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
18 samples: 6 conditions, mostly in triplicateGroups 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.
Paper
Clonally expanded, targetable, natural killer-like NKG7 T cells seed the aged spinal cord to disrupt myeloid-dependent wound healingNeuron · 2025
Summary (written by the submitters)
The wound healing ability of the central nervous system declines with aging. Spinal cord injury (SCI) has been increasingly affecting aged individuals, where functional impairment and mortality are highest. However, the aging-dependent mechanisms underpinning tissue damage and repair after SCI remain elusive, limiting effective interventions.
Read the full summary ↓
Here, we hypothesized that changes to the molecular and cellular signatures of the local spinal cord tissue microenvironment across the lifespan might affect spinal wound healing, axonal injury responses and functional recovery. To test this hypothesis, we investigated the molecular and cellular signatures associated with the wound healing response after an experimental SCI in the mouse across the lifespan by conducting single-cell RNAseq (scRNAseq) experiments from the spinal cord of young and aged mice preceding and following a SCI.

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 GSE281205_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 PRJNA1180700 and SRA study SRP543152. Searching any of these in the dataset finder brings you back here.

Study design
6 conditions, mostly in triplicate
Young-naïve, ×3 Young-14dpi, ×3 Young-28dpi, ×3 Old-naïve, ×3 Old-14dpi, ×3 Old-28dpi, ×3

Supports a between-group comparison across 18 samples.

How we read this: 6 replicated groups read from 18 sample titles; they account for 18 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.
