Outline of Research at the Start

これまでにマウス顎下腺の導管結紮・解除による「唾液腺再生マウスモデル」を用いて、唾液腺幹/前駆細胞の維持および唾液腺再生に関わる15の候補遺伝子群を同定している。これら遺伝子の発現状態(発現細胞種・発現時期・組織内局在など)に関するバイオインフォマティクス解析およびin vivo解析を行う。さらに、唾液腺再生に重要と推測される遺伝子をスクリーニングし、発生および唾液腺再生における詳細な役割を明らかにする。

Outline of Final Research Achievements

Regeneration of the glandular cells is important for ameliorating xerostomia. We have previously identified 15 candidate genes based on transcriptome analysis of a model of salivary gland regeneration by conduit ligation. We analyzed the expression of these candidate genes in various cell types using public one-cell RNA-seq data, and found that gene N was highly expressed in neurons. We further applied organ culture to examine the localization of gene N during salivary gland (submandibular gland) development and development, and found that the gene was strongly expressed in the nucleus.

Academic Significance and Societal Importance of the Research Achievements

本研究により,唾液腺幹/前駆細胞の維持・再生に関わる遺伝子の役割が明らかになれば,それらの遺伝子を利用して,①新規唾液腺(腺房細胞)再生療法の開発・人工唾液腺の作製,②口腔乾燥に対する新規薬剤の開発、③口腔乾燥の予防法の開発など,口腔乾燥症に対する新たな知見につながる。
