<P> Osteoblasts are mononucleate bone - forming cells . They are located on the surface of osteon seams and make a protein mixture known as osteoid , which mineralizes to become bone . The osteoid seam is a narrow region of newly formed organic matrix , not yet mineralized , located on the surface of a bone . Osteoid is primarily composed of Type I collagen . Osteoblasts also manufacture hormones , such as prostaglandins , to act on the bone itself . The osteoblast creates and repairs new bone by actually building around itself . First , the osteoblast puts up collagen fibers . These collagen fibers are used as a framework for the osteoblasts ' work . The osteoblast then deposits calcium phosphate which is hardened by hydroxide and bicarbonate ions . The brand new bone created by the osteoblast is called osteoid . Once the osteoblast is finished working it is actually trapped inside the bone once it hardens . When the osteoblast becomes trapped , it becomes known as an osteocyte . Other osteoblasts remain on the top of the new bone and are used to protect the underlying bone , these become known as lining cells . </P>
