Project description:The transcription factors OCT4 and SOX2 play an essential role in the establishment and maintenance of pluripotent embryonic stem cells (ESCs). Yet, their function in specialized stem cell populations is still poorly understood. Here, we show that the OCT4 and SOX2 work as dimers to regulate the epigenomic landscape of neural crest cells. By isolating primary neural crest cells at a range of developmental stages, we characterized the transcriptomic and epigenomic changes that take place during specification, migration, and early differentiation. Analysis of these datasets revealed that the OCT4/SOX2 dimer promotes an epigenomic signature inherent to the multipotent neural crest. We found that the emergence of this epigenomic state requires the translocation of OCT4/SOX2 to tissue-specific cis-regulatory regions. By examining genome organization during the induction of hESCs into neural crest cells, we observed that the patterns of genomic occupancy of the dimer are modified during cell fate commitment. Dimer translocation is guided by neural crest-specific pioneer transcription factors, which physically interact with the OCT4/SOX to modify their genomic targets. Our results demonstrate how the ESC pluripotency program is repurposed in specialized stem cells to control chromatin organization and define the developmental potential of embryonic progenitors.

Project description:Schwann cell precursors (SCPs) are nerve-associated progenitors that can generate myelinating and non-myelinating Schwann cells but also are multipotent like the neural crest cells from which they originate. SCPs are omnipresent along outgrowing peripheral nerves throughout the body of vertebrate embryos. By using single-cell transcriptomics to generate a gene expression atlas of the entire neural crest lineage, we show that early SCPs and late migratory crest cells have similar transcriptional profiles characterized by a multipotent "hub" state containing cells biased towards traditional neural crest fates. SCPs keep diverging from the neural crest after being primed towards terminal Schwann cell and other fates, with different subtypes residing in distinct anatomical locations. Functional experiments using CRISPR-Cas9 loss-of-function further show that knock-out of the common "hub" gene Sox8 causes defects in neural crest-derived cells along peripheral nerves by facilitating differentiation of SCPs towards sympathoadrenal fates. Finally, specific tumour populations found in melanoma, neurofibroma and neuroblastoma map to different stages of SCP/Schwann cell development. Overall, SCPs resemble migrating neural crest cells that maintain multipotency and become transcriptionally primed toward distinct lineages.
