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.

Differential effects of fetal bovine serum and human platelet lysate on mesenchymal stromal cell-mediated support of hematopoietic stem/progenitor cells: a functional and transcriptomic analysisStem cell research & therapy · 2025
Summary (written by the submitters)
To investigate the molecular mechanisms underlying the altered hematopoietic support of mesenchymal stromal cells (MSC) expanded in human platelet lysate (hPL)-supplemented medium, we performed a comprehensive transcriptomic analysis comparing hPL-MSC and fetal bovine serum (FBS)-expanded MSC. MSC from three bone marrow donors were cultured under different adaptation regimens and co-cultured with hematopoietic stem and progenitor cells (HSPC).

Transcriptomic analysis revealed distinct gene expression profiles, with 13% of genes differentially expressed between hPL-MSC and FBS-MSC, impacting cell signaling, extracellular matrix, and chemotaxis. Key pathways, including TGF-beta, PI3K-Akt, and Wnt signaling, were altered, affecting MSC-mediated HSPC expansion. hPL-MSC exhibited increased expression of inhibitory factors and reduced expression of promoters of HSPC proliferation, influencing Notch, TGF-β, JAK/STAT, and Wnt regulation. These findings highlight critical molecular interactions in MSC-HSPC co-culture and provide insights for optimizing xeno-free MSC expansion for hematopoietic applications.

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 GSE294580_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 PRJNA1250525 and SRA study SRP578457. Searching any of these in the dataset finder brings you back here.
