Summary (written by the submitters)
The neural tube (NT) has been a hallmark example of embryonic induction and patterning whereby the notochord induces an organiser, the floorplate, that secretes Sonic Hedgehog (SHH) to pattern the surrounding field of neural progenitors. On the other hand, NT organoids (NTOs) formed from embryonic stem cells (ESCs) undergo spontaneous floorplate formation and patterning in the absence of their normal embryonic inducers.

Understanding how stem cells undergo regulative organiser formation is a central challenge in biology. Here, we investigated the self-organisation of a SHH-expressing floorplate organiser using clonal mouse NTOs. Expression of FOXA2, a floorplate transcription factor, was initially spatially scattered before resolving into multiple clusters. These FOXA2+ clusters underwent competition and physical sorting, resulting in a stable “winning” floorplate. We identified BMP signalling as a key governor of long-range cluster competition. FOXA2+ clusters expressed BMP4 ligand suppressing FOXA2 in receiving cells, while simultaneously expressing the BMP-inhibitor NOGGIN to secure FOXA2+ cluster survival. Genetic mutation of Noggin perturbed the floorplate not only in NTOs but also in vivo at the mid-hindbrain region of the mouse NT. These results demonstrate how the floorplate can form autonomously without its well-known inducer, the notochord, suggesting redundant mechanisms ensuring robustness. Defining molecular pathways that govern organiser self-organisation is critical in harnessing the developmental plasticity of stem cells toward directed tissue engineering.

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 GSE260579_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 PRJNA1082271 and SRA study SRP492577. Searching any of these in the dataset finder brings you back here.
