Brief Summary:This study shows that brain-derived cellular communication network factor 3 (CCN3) is a potent osteoanabolic hormone to enhance bone formation in lactating female mice. CCN3 is produced by KISS1 neurons in the brain, and operates through a unique signaling pathway that interacts with bone-forming osteoblasts leading to increased bone formation.During lactation, the increased calcium demand for milk production leads to considerable bone loss...
