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

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.

Blocking nuclear receptor Nr4a3 unlocks the senescence barrier to promote direct cardiac reprogrammingScience advances · 2025
Summary (written by the submitters)
Direct cardiac reprogramming of fibroblast to cardiomyocytes represents a potential means of restoring cardiac function following injury. However, aged and adult fibroblast are less efficient for reprogramming compared with neonatal fibroblast. In this study, through the joint analysis of RNAseq and ATACseq, we found that compared with Neo-iCM, cardiac related features were down-regulated with aging, while fibrosis and SASP related genes were significantly up-regulated with aging.
Read the full summary ↓
Single-cell transcriptomics reveals a bifurcated trajectory of aged iCM reprogramming. Then, we screened 51 transcriptomic and epigenomic regulators of the barriers to aged-iCM reprogramming and found that Nuclear receptor subfamily 4 group A member 3 (Nr4a3), an pro-inflammatory transcription factor, induced cellular senescence to inhibit direct reprogramming during aging. Mechanistically, knockdown of Nr4a3 enhanced direct cardiac reprogramming by promoting cardiac gene programs and inhibiting fibrosis pathway and secretes SASP. In addition, knockdown of Nr4a3 promoted human reprogramming in primary ventricular human cardiac fibroblasts (HCFs) and improved heart function after MI.

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 GSE267466_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 PRJNA1111552 and SRA study SRP507630. 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.
