| description | The early development of mouse embryos involves a tightly regulated series of lineage specification events. Following implantation, these events include maturation of the pluripotent epiblast and simultaneous establishment of the embryonic axes. Here we report that Zfp281, a transcription factor shown to be required for transitioning cells in culture from naïve to primed states of pluripotency, is essential for mouse embryonic development by regulating epiblast maturation. Transcriptomic analyses of Zfp281 mutant embryos revealed a failure in activating Nodal signaling in the epiblast leading to failure in establishing the anterior-posterior axis, and impaired epiblast maturation. Our study establishes Zfp281 as a critical factor that coordinates transcriptional and epigenetic control of pluripotent epiblast maturation. RNA sequencing analysis was performed in WT and Zfp281KO mouse embryos at E6.5. Genome binding/occupancy profiling of Zfp281 was performed in mouse epiblast stem cells (EpiSCs) by ChIP sequencing. |
