OCT4-SOX2 dimers reshape the epigenome to promote neural crest multipotency [CUT&RUN]

ABSTRACT: 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.

NANOG-OCT4-SOX2 Regulatory Module in Human Embryonic Stem Cells (dataset 4)

Project description:The transcription factors Nanog, Oct4 and Sox2 are the master regulators of pluripotency in mouse embryonic stem cells (mESCs), however, their functions in human ESCs (hESCs) have not been rigorously defined. Here we show that the requirements for NANOG, OCT4 and SOX2 in hESCs differ from those in mESCs. Both NANOG and OCT4 are required for self-renewal and repress differentiation. OCT4 controls both extraembryonic and epiblast-derived cell fates in a BMP4-dependent manner. OCT4-depleted hESCs commit to trophectoderm and primitive endoderm in the presence of BMP4, but undergo neuroectoderm differentiation in the absence of BMP4. NANOG represses neuroectoderm and neural crest commitment, but has little or no effect on the other lineages. We find that SOX2 is not required for self-renewal because it is redundant with SOX3, which is induced in SOX2-depleted hESCs. Simultaneous depletion of both SOX2 and SOX3 induces differentiation into the primitive streak. Unexpectedly, we identify significant variability in the usage of pluripotency factors by individual hESC lines, suggesting that the pluripotency network is remodelled to support a continuum of developmental states. Our study revises the general view of how NANOG, OCT4 and SOX2 orchestrate self-renewal in hESCs. Total RNA obtained from EF1a-control-, OE-NANOG-, OE-OCT4- or OE-SOX2-transduced hESCs.
