There are five main types of bone cells in bone tissue. Osteocytes are mature bone cells made from osteoblasts that have made bone tissue around themselves.
Osteoclasts are large cells that break down bone tissue.
They are very important to bone growth, healing, and remodeling. The last type of cells are bone-lining cells. These are made from osteoblasts along the surface of most bones in an adult. Bone-lining cells are thought to regulate the movement of calcium and phosphate into and out of the bone. W.B. Saunders Company.
