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.
Organism
Mus musculus (mouse)
Samples
12 samples: 6 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)
The circumvallate papillae (CVP) and foliate papillae (FoP) of the posterior tongue contain taste buds in close proximity to specialized salivary glands, known as von Ebner and minor salivary glands, respectively. The developmental relationship between taste buds and these salivary glands remains largely unexplored. Lineage tracing studies in mice have revealed that Lgr5 marks taste bud stem cells.
Read the full summary ↓
Here, we report single-cell RNA sequencing of the entire CVP and FoP of mice, yielding transcriptional profiles of cells from tongue surface epithelium, taste buds and the associated salivary glands. We unveiled a developmental trajectory in which taste buds, the associated salivary glands and the non-taste tongue surface epithelium originate from a common Lgr5+ cell. We describe long-term organoid culture conditions for these cells and confirm their tripotency at the clonal level in vitro. CVP and FoP harbor chemosensory units consisting of taste bud and salivary gland cells derived from the same parental Lgr5+ stem cell.

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 GSE274014_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 PRJNA1144470 and SRA study SRP524272. Searching any of these in the dataset finder brings you back here.

Study design
6 conditions, mostly in duplicate
c2.9 ×2 c2.10 ×2 CVP_WT ×2 f2.4 ×2 f2.5 ×2 FoP_WT ×2

Supports a between-group comparison across 12 samples.

How we read this: 6 replicated groups read from 12 sample titles; they account for 12 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.
