecular signaling in bone fracture healing and distraction osteogenesis.
The process of fracture healing has been described in detail in many histological studies. Recent work has focused on the mechanisms by which growth and differentiation factors regulate the fracture healing process. Rapid progress in skeletal cellular and molecular biology has led to the identification of many signaling molecules associated with the formation of skeletal tissues, including memb...
متن کاملFunction of bone morphogenetic protein signaling during mouse development.
Bone morphogenetic proteins (BMPs) play pleiotropic roles during development and after birth in many different organisms. BMPs are members of TGF-beta superfamily. There are more than 20 members with three type II receptors and three type I receptors. Genetic approaches using the mouse as a model system revealed many of the functions of BMPs. Particularly, results obtained through loss-of-funct...
