Samples
12 samples: 12 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)
We profiled the single-cell transcriptomic effects of LOX (lysyl oxidase) knockdown on MCF10DCIS.com human breast tumor cells and on CD11b+ tumor-associated myeloid cells in an aged-microenvironment xenograft model. GFP-reporting MCF10DCIS.com cells transduced with either pLKO empty-vector (control) or pLKO-LOX shRNA were seeded onto decellularized/delipidized breast dECM scaffolds derived from aged C57BL/6 mice, cultured for 12 days, and implanted bilaterally into Rag1-/- (B6.129S7-Rag1tm1Mom/J) host mice (right flank = pLKO ctrl, left flank = shLOX, matched within-mouse pairing).

Tumors grew for 7 weeks. Three biological replicate pairs (n=3 pLKO + n=3 shLOX, from 3 host mice) were selected for Parse Biosciences Evercode WT v2 single-cell RNA-seq. Each tumor was dissociated and split into a CD11b- tumor-cell fraction and a CD11b+ tumor-associated myeloid fraction, yielding 12 biological samples total (6 tumor + 6 immune). All 12 samples were combinatorially barcoded together and split into 8 sublibraries. Deposited FASTQs are per-biological-sample read groups: after split-pipe v1.0.6p combinatorial demultiplexing, reads were partitioned by assigned sample identity and concatenated across all 8 sublibraries and both sequencing runs, producing one R1/R2 pair per biological sample.

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 GSE333415_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 PRJNA1471051 and SRA study SRP704119. Searching any of these in the dataset finder brings you back here.

Study design
12 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 12 sample titles: 12 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.
