| Research Abstract |
Purpose : Wnt signaling has many critical roles in development and also Protein kinase C (PKC) family plays key roles in the signal transduction pathways within the cell. The function of both Wnt and PKC signaling during tooth development remains unknown. Wnt is known to activate some different pathways and PKC is thought to be involved in the Wnt signaling pathway. In this study, we examined both Wnt and PKC signaling pathway involved in tooth germ development. Methods : We stained serial paraffin sections with an antibody against Wnt gene family, beta-catenin and PKC isoforms by using immunohistochemical methods and we performed in situ hybridization by using Wnt genes and beta-catenin as probes. Results : In mouse embryo at days 16.5 post-coitum, we observed Wnt proteins, beta-catenin and PKC isoforms were expressed in tooth germ by immunohistochemical analysis. Beta-catenin was localized in tooth germ and also the localization of beta-catenin transcript was overlapped with that of Wnt genes. Conclusions : Thus this study clearly indicates that Wnt/protein kinase C signaling pathway are involved in tooth germ development in mice. *This study was supported by Grants-in-Aid for Scientific Research (No.19592136).
