are cells that lay down the protein matrix that becomes bone after mineralization (adding calcium and other minerals) under the influence of Vitamin D. Osteoblast cells form new bone (" bone formation") in the normal process of bone renewal called "remodeling." Formation occurs rapidly during growth in adolescence. It also occurs more rapidly than usual under the influence of progesterone during the luteal phase of the menstrual cycle or from therapy with progesterone, most progestins or parathyroid hormone (which is experimental).
Bone cell capable of synthesizing and secreting new bone matrix as needed; usually found on growing portions of bones.
cells on the surfaces of bone that participate in bone formation.
Cells producing the intercellular matrix in bone.
Cells which form new bone.
Bone-forming cells. PICTURE
Cells associated with bone that are responsible for the new formation of bone in the bone remodeling process.
bone-building cells than create new bone tissue. The B in "blasts" = BUILDING new bone tissue.
Bone-forming cells (see Osteoporosis).
Bone-forming cells which secrete an EXTRACELLULAR MATRIX. HYDROXYAPATITE crystals are then deposited into the matrix to form bone.
Cells that help form bone, usually during orthodontic movement.
