Frequent question: What cell is most active in osteoporosis?


What cells are involved in osteoporosis?

Which types of bone cells are the culprit for osteoporosis?

The main culprits in bone loss are osteoclasts, which are the cells that break bone down and work in tandem with osteoblasts, which are cells that are responsible for bone formation, to maintain bone volume. But when those osteoclasts over-perform their function, the results are losses in bone density and bone.

How do osteoblasts and osteoclasts work together?

Osteoblast and osteoclast are the two main cells participating in those progresses (Matsuo and Irie, 2008).
