Endochondral Osteoblasts (REFBs)


Bn.REFBs.EOCs

Osteoblasts are responsible for deposition of the mineral components of the bone matrix. Osteoblasts attach to the surface of the bone matrix, proliferate, and secrete type I collagen and bone-specific non-collagenous proteins such as osteocalcin. These proteins are crucial for mineralization of the bone matrix. At this stage, the osteoid matrix is mineralized.


Mineralized bone matrix can be stained with alizarin red.
