Outline of Final Research Achievements

In this study, we will establish a versatile data analysis method to detect cell types contained in cell populations. In recent years, the single-cell RNA-Seq has been introduced to measure the gene expression level at the single-cell level, and it has become possible to accurately measure the heterogeneity of the cell population. However, it is difficult to identify which data point of single-cell RNA-Seq data corresponds what kind of cell type because the cell type is often unknown in advance. Therefore, in this study, we try to establish a data analysis method to identify the cell type of single-cell RNA-Seq data.

Academic Significance and Societal Importance of the Research Achievements

1細胞RNA-Seqデータ解析において、Celltypingで決定された細胞型ラベルは、その下流のあらゆるデータ解析で利用されるため、Celltypingはその後の研究の進退に関わる重要な解析ステップである。しかしながら、現状のCelltypingの方法は時間がかかり、かつ解析者の事前知識に依存する主観的な作業であった。そのため、このCelltypingを自動的、かつ客観的に行えるための方法論を構築した。本研究の提案手法によるCelltypingは、再生医療・創薬、発生生物学、疾患関連細胞など、1細胞RNA-Seqを利用した生命科学研究全てに貢献する。
