There are three special types of cells that are found only in the bone. These cell names all start with OSTEO because that is the Greek word for bone. OSTEOCLASTS are large cells that dissolve the bone. They come from the bone marrow and are related to white blood cells.
Four Types of Bone Cells. â¢Osteoprogenitor (osteogenic) cells -- undifferentiated cells. âcan divide to replace themselves & can become osteoblasts. âfound in inner layer of periosteum and endosteum. â¢Osteoblasts -- form matrix & collagen fibers but canât divide. â¢Osteocytes -- the principal cells of bone tissue.
