title: [Cells of bone tissues].
abstract: Bone cells consist of osteoblasts, osteocytes, and osteoclasts. Osteoblasts secrete collagen and orientate directions of collagen fibrils to form bone lamellae in the bone matrix. Osteocytes are differentiated in the layer of osteoblasts as functionally different cells from the osteoblasts and sink into the bone matrix to form a network of cell processes to monitor the stress added to the bone. Osteoclasts, multinuclear giant cells on the bone, resorb the bone matrix on the bone surface. These three kinds of bone cells functionally cooperate to each others.
