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.

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.

Klf5 Regulates the Transition from Apical Radial Glia to Intermediate Progenitor Cells in the Developing Mammalian BrainThe Journal of neuroscience : the official journal of the Society for Neuroscience · 2026
Summary (written by the submitters)
Krüppel-like factors (Klfs) are DNA-binding transcriptional factors and regulate multiple physiological features including cell cycle regulation, cell differentiation and tissue organization. Klf2, Klf4 and Klf5 are crucial for the maintenance of pluripotent and somatic stem cells. Here, we show that Klf2, Klf4 and Klf5 are required for the normal neural development in a redundant manner and that depletion of all three genes in neural precursor cells results in impaired activation of Notch signaling and early lethality.
Read the full summary ↓
Klf5 plays a dominant role in the maintenance of neural precursor cell population by suppressing their differentiation and radial migration in the mammalian developing brain. In addition, Klf4 and Klf5 regulate the proliferation of neural precursor cells in opposite directions. Our findings provide new insight on how neural precursor cells are preserved to provide both large number of differentiating cells and a few quiescent neural stem cells.

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 GSE222950_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 PRJNA924273 and SRA study SRP417714. Searching any of these in the dataset finder brings you back here.
