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.

Summary (written by the submitters)
MSCs (mesenchymal stem cells) can promote the structural and functional recovery of lung injury, but most of MSCs do not retain in the injury sites. TFPI (tissue factor pathway inhibitors) can promote stem/progenitor cell migration and homing. The objective of this study was to explore investigate the feasibility and efficacy of TFPI combined therapy with MSCs to alleviate lung injury and the possible mechanism.

rhTFPI or (and) MSCs were administered via tail vein to LPS-induced ALI mice. Lung H&E, coagulation function, TFPI, TNF-α, IL-1β, CXCL12 and CXCR4 in BALF and plasma, 7-day survival rate, and colonization of MSC in lung were observed. Transmembrane migration assay, CCK-8 and EdU assay were used to determine the migration, viability and proliferation of MSCs. RNA sequencing was performed to find differentially expressed genes. The lentivirus transfection technique was used to infect MSCs to overexpession and knockdown TFPI of MSCs. The data demonstrated that rhTFPI could promote cell viability, proliferation and migration of MSCs to improve lung injury. RNA sequence indicated that CXCL12 was in top 40 DEGs and up-regulated after the combination treatment of rhTFPI and MSCs. LPS dampened TFPI, CXCL12/CXCR4 levels in a dose- and time- dependent manner, but can restored by rhTFPI. The level of TFPI expressed by MSCs affected the levels of CXCL12/CXCR4 in MSCs, and migration, proliferation and colonization of MSCs. The results indicated that TFPI may promote the migration, proliferation and colonization of MSCs by regulating CXCL12/CXCR4 signaling pathway.

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 GSE295816_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 PRJNA1256426 and SRA study SRP581794. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 20 samples.

How we read this: 5 replicated groups read from 20 sample titles; they account for 20 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.
