Mammalian skeletons are formed through two distinct processes, intramembranous ossification and endochondral ossification. During the endochondral ossification, indian hedgehog (Ihh) /parathyroid hormone-related protein (PTHrP) negative-feedback loop regulates the distance between epiphysis and the layer of hypertrophic chondrocytes. Ihh also stimulates bone formation. Based on such knowledge, bioactive molecule-loaded artificial bones are expected to achieve efficient bone regeneration without cell transplantation.
