Bone Abstracts

It is well known that the epidermal growth factor receptor (EGFR), its ligands, and the structurally related receptor ERBB2/neu are expressed in skeletal cells. However, the functions of EGFR ligands in bone cells remain poorly defined. In this study, we employed a transgenic mouse line overexpressing the EGFR ligand amphiregulin (AREG) specifically in osteoblasts under the α1(I)-collagen promoter. AREG-tg mice did not show changes in body weight or gross phenotype. Compa...
