| Outline of Final Research Achievements |
In this study, it was focused on that neurogenesis in the enteric nervous system was observed extremely in c-Kit mutant mice, compared to wildtype mice. After the ablation of myenteric plexus layer with benzalkonium chloride, the new neurons were appeared in the longitudinal muscle layer or the subserosal layer, where normally enteric neurons were not distributed. In addition, they were already differentiated into several neuronal subtypes and formed normal enteric ganglion 3 weeks after the ablation with benzalkonium chloride. The neurogenesis was also enhanced in wildtype mice with administration of imatinib, a c-Kit inhibitor, compared to wildtype mice without administration. From these results, it seems that c-Kit signaling regulates the neurogenesis inhibitory in adult gut.
