Summary (written by the submitters)
Gastrulation is a critical stage of embryonic development during which the three germ layers are established. Deciphering the molecular mechanisms underlying this proces from a protein perspective remains a significant challenge. To address this, we employed a multilayered mass spectrometry-based proteomics approach to investigate the global dynamics of (phospho)protein expression during differentiation of ESCs towards gastruloids – an in vitro model of gastrulation-stage embryogenesis.

Our findings revealed that many proteins exhibited temporal expression with unique expression profiles corresponding to the three germ layers. Additionally, we profiled enhancer interaction landscapes in ESCs and gastruloids using p300 proximity labeling, which revealed numerous gastruloid-specific transcription factors and chromatin remodelers. Subsequent degron based perturbations combined with scRNA-seq revealed a critical role for Zeb2 in regulating mouse and human somitogenesis. Overall, this study provides a rich resource for developmental and synthetic biology communities endeavoring to understand mammalian embryogenesis.

This dataset
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 GSE229024_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA952584 and SRA study SRP431115. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 6 replicated groups read from 14 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.
