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.

Summary (written by the submitters)
Excessive neutrophil infiltration can exacerbate inflammation and tissue damage, contributing to conditions like autoimmune disorders and liver diseases. Mesenchymal stromal cells (MSCs) share homing mechanisms with neutrophils, showing promise for treating such diseases. However, ex vivo expanded MSCs often suffer from reduced homing efficiency due to the loss of essential ligands.

Here, we engineer MSCs with P-selectin and E-selectin targeting peptides, assembling them into bispecific polyvalent structures using DNA self-assembly technology. This modification allows engineered MSCs to compete with chemotactic neutrophils for selectin binding sites on endothelial cells. In a mouse model of acute liver failure, engineered MSCs effectively home to the damaged liver and significantly inhibit excessive neutrophil infiltration. The combination of inhibiting neutrophil infiltration and the MSCs’ inherent therapeutic properties lead to superior therapeutic outcomes. Single cell RNA sequencing reveals that engineered MSCs elevate the levels of Marco_macrophage which possess neutrophil-inhibitory effects. Our study offers a perspective for advancing MSC-based therapies in tissue repair.

This dataset
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 GSE286317_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 PRJNA1208667 and SRA study SRP556389. Searching any of these in the dataset finder brings you back here.
