Fibroblast-derived CCL2 function in skin infection

GSE330279 Mus musculus (mouse) Single-cell RNA-seq 13 samples Submitted 2026/05/11 Platform GPL34328
At a glance

Single-cell RNA-seq · mouse · 13 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
13 samples: 3 × Bulk Control vs 3 × Bulk WT vs 3 × Bulk CCL2KO vs 2 × PDGFRa_Ccl2_skinGroups 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)
This dataset includes bulk RNA-seq, single-cell RNA-seq, and spatial transcriptomic analyses performed to investigate the role of fibroblast-derived CCL2 in cutaneous host defense against Staphylococcus aureus infection. Samples include control and infected mouse skin, as well as fibroblast-specific Ccl2-deficient skin, and were used to define transcriptional, cellular, and spatial changes associated with impaired CCL2 signaling during skin infection.

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 GSE330279_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 PRJNA1463268 and SRA study SRP698376. Searching any of these in the dataset finder brings you back here.

Study design
3 × Bulk Control vs 3 × Bulk WT vs 3 × Bulk CCL2KO vs 2 × PDGFRa_Ccl2_skin

Supports a between-group comparison across 11 samples.

How we read this: 4 replicated groups read from 13 sample titles; they account for 11 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.
