Bone cells known as osteoblasts were recently shown to have a role in controlling the biochemical reactions that generate energy. Researchers have now identified Atf4 as the regulatory gene that ...

Osteoblasts are the cells required for bone synthesis and mineralization, both during the initial formation of bone and during bone remodelling. These cells are present on the bone surface in the form ...

Bone tissue homeostasis is maintained by a balance between bone formation by osteoblasts and bone resorption by osteoclasts. However, when osteoblast function declines with age, bone remodeling ...

Osteoclasts are specialized, multinucleated cells that play a vital role in bone development and regeneration. Credit: vetpathologist/Shutterstock.com The skeleton is ...

Bone cells known as osteoblasts were recently shown to have a role in controlling the biochemical reactions that generate energy via secretion of the molecule osteocalcin. Gerard Karsenty and ...
