| Research Abstract |
To clarify comprehensive morphogenesis of the lingual papillae and establishment of their bio-engineered regeneration, we observed the histology of lingual mucosa and their lingual papillae during morphogenesis in porcine and rat embryos. Moreover, we analyzed about 22,000 mRNA lingual mucosa genes during the morphogenesis of rat embryos. Histological investigations revealed that there were some differences regarding the period of morphogenesis in porcine and rat embryos. This implies that there are some differences of morphogenesis among animal species. We also found that there was one clear fluctuation stage of mRNA expression during the rat morphogenesis. Some of these genes represented specific localizations on lingual tissues. These data would contribute to the identification of the morphogenesis-related genes to clarity the mechanism of the morphogenesis of lingual papillae.
