Describe the function of osteoblasts.
What will be an ideal response?
Osteoblasts, or bone-building cells, produce the ECM and then participate in the calcification or mineralization of the matrix, in a process known as bone formation or mineral deposition. Active osteoblasts are found on the surface of newly forming bone. They remove ions of calcium, phosphate, and other minerals from the blood plasma and deposit them within the bone ECM, thus hardening it. In response to bone fracture or the stress of weight-bearing exercise, the osteogenic cells multiply more rapidly and then differentiate to become osteoblasts.
