There are five types of '''bone cells'''. |
|||
*[[Osteoblast]]s - These are commonly called bone-forming cells. They secrete [[osteoid]], which forms the [[bone matrix]]. They also begin [[mineralization]], and are unable to divide. |
|||
*[[Osteocyte]]s - A mature osteoblast which no longer secretes matrix, yet is surrounded by it. Maintains metabolism, and participates in nutrient/waste exchange via blood. Unable to divide. |
|||
*[[Osteoclast]]s - These function in resorption and degradation of existing bone, the opposite of osteoblasts! [[Monocytes]] [[(White blood cells)]] fuse together to create these huge cells, which are concentrated in the [[endosteum]]. |

Although [[osteogenic]] or [[osteoprogenitor cells]] are commonly mentioned in bone literature, these do not appear to be a unique type of cell. Rather, osteoblasts derive from [[mesenchymal cell|mesenchymal stem cells]], which have shown the ability to differentiate into [[chondrocyte]]s and [[adipocyte]]s as well. Adipocytes are worm like substances that live and never move freely around and in the bone structure. |
