Question

Following a bone fracture, the body must repair bone tissue by producing new bone cells. What is the source of these new cells?

Answer 1

Answer:

The periosteum is one source of precursor cells which develop into chondroblasts and osteoblasts that are essential to the healing of bone. Other sources of precursor cells are the bone marrow (when present), endosteum, small blood vessels, and fibroblasts.
