Single Cell Expression Atlas

What is Single Cell Expression Atlas?

Single Cell Expression Atlas is an open resource for exploring gene expression at single-cell resolution across species, tissues, and biological conditions.

The service brings together curated public datasets and presents harmonised analysis outputs in a consistent interface for exploration, comparison, and download.

What can you do here?

• Search for a gene and review where it is expressed across experiments.
• Browse experiments by species and metadata attributes.
• Inspect marker genes and cluster-level patterns from re-analysed studies.
• Download metadata and result files for further analysis.

Data curation and re-analysis

Experiments are selected from public archives, curated by domain experts, and processed through a standard analysis workflow to support cross-study comparability.

Some datasets are included as externally analysed submissions and are clearly labelled so users can distinguish them from Atlas re-analysed studies.

Search and visualisation

Single Cell Expression Atlas supports discovery through gene search and metadata-driven exploration, including interactive visualisations of clusters, expression, and marker-gene summaries.
