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)
Blood transfusion plays a vital role in modern medicine. However, frequent shortages pose a significant healthcare challenge. Ex vivo manufacturing of red blood cells (RBCs) derived from universal donor pluripotent stem cells is limited by the high cost of recombinant cytokines required for ex vivo erythroid differentiation. Erythropoietin (EPO) signaling through the EPO receptor is indispensable to RBC development, and EPO is one of the most expensive components in erythroid-promoting media.

Here, we use design-build-test cycles to develop highly optimized small molecule-inducible synthetic EPO receptors (synEPORs) which are integrated at a variety of genomic loci using homology-directed repair genome editing. We find that integration of synEPOR at the endogenous EPOR locus in an induced pluripotent stem cell producer line cultured with small molecule yields equivalent erythroid differentiation, transcriptomic changes, and hemoglobin production compared to cells cultured with EPO. Due to the dramatically lower cost of small molecules vs. recombinant cytokines, these efforts eliminate one of the most expensive elements of ex vivo culture media—EPO cytokine. As cytokines dependence is a common barrier to ex vivo cell production, these strategies could improve scalable manufacturing of multiple clinically relevant cell types.

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 GSE285656_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 PRJNA1205380 and SRA study SRP554802. Searching any of these in the dataset finder brings you back here.
