Question

as the bone matrix calcifies and the secreting cells become walled in, osteoblasts become osteocytes. osteogenic progenitors become osteoclasts. osteoblasts become osteoclasts. osteoclasts become osteocytes.

Explanation:

Osteoblasts are bone - forming cells. When the bone matrix calcifies and the secreting cells (osteoblasts) become walled - in, they transform into osteocytes. Osteoclasts are bone - resorbing cells and osteogenic progenitors can differentiate into osteoblasts, not osteoclasts in this context.

Answer:

osteoblasts become osteocytes.
