These migrate, expand and contribute to bone formation.Commentary: Bone formation and regeneration requires multiple distinct populations of progeni...

To read the full abstract: Kidney Int 2017;92:599-611Klotho was originally identified as a senescence-related protein because mice carrying hypomorphic Klotho alleles (kl/kl) develop premature aging with low bone turnover and osteoporosis. Primary function of Klotho is to form a specific receptor complex with fibroblast growth factor (FGF) receptor 1 (FGFR1) through which it mediates the bio...

In Brief: The authors use cell tracing approaches in a PRMT5flox/Δ Ctsk-Cre strain to label periosteal stem cells (PSCs) and show that PSCs are not only essential for intramembranous bone formation but also for endochondral bone formation. The study identifies the role of PSC derived indian hedgehog (Ihh) in maintaining growth plate homeostasis and postnatal skeletal growth.Commentary: The skeleton harbors stem cells in three independent ...

Physical activity can reverse age-dependent decline in skeletal muscle, preventing osteopor...
