Abstract
Abstract Trophoblast lineages are essential for placental development and play indispensable roles in mammalian development. However, the regulatory mechanisms governing trophoblast lineage specification, particularly trophectoderm formation, remain elusive. Here, we show that transient overexpression of the transcription factor Cebpa in mouse pluripotent stem cells efficiently generates trophectoderm-like cells that recapitulate key transcriptional features of trophectoderm. These trophectoderm-like cells can be further induced to form trophoblast organoids and exhibit developmental competence to generate all trophoblast lineages in vitro. Mechanistically, Cebpa overexpression drives extensive epigenetic reprogramming toward a trophectoderm-like state, including global remodeling of chromatin accessibility and coordinated changes in H3K4me3 and H3K27me3 histone modifications. CUT&RUN analyses further reveal binding of CEBPA to multiple trophectoderm-specific enhancers. Together, our findings identify Cebpa as a potent inducer of trophectoderm potential and establish a new platform for modeling trophectoderm lineage specification in vitro.
