Osteoblasts are _____, whereas osteocytes are _____.
a. bone-forming cells; bone-destroying cells
b. mature bone cells; bone-forming cells
c. bone-forming cells; mature bone cells
d. bone-destroying cells; bone forming cells
Answer: c. bone-forming cells; mature bone cells
Osteoblasts are the cells that play an active role in the creation and hardening of bone matrix. They originate from mesenchymal stem cells and mainly participate in the formation of the new bone ECM, which is made up of collagenous fibrils and mineral deposits such as calcium and phosphate.
On the other hand, osteocytes are the mature bone cells that are incarcerated in the bone tissue properly. These are osteoblasts that have been embedded within the bone matrix while performing the various roles of bone staining. Osteocytes are the mature bone cells which play the role of the surveillance of the bone tissue and its metabolic processes like calcium balance as well as bone resorption.
This osteoblast and osteocyte partnership accurately represents the BMP/bone cell life cycle since osteoblasts are the primary manufacturers of new bone tissue, whereas numerous osteoblasts commit to becoming osteocytes to help manage the bones’ existing architecture.
