What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart.

Homo sapiens (human)
Samples
10 samples: 10 samples, each with a distinct title — no replicated groupsGroups 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)
The human midbrain-like organoid (hMLO) is a key model system for investigating pathological features of Parkinson’s disease (PD), yet how its molecular landscape relates to cellular vulnerability in PD remains unclear. We performed an in-depth single-cell characterization of our previously established hMLO model up to 150 days in vitro.

Our hMLOs exhibited various physiological cell types and broad topographical patterning that resemble that of human fetal midbrain. We further identified four distinct dopamine-producing neuron (DaN) subtypes whose molecular profiles span a key transcriptomic axis in the selective vulnerability of DaNs in PD. Deletion of PARK7, a highly penetrant PD-causing gene, from hMLOs induced cell type-dependent molecular perturbations in mitochondrial activity and synapse biology, and recapitulated PD pathophysiology including α-synuclein aggregation, Lewy Body-like inclusions and DaN degeneration with extended culture. This study highlights the utility of our hMLO model in manifesting pathological features and cell type-specific vulnerability, enabling mechanistic studies into PD pathophysiology.

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 GSE271115_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1129997 and SRA study SRP517071. Searching any of these in the dataset finder brings you back here.

Study design
10 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 10 sample titles: 10 distinct titles with little repetition. 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.
