They are found on the surface of the bone mineral next to the dissolving bone. OSTEOBLASTS are the cells that form new bone. They also come from the bone marrow and are related to structural cells. They have only one nucleus.

Where are osteoblasts and osteoclasts found?

Osteoblasts, bone lining cells and osteoclasts are present on bone surfaces and are derived from local mesenchymal cells called progenitor cells. Osteocytes permeate the interior of the bone and are produced from the fusion of mononuclear blood-borne precursor cells.

What layer are osteoblasts found?

The inner layer of the periosteum is also referred to as the cambrium. It contains osteoblast cells. Osteoblasts are bone-forming cells. They're very important during the fetal and childhood phases of life when bone tissue is still developing.
