Nat Med. 2020 Oct;26(10):1583–1592 Abstract: https://pubmed.ncbi.nlm.nih.gov/32807933/In brief: Improved treatments for osteoarthritis and other degenerative joint diseases are urgently needed. This study demonstrates, for the first time, that the synovial microenvironment can be modified to allow resident skeletal stem cells to form hyaline articular cartilage and thereby reg...

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...
