Outline of Final Research Achievements

As an analysis of the factors that is specifically expressed fetal salivaly gland, from head and neck frozen tissue sections of embryonic day 12 old mice, two areas of the oral mucosa and salivary gland were collected using laser microdissection. In addition, the CD133-positive cells from adult submandibular glands were collected by flow-cytometory as salivary gland adult stem cells. And we analyzed embryonic stage salivary gland and salivary gland adult stem cells gene expression profiles using RNA sequence. Using in situ hybridization for high transcription factor of both population, it was confirmed localization in adult submandibular gland and fetal salivaly gland.
