Project Description
We have discovered that neuroectoderm enhancers (but not mesodermal or endodermal ones) are primed by chromatin accessibility and hypomethylation in mouse embryonic stem cells (Argelaguet et al 2019 Nature). In this project we aim to determine if such priming also exist in human embryonic stem cells, and if so, what its function might be in neuroectoderm differentiation in vitro. We will use enhancer annotations from various in vitro differentiation and from in vivo tissue datasets, and map their epigenetic properties in hESCs. We will subsequently manipulate such elements in hESCs by Crispr/Cas9 targeting, and determine the impact of altering their function on neuroectoderm commitment and differentiation in vitro.
