Research Abstract

We aimed to find the roles of cell communication in bone remodeling. We found an important role of cell communication between osteoclast precursors in osteoclastogenesis via adhesion molecule. Next, we showed the possibility that the gap junctional intercellular communication between osteoblasts and osteocytes controlled osteoclastogenesis via cyclic AMP signaling.
