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 ...
