(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...
