| Outline of Final Research Achievements |
In this study, single-cell RNA sequencing of human three-dimensional organs was carried out with Dr. Camp and Dr. Treutlein others under at Max Planck Institute, Germany.
We identified molecules whose expression could only be seen when multiple cell types were mixed together to generate organoid. By analyzing in detail, we identified signal candidates involved in cell-cell interactions. We performed functional analysis based on the information of this signal candidate molecule and revealed that multiple signal candidates actually contribute to steric intercellular interaction (Camp JG, Sekine K et al, Nature 2017).

| Academic Significance and Societal Importance of the Research Achievements |
本研究によって、生体内で見られる複数の細胞種により構成される立体的な組織における細胞間相互作用の一旦を明らかにし、従来の平面培養における課題を明らかにした。また、本手法によって立体的な細胞間相互作用の新たな解析手法を提示することが出来た。これらの成果は、幹細胞生物学を背景に立体臓器の再構成技術をもつ日本側研究者とシングルセルRNAシークエンス解析の先駆者であるドイツ側研究者の国際共同研究によってはじめて成しえた成果と言える。
