Outline of Final Research Achievements |
Osteoclasts resorb old bone, and osteoblasts make new bone at the resorption site. Therefore, bone tissue is re-formed throughout the life. Although bone formation by osteoblasts is tightly coupled with bone resorption by osteoclasts, the molecular mechanism of the coupling phenomena is unknown. Wnt signaling is an important signal that regulates bone metabolism. In the present study, we showed that (1) Wnt molecules, which osteoclasts and osteoblasts secrete, strictly regulate bone metabolism, (2) osteoclasts regulates osteoblast function through the control of the Wnt signaling, and (3) Wnt signal regulatory agents will become good drugs for osteoporosis treatment.
