Implication

Randomized trial reveals ERH's critical role in regulating cell lineage and pluripotency in mammalian preimplantation development, suggesting potential for stem cell research.

Key Points

This research aims to understand how ERH affects cell lineage and pluripotency during early mammalian development.
ERH depletion experiments in human fibroblasts and mouse models to study effects on H3K9me3 landscape and gene activation.
Analyses of cell lineage segregation during preimplantation development and stem cell differentiation.
Assessment of ERH's interaction with RNA-binding proteins to determine its role in chromatin regulation.
ERH depletion reverted the H3K9me3 landscape to an ESC-like state, facilitating iPSC reprogramming.
ERH was essential for proper segregation of inner cell mass and trophectoderm lineages in mouse blastocysts.
During differentiation, ERH silenced naïve and pluripotency genes and transposable elements, highlighting its role in lineage restriction.
