Lecture 3A – Dynamic Nature of Bone

Dynamic Nature of Bone

Bone contains four cell types:

1. Osteocytes - mature bone cells that:

• maintain bone matrix and monitor protein and mineral content of

surrounding matrix

• participate in bone repair

2. Osteoblasts (develop into osteocytes)- produce new bone

matrix, a process called osteogenesis or ossification

3. Osteogenic (osteoprogenitor) cells - mesenchymal cells which

divide to produce osteoblasts.
