Tabula Sapiens联盟绘制出人类多器官单细胞转录组图谱。这一研究成果发表在2022年5月13日出版的国际学术期刊《科学》上。

研究人员创建了一个人类参考图集,包括来自24个不同组织和器官的近50万个细胞,其中许多来自同一个捐赠者。这个图集使400多种细胞类型的分子特征、它们在组织间的分布以及组织特有的基因表达变化成为可能。使用来自一个捐赠者的多个组织,研究人员能够识别组织间T细胞的克隆分布,识别B细胞的组织特异性突变率,并分析细胞周期状态和跨组织共享细胞类型的增殖潜力。研究人员发现了细胞类型特异性的RNA剪接,并分析了个体内各组织的情况。

据悉,使用单细胞转录组测序的细胞类型的分子特征正在彻底改变细胞生物学,并使人们对人类器官的生理学有了新的认识。

Abstract: Molecular characterization of cell types using single-cell transcriptome sequencing is revolutionizing cell biology and enabling new insights into the physiology of human organs. We created a human reference atlas comprising nearly 500,000 cells from 24 different tissues and organs, many from the same donor. This atlas enabled molecular characterization of more than 400 cell types, their distribution across tissues, and tissue-specific variation in gene expression. Using multiple tissues from a single donor enabled identification of the clonal distribution of T cells between tissues, identification of the tissue-specific mutation rate in B cells, and analysis of the cell cycle state and proliferative potential of shared cell types across tissues. Cell type–specific RNA splicing was discovered and analyzed across tissues within an individual.
