osâ²teÂ·oÂ·blasâ²tic adj. osteoblast. a bone-forming cell that is derived from the embryonic mesenchyme and, during the early development of the skeleton, differentiates from a fibroblast to function in the formation of bone tissue. Osteoblasts synthesize the collagen and glycoproteins to form the osteoid matrix and, with growth, develop into osteocytes.
They produce calcium and phosphate mineral deposits that form a very dense, hard shell around a bone fracture. The shell is known as a bone callus and lasts for three to four months. Osteoclasts break down the mineral deposits from the osteoblasts by releasing acid and collagenase enzymes. The broken down material is then released into the bloodstream. The process of bone repair takes months. Osteoblasts and osteoclasts continually work to rebuild fractured bone until it is completely healed.
