Summary (written by the submitters)
Stem cell research strives to create diverse types of human brain cells. Given plentiful successes in converting human pluripotent stem cells (hPSCs) into forebrain and midbrain cells, here we focus on generating cells of the human hindbrain, a life-sustaining brain region. This is, in turn, predicated on a developmental roadmap of when and how brain progenitors diversify from one another.

In one model, a common brain progenitor can generate all brain regions. Here our studies of mouse embryos and hPSCs support a different model that as early as gastrulation, two parallel brain progenitors emerge simultaneously: anterior neural ectoderm (forebrain/midbrain progenitor) and posterior neural ectoderm (which forms most of the hindbrain). Expanding on classical studies, we suggest anterior and posterior neural ectoderm are already lineage-committed in vitro and cannot transdifferentiate. Anterior and posterior neural ectoderm have divergent chromatin landscapes, respectively foreshadowing their forebrain versus hindbrain potentials. We differentiated hPSCs into posterior neural ectoderm, and subsequently, hindbrain rhombomere 5/6-specific motor neurons. Anterior and posterior neural ectoderm thus represent two parallel developmental routes to generate forebrain/midbrain vs. hindbrain neurons. Finally, anterior and posterior ectoderm are likely conserved from vertebrates to hemichordates, intimating an ancient neural lineage bifurcation that predated chordates, with implications for nervous system evolution.

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.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE286146_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.

Raw reads on ENA ↗

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 PRJNA1207994 and SRA study SRP556118. Searching any of these in the dataset finder brings you back here.
