Sialophosphoproteins include osteocalcin.

During the mineralization of an organic matrix (eg enamel), the growing crystals require more space and therefore the extracellular matrix is partially degraded by enzymes.

The basic multicellular unit manages to rebuild its bone segment to an average of four months.

The presence of osteocalcin in urine is considered a positive marker of induced bone formation.

All bone and tooth cells are the product of mesenchymal stem cells.

Bone sialoprotein (BSP) initiates the mineralization process.

Osteocytes are connected to each other by a tight junction.

Carbonate dehydratase catalyses the formation of H₂CO₃ in the osteoclast with the consequent formation of H⁺ and HCO₃^-. Both ions then pass through the channels into the resorption zone.

The enzymes produced by osteoclasts include cathepsins.

Cadherins are also proteins that interact with calcium.
