Outline of Final Research Achievements |
Sema3A has been shown not only to function as a axon guidance molecule but also to affect bone metabolism via sensory nerve innervation into bone. To investigate the function of Sema3A in more detail, glia-specific Sema3AKO mice and neuron-specific Nrp1 KO mice, a receptor for Sema3A, were generated, Analysis of bone tissue from each tissue-specific KO mouse revealed a decrease in bone mass in both tissue-specific KO lines. Inaddition, bone histomorphometry revealed a decrease in the number of osteoclasts in glia-specific KO mice. These results suggest that Sema3A derived from glial cells may also affect bone metabolism and Sema3A may regulate bone metabolism through Nrp1-mediated signals.
