An appropriate Wnt/β-catenin expression level during the remodeling phase is required for improved bone fracture healing in mice
Abstract Accumulating evidence demonstrates that the Wnt/β-catenin signaling pathway plays a dominant role in bone repair. However, the role of Wnt/β-catenin signaling in the remodeling phase during bone fracture healing is currently unknown. In the present study, β-catenin was activated at differen...
