Hedgehog Coordination of Postnatal Osteoclast and Osteoblast Activities

Abstract

The Hedgehog (Hh) pathway is important for skeletal patterning and morphogenesis during embryonic development. Papers by Ohba et al. and Mak et al. in this edition of Developmental Cell suggest that Hh signaling may exert delicate control over the activities of osteoclasts and osteoblasts, the cell types primarily responsible for bone resorption and formation.
