生物信息学资源基本上都是欧洲的EBI的sanger研究所和美国的MIT的broad研究所创造和整理，单细胞领域也不例外：

首先看EBI的sanger研究所

链接是：https://www.ebi.ac.uk/gxa/sc/release-notes.html
最新版： Single Cell Expression Atlas release 15 – March 2021
数据详情：

• Ensembl 99 / Ensembl Genomes 46 / WormBase ParaSite 14 gene annotations.
• This release contains 184 single cell RNA-Seq studies, consisting of 5,890,292 cells, of which 4,104,531 passed our QC from 14 different species.
  

  再看MIT的broad研究所

  链接是：https://singlecell.broadinstitute.org/single_cell
  326 total studies found

  其它单位也有一下零零散散的资源

  比如美国-德克萨斯大学休斯顿健康科学中心的，链接是：https://bioinfo.uth.edu/scrnaseqdb/
  scRNASeqDB database, which contains 36 human single cell gene expression data sets collected from Gene Expression Omnibus (GEO), involving 8910 cells from 174 cell groups.
