4 Types of Bone Cells

1. Osteoprogenitor Cells

- found within the endosteum membrane

- can differentiate into Osteoblasts

2.Osteoblasts

-use mineral salts and calcium to produce new bone

-can differentiate into Osteocytes

3.Osteocytes

-mature bone cells that maintain bone

4. Osteoclasts

-thought to develop from leukocytes

-functions in breaking down or resorption of bone

-releases calcium

          “Too many Osteoclasts can cause the release of too much

            calcium resulting in Osteoporosis.”

                                   differentiate into                        differentiate into

Osteoprogenitor Cells    =     Osteoblasts     =      Osteocytes

                                               (produce new bone)     (maintain bone)

                         differentiate into

Leukocytes     =     Osteoclasts           

                                 (break down bone)
