Single-cell RNA-seq · mouse · 16 samples

What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.
Organism
Mus musculus (mouse)
Samples
16 samples: 4 × heart_CCR8 vs 4 × heart_CCR8+ vs 4 × MLN_CCR8 vs 4 × MLN_CCR8+Groups 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.

Summary (written by the submitters)
We employed single-cell RNA sequencing (scRNA-seq) in a mouse model of MI to gain a detailed analysis of heart and lymphoid Tregs, focusing on their developmental trajectories. Bulk RNA sequencing was used to further characterize the phenotype of CC motif chemokine receptor 8 positive (CCR8+) Tregs in the heart and lymph nodes. scRNA-seq of murine Tregs from the mediastinal lymph node (mLN) and heart after MI identified three Treg populations, one of which was mainly derived from the heart.

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 GSE291962_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 PRJNA1236261 and SRA study SRP570595. Searching any of these in the dataset finder brings you back here.

Study design
4 × heart_CCR8 vs 4 × heart_CCR8+ vs 4 × MLN_CCR8 vs 4 × MLN_CCR8+

Supports a between-group comparison across 16 samples.

How we read this: 4 replicated groups read from 16 sample titles; they account for 16 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.
