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)
The spatiotemporal regulation of morphogenetic signals, along with their interaction with local tissue mechanics, guides morphogenesis and determines the shape and form of the embryo (Valet et al., 2022 PMID: 34754086; Pfeifer et al., 2024 PMID: 38181658). However, how these signals precisely integrate into developmental circuits remains poorly understood.

Here, we took advantage of a light-inducible strategy (De Santis et al., 2021 PMID: 34799555) to induce BMP4 signaling with precise spatial coordinates to study epiblast symmetry breaking and its interplay with tissue mechanics at the onset of gastrulation. Light-controlled BMP4 induced SMAD1-5 phosphorylation, resulting in the differentiation of extra-embryonic amnion cells and relied on a tension-dependent induction of the WNT (Muncie et al., 2020 PMID: 33207224) and NODAL pathways for mesoderm and endoderm differentiation. In micropattern gastruloids (Warmflash et al., 2014), tissue tension signals through YAP1 (Totaro et al., 2018, PMID: 30050119). In response to BMP4 stimulation, YAP1 localizes to the nucleus where it represses WNT3 mRNA (Estras et al., 2017, PMID: 29269485), thereby regulating the induction of the three germ layers. Based on these findings, we developed a new mathematical model that integrates tissue mechanics into morphogen dynamics, quantitatively explaining cellular and tissue-scale responses to BMP4 signaling. In all, light induction of the morphogen BMP4 in human embryo models unveiled how embryonic patterning is organized in relation to specific tissue architecture and mechanics at the onset of gastrulation.

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 GSE275856_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1153376 and SRA study SRP529091. Searching any of these in the dataset finder brings you back here.
