Summary (written by the submitters)
Chromatin priming promotes cell type-specific gene expression, lineage differentiation, and development. The mechanism of chromatin priming has not been well understood. Mouse hematopoietic stem and progenitor cells (HSPCs) lacking the Baf155 subunit of the BAF (BRG1/BRM associated factor) chromatin-remodeler produced a significantly reduced number of mature blood cells, leading to a failure of hematopoietic regeneration upon transplantation and 5-FU injury.
Read the full summary ↓
Baf155 deficient HSPCs, while showing impaired mature blood cell production, generated a higher frequency of myeloid cells with fewer B and CD8+ T cells at homeostasis, supporting a more immune-suppressive tumor microenvironment and enhanced tumor growth. Single-nuclei multi-omic analysis revealed that Baf155 deficient HSPCs failed to establish accessible chromatin and levels of lineage-specific transcripts were considerably lower. Regions that showed a substantial loss in chromatin accessibility were enriched for enhancers and binding motifs for hematopoietic lineage-specific transcription factors. Our study provides a fundamental mechanistic understanding of the role of Baf155 in establishing chromatin priming with functional consequences in regeneration or tumor immunity.

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 GSE240583_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 PRJNA1004272 and SRA study SRP454584. 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.
