Bone Abstracts

Introduction: Wnt/β-catenin signalling and mechanical loading are able to inhibit adipogenesis and to stimulate osteoblastogenesis of mesenchymal stem cells1,2. The involvement of β-catenin signalling in mechanically induced bone formation has already been shown in vivo using a tibia loading model3. The aim of this study was to investigate the influence of the activation of β-catenin on the osteogenic and adip...

Dysfunctions of Wnt/β-catenin and estrogen receptor signalling resulted in impaired mechanotransduction and bone loss as in osteoporosis. Previous studies demonstrated the interaction of these pathways in mechanotransduction in vitro and in vivo. In this study, the influence of the activation of estrogen receptor and β-catenin signalling on mechanically induced bone formation was investigated in ovariectomized mice. 12-week-old mice were ovariectomi...
