- [scRNAseq bioc package](https://bioconductor.org/packages/devel/data/experiment/html/scRNAseq.html) Gene-level counts for a collection of public scRNA-seq datasets, provided as SingleCellExperiment objects with cell- and gene-level metadata.
- [human cell atlas database](https://staging.data.humancellatlas.org/)
- [EMBL-EBI atlas](https://www.ebi.ac.uk/gxa/sc/home)
- [PanglaoDB](https://panglaodb.se/) is a database for the scientific community interested in exploration of single cell RNA sequencing experiments from mouse and human. We collect and integrate data from multiple studies and present them through a unified framework.
