What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart.
Organism
Mus musculus (mouse)
Samples
247 samples: 64 conditions, mostly in duplicateGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Dissecting cross-lineage tumourigenesis under p53 inactivation through single-cell multi-omics and spatial transcriptomicsClinical and translational medicine · 2025
Summary (written by the submitters)
For decades, researchers have devoted great efforts to study the tumor suppressor gene Trp53, however, our understanding of Trp53 regulation has never reached either organism-scale or single-cell resolution. We constructed single-cell transcriptomic landscape covering 18 organs of Trp53-/- mice models to explore genetic network transformations in the absence of Trp53.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE217662_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA899905 and SRA study SRP407088. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 133 samples.

How we read this: 64 replicated groups read from 247 sample titles; they account for 133 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
