What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)
Samples
22 samples: 22 samples, each with a distinct title — no replicated groupsGroups 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.

A proinflammatory stem cell niche drives myelofibrosis through a targetable galectin-1 axisScience translational medicine · 2024
Summary (written by the submitters)
In a proportion of patients with myeloproliferative neoplasms (MPNs), severe remodelling of the bone marrow (BM) microenvironment develops, with myelofibrosis (MF) and osteosclerosis leading to cytopenias and poor survival. Mesenchymal stromal cells (MSC) have been implicated in MF pathogenesis (Leimkühler, Cell Stem Cell, 2021), including nestin+ (Arranz, Nature, 2014), Gli1+ (Schneider, Cell Stem Cell, 2017) and leptin-receptor+ MSCs (Decker, Nat Cell Bio, 2017).

However, little is known about the cellular subtypes and transcriptional states of fibroblast subtypes in MF, and the key receptor-ligand (R-L) interactions that lead to their activation. Our aim was to build a fully comprehensive atlas of MF BM and clarify the pathological interactions between MPN cells and their stromal environment.

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 GSE228995_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA952518 and SRA study SRP431014. Searching any of these in the dataset finder brings you back here.

Study design
22 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 22 sample titles: 22 distinct titles with little repetition. 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.
