- Bone cell
There are five types of bone cells.
*
Osteoblast s - These are commonly called bone-forming cells. They secreteosteoid , which forms thebone matrix .
*Osteocyte s - A mature osteoblast surrounded by bone matrix.
*Osteoclast s - These function in resorption and degradation of existing bone.
*((Osteogenic))
*((bone-lining))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 stem cells, which have shown the ability to differentiate into
chondrocyte s andadipocyte s as well. Adipocytes are worm like substances that live and never move freely around and in the bone structure.References
