What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.

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)
Despite the clinical potential of intestinal organoids as a resource for regenerative cell therapy and bioengineering, the lack of reliable clinical-grade cultures has hampered further development. Here, we report the successful initiation and expansion of patient-derived intestinal organoids under a GMP-compliant protocol. Culture-, cost-, and time-efficiency improvements were achieved with organoid area-based passaging, one well plate culture, and the incorporation of Wnt activating peptide, PG-008.
Read the full summary ↓
The peptide significantly enhanced organoid growth and stabilized patient-patient variability through intestinal stem cell (ISC) enrichment. Single cell RNA sequencing revealed that PG-008 resulted in remarkably pure culture consisting of ISCs and transit amplifying cells, suitable for rapid and consistent expansion. Intriguingly, our GMP-grade intestinal organoids contained LGR5+ ISCs, and injury-induced LGR5- regenerative ISCs, both enriched in peptide culture. Our study establishes clinical-grade intestinal organoids for further application, and a model facilitating in vitro investigations into regenerative stem cell induction and intestinal regeneration.

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 GSE301802_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 PRJNA1287580 and SRA study SRP598958. Searching any of these in the dataset finder brings you back here.
