(Submitter supplied) Nucleolus is the organelle for ribosome biogenesis and sensing various types of stress. Its role in regulating stem cell fate is unclear. Here, we present multiple lines of evidence that nucleolar stress induced by interfering rRNA biogenesis can drive two-cell stage embryo-like (2C-like) transcriptional program and induce an expanded 2C-like cell population in mouse embryonic stem (mES) cells. Mechanistically, the liquid-liquid phase separation (LLPS) mediated by rRNA and nucleolar proteins maintains the formation of peri-nucleolar heterochromatin (PNH). more...

(Submitter supplied) Transposable elements make up nearly half of mammalian genomes, yet are generally described as ‘junk DNA’ or genome parasites. The LINE1 retrotransposon is the most abundant class and is thought to be deleterious for cells, but it is paradoxically expressed at high levels during early development. Here, we report that LINE1 plays essential roles in mouse embryonic stem (ES) cells and pre-implantation embryos. more...

(Submitter supplied) LIN28 is an RNA binding protein with important roles in early embryo development by interaction with let-7 microRNA precursors or mRNAs in cytoplasm. Here, we showed novel roles of LIN28 within the nucleolus in cultured pluripotent stem cells (PSCs). We found Lin28 deficiency led to activation of the 2-cell (2C)-like transcriptional program and repression of the ES cell program. Mechanistically, LIN28 maintains a peri-nucleolar heterochromatin-residing complex to repress 2C activator Dux via association with NCL and TRIM28. more...

(Submitter supplied) Immediately following fertilisation, the genomes of mammalian embryos undergo extensive reprogramming to generate a totipotent zygote with the capacity to form the entire developing organism and associated extraembryonic tissues. The embryo must also switch from dependence on maternal transcripts to transcribing from its own genome, and is accompanied in mice by rapid and transient upregulation of MERVL transposons and MERVL-driven genes at the 2-cell stage. more...

(Submitter supplied) Mouse embryonic stem cells (mESCs) are not homogenous; a rare subpopulation of cells can sporadically transit into a early-embryonic-like state and exhibits a gene expression program resembling that of the 2-cell (2C) embryo. We identified the maternal factor NELFA as a novel driver of the 2C-like gene expression through multiple mechanisms. We further demonstrate that the entry of mESCs into the 2C-like state is accompanied by epigenetic and metabolic reprogramming, and that perturbation of the metabolic state via a small molecule can promote this cell fate reversion in a NELFA-dependent manner, obviating the need for any genetic manipulation. more...

(Submitter supplied) Pluripotent stem cells have been shown to have unique nuclear properties, e.g., hyperdynamic chromatin and large, condensed nucleoli. However, the contribution of the latter unique nucleolar character to pluripotency has not been well understood. Here, we show fibrillarin (FBL), a critical methyltransferase for ribosomal RNA (rRNA) processing in nucleoli, as one of the proteins highly expressed in pluripotent embryonic stem (ES) cells. more...
