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
10 samples: 4 × FB_monoculture vs 3 × WT_coculture vs 3 × IL13KO_cocultureGroups 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)
Local fibroblast development and densities underpin their role in regulating organ function and inflammation, although it remains unclear how tissue fibroblast topography is controlled in situ. Here we define group 2 innate lymphoid cells (ILC2) as key regulators of fibroblast homeostasis in the pancreas. We show that ILC2 co-localise with Pi16+Dpp4+Ly6c+Il33+ fibroblast progenitors in an interstitial niche of the exocrine pancreas, which demarcates and encapsulates the organ parenchyma.
Read the full summary ↓
ILC2 specifically regulate the expansion of this progenitor population, while paradoxically also restraining differentiated intra-parenchymal Col15a1+ fibroblasts under inflammatory conditions. These homeostatic circuits reinforce fibroblast numbers after injury and set an inflammatory threshold at steady-state. Hence, ILC2-fibroblast dialogue represents a regulatory node that locally orchestrates tissue homeostasis and pathology.

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 GSE248383_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 PRJNA1043649 and SRA study SRP473297. Searching any of these in the dataset finder brings you back here.

Study design
4 × FB_monoculture vs 3 × WT_coculture vs 3 × IL13KO_coculture

Supports a between-group comparison across 10 samples.

How we read this: 3 replicated groups read from 10 sample titles; they account for 10 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.
