Outline of Final Research Achievements

The neural crest cells (NCCs) originate at the dorsalmost region of the neural tube during the embryonic development of vertebrates. The dysfunction of NCCs is called neurocristopathy. It causes various diseases such as cardiac and intestinal dysfunction, developmental disorders, and congenital malformations as well as tumors.
In this study, we aimed to produce human pluripotent stem cell (hPSC)-derived NCCs as materials for cell therapy against neurocristopathy. In addition, we will generate hPSC-derived three-dimensional small intestinal organoid disease modelings and evaluate the function of hPSC-derived NCs.

Academic Significance and Societal Importance of the Research Achievements

Hirschsprung病も神経堤症の一つで、腸管の動きを制御する腸の神経節細胞の形成不全により、生後数日の間に機能性の腸閉塞症状がみられる。また、Hirschsprung類縁疾患は同様の症状を示すが発症原因は不明であり、治療方法も確立されていない。機能的な三次元小腸オルガノイドを作製することに成功したのは今のところ世界中で本研究室のみであり、細胞治療の原材料としての神経堤細胞の評価を生体内に近い状況おこなうことでヒトに対する細胞治療の実現を加速させることが期待される点で大きな意義のある研究となる。
