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.
Osteoclasts are nondividing, motile, multinucleate cells that resorb bone matrix from bone surfaces. They are derived from monocytes, which fuse with one another or with macrophages to form the multinucleate osteoclasts. Some osteoclasts lie in recesses of the bone surface called Howship s lacunae or resorption bays.s a consequence, the cells of the inner layer of the perichondrium differentiate into osteoblasts and start producing bone matrix. Now the perichondrium is considered a periosteum. Soon there is a collar of bone, called subperiosteal bone, surrounding the midsection of the cartilage.
