摘要：

Precursors of osteoclasts seeded on top of a confluent layer of osteoblasts/bone lining cells induced retraction of the latter cells. The (pre)osteoclasts then migrated in the formed cell-free areas and fused to form osteoclast-like cells. Retraction of the osteoblasts/bone lining cells proved to depend on activity of matrix metalloproteinases, and TGF-beta1 prevented the retraction.
