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
Homo sapiens (human)
Samples
18 samples: 6 conditions, mostly in triplicateGroups 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)
Human retinal organoids derived from pluripotent stem cells provide an in vitro system to model key aspects of early human retinal development and to investigate mechanisms underlying developmental eye disorders. Congenital eye diseases, such as microphthalmia, anophthalmia and coloboma, arise from disruptions in gene regulatory programs that control retinal progenitor specification and neuronal differentiation.

However, studying these processes in humans is challenging due to limited access to developing retinal tissue. Here we present a temporal bulk RNA sequencing dataset of retinal organoids collected across multiple stages of differentiation (days 0, 35, 60, 90, 120, and 150). These timepoints span early retinal lineage specification through progressive neuronal differentiation and maturation of retinal cell types. The dataset captures dynamic gene expression changes associated with retinal development and provides a transcriptional framework for studying genes implicated in congenital and developmental retinal disorders.

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 GSE326554_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 PRJNA1445881 and SRA study SRP688106. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 18 samples.

How we read this: 6 replicated groups read from 18 sample titles; they account for 18 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.
