ESRRB facilitates the conversion of Trophoblast-like Stem Cells from induced pluripotent stem cells by directly regulating KRT8 and CDX2 [ChIP-seq]
Ontology highlight
ABSTRACT: Studies on porcine induced pluripotent stem cells (piPSCs) served as a great reference for human clinical research. However, the pluripotency genes network of piPSCs, especially the core transcription factor ESRRB, was currently poor understand. Here, we constructed an overexpressing ESRRB piPSC line (ESRRB piPSCs) in which ESRRB expression was efficiently enhanced. It was found that ESRRB piPSCs showed scattered and flat colonies, moreover, the ESRRB piPSCs showed higher chimeric capacity into trophectoderm than that of CON piPSCs. We also found that ESRRB could directly regulate the expressions of the trophoblast stem cells (TSCs) markers, such as KRT8, KRT18 and CDX2, through binding in their promoter regions. Functional analysis of the mutant domains of ESRRB proved. that the zinc finger domain was indispensable for ESRRB to regulate TSCs markers. Moreover, the regulated process needed the participation of OCT4. Accordingly, ESRRB cooperating with OCT4 promoted TSCs markers to facilitate the conversion from the pluripotent state to trophoblastic-like state. Our results revealed the unique and crucial role of ESRRB in the determination of piPSCs fate and provided opportunities for studying the barriers underlying embryonic and extra-embryonic lineage segregation.
