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
11 samples: 3 × D10 vs 3 × D20 vs 3 × D30 vs 2 × NGroups 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)
Glioma microenvironment contains numerous myeloid cells, including brain-resident microglia and recruited monocytes and macrophages (Mo/Mφ). Previous researches studied these cells collectively and revealed their pro-tumor effects. Yet, little is known about the differences among these myeloid populations. Here we revealed the phenotypic characteristics, spatial variances, and dynamic changes of these relatively heterogeneous cell populations by single-cell sequencing analysis.
Read the full summary ↓
Microglia were pro-inflammatory transiently, and soon skewed to restore the homeostasis of the central nervous system (CNS). Notably, a subset of glioma-associated microglia shared similar trait in a diverse spectrum of neuropathogenesis. Mo/Mφ, on the other hand, were responsible for various tumor-promoting effects, such as angiogenesis, tumor invasion, and immune evasion. Moreover, the Mo/Mφ subsets presented prognostic and classificatory value in clinical application. Conclusively, these results eliminate the long-existing ambiguity about the role of microglia and Mo/Mφ in glioma pathogenesis, and reveal their prognostic and therapeutic value for glioma patients.

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 GSE171081_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 PRJNA718289 and SRA study SRP312606. Searching any of these in the dataset finder brings you back here.

Study design
3 × D10 vs 3 × D20 vs 3 × D30 vs 2 × N

Supports a between-group comparison across 11 samples.

How we read this: 4 replicated groups read from 11 sample titles; they account for 11 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.
