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.
Osteogenic cells. Osteogenic cells are bipotential stem cells. They are present in two connective tissue layers: (1) the periosteum, which covers the outer surface of bone, and (2) the endosteum, which lines the internal surfaces of bone (e.g., central canals, marrow cavities, and spaces of spongy bone).s a consequence, the cells of the inner layer of the perichondrium differentiate into osteoblasts and start producing bone matrix. Now the perichondrium is considered a periosteum. Soon there is a collar of bone, called subperiosteal bone, surrounding the midsection of the cartilage.
