Single-nucleus RNA-seq · human · 48 samples

What it is
Single-nucleus RNA-seqGene activity measured in individual nuclei (used when whole cells are hard to isolate, for example from frozen tissue). Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.
Organism
Homo sapiens (human)
Samples
48 samples: 20 conditions, mostly in duplicateGroups 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)
In development, early regionalization steps segregate populations of cells and direct them to specific cell fates. In some instances, this process separates populations of progenitors which eventually become analogous cell types. V2a neurons are a population of excitatory interneurons which are found throughout the hindbrain and spinal cord, two regions of the CNS that arise from different progenitors in development.

Plasticity in the V2a population after spinal cord injury has increased interest in this population as a therapeutic target. We therefore set out to examine how progenitor lineage influences V2a gene regulation and ultimately function. To do so, we differentiated V2a neurons from human stem cells via two distinct progenitor populations. Single nucleus multiomic analysis showed that different V2a lineages were enriched for different transcription factor motifs and differentially expressed hundreds of genes relevant to neuron function, such as axon growth and calcium handling. Attempting to ‘skip’ developmental patterning by induced transcription factor expression yielded a population unlike either developmentally relevant population, highlighting the importance of following developmental steps in establishing cell identities in vitro. Lastly, we employed the CellOracle tool and lentiviral knockdown to perturb lineage-specific gene regulatory networks and identify CREB5 and TCF7L2 as regulators unique to a spinal-like lineage. Overall, this work highlights how small differences in differentiation protocols can influence mature cell fate and uncovers new regulators of neural diversity along the anterior-posterior axis of the central nervous system.

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 GSE282876_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 PRJNA1190924 and SRA study SRP547755. Searching any of these in the dataset finder brings you back here.
