GSE277487 Mus musculus (mouse) Single-nucleus RNA-seq 12 samples Submitted 2026/04/24 Platform GPL24247
At a glance

Single-nucleus RNA-seq · mouse · 12 samples

What it is
Single-nucleus RNA-seqGene activity measured in individual nuclei (used when whole cells are hard to isolate, for example from frozen tissue).
Organism
Mus musculus (mouse)
Samples
12 samples: 3 × Mouse_STBI_group1 vs 3 × Mouse_STBI_group2 vs 3 × Mouse_STBI_group3 vs 3 × Mouse_CtrlGroups 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 provides single-nucleus transcriptomic profiles of mouse cortex following controlled cortical impact (CCI)-induced traumatic brain injury (TBI) across multiple time points, including control, 6 hours, 2 days, and 4 days. It enables the investigation of dynamic, cell-type-specific transcriptional responses during injury progression, including immune activation, oligodendrocyte lineage changes, and neuronal responses.

The dataset can be used to explore molecular mechanisms associated with brain edema and to facilitate cross-species comparisons with human TBI, helping to identify conserved and species-specific injury programs.

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 GSE277487_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 PRJNA1162272 and SRA study SRP533280. Searching any of these in the dataset finder brings you back here.

Study design
3 × Mouse_STBI_group1 vs 3 × Mouse_STBI_group2 vs 3 × Mouse_STBI_group3 vs 3 × Mouse_Ctrl

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 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.
