Definition

Osteoprogenitor cells are stem cells located in the bone that have the ability to differentiate into osteoblasts. They play a crucial role in bone growth, repair, and maintenance.

5 Must Know Facts For Your Next Test

3. These cells are essential for the healing of bone fractures.
4. Osteoprogenitor cells are activated during periods of rapid bone growth or repair.
5. They maintain the balance between bone formation and resorption by differentiating as needed.
