<P> Osteoblasts are bone cells that are responsible for the formation of new bone . Osteoblasts deposit a collagen matrix and release minerals that combine to make the bone mineral . Unlike the much larger osteoclasts , osteoblasts are much smaller ; they only have one nucleus . Osteoblasts also group to form new bone . Osteoblasts are important because they allow the bones to be made , remodeled , and repaired . The osteoblasts come from the differentiation of osteogenic cells in the tissue that covers the outside of the bone , or the periosteum and the bone marrow . 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 of 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>
