Bone cell. Coloured scanning electron micrograph (SEM) of a freeze-fractured bone cell (osteocyte,white) surrounded by bone (brown). An osteocyte is called an osteoblast when it is forming bone. It produces osteoid,the organic bone matrix that is a mass of collagen fibres and glycoprotein cement. As soon as osteoid is formed,calcium salts crystallize inside it to form hard,mineralised bone.
