Three main cell types of osseous tissue are osteocytes , osteoblasts and osteoclasts .

Osteoblasts are recognized as bone-forming cells because they are the cells which secrete proteinaceous part of bone matrix (collagen, proteoglycans and glycoproteins). The bone matrix is intercellular space where mineral substances of bones are deposited.

Osteocytes are differentiated mature osteoblasts formed subsequent to these cells are hugely surrounded by bone matrix. Osteocytes have the function of supporting tissue.

Osteoclasts are giant multinucleate cells which remodelate osseous tissue. They are originated from the monocytes and they hold many lisosomes. Osteoblasts secrete enzymes which digest osseous matrix creating canals throughout tissue.
