Sep 29, 2023 · Bone is a living structure that grows, develops, and is continually modified during life due to the coordinated functions of its cells—osteoblasts, osteocytes, and osteoclasts. The coordinated actions of osteoblasts (bone-forming cells) and osteoclasts (bone-absorbing cells) allow bone tissue to repair itself, after a fracture, without scarring. Because disruption of the regulation of bone-forming osteoblasts results in a variety of bone diseases, a better understanding of the origin of these cells by defining the mechanisms of bone development, remodeling, and regeneration is central to the development of novel therapeutic approaches. Bone tissue is continuously remodeled through the concerted actions of bone cells, which include bone resorption by osteoclasts and bone formation by osteoblasts, …Bone tissue formation.
