Osteoclast is critical in skeletal development and fracture healing,yet the impact and underlying mechanisms of their metabolic state on these processes remain unclear.Here,by using osteoclast-specific small GTPase Rh...
The human skeleton is a multifunctional organ made up of multiple cell types working in concert to maintain bone and mineral homeostasis and to perform critical mechanical and endocrine functions.From the beginning st...
