Conditional genetics and single-embryo RNA-seq show that SETDB1 extinguishes the transient, retroelement-driven transcriptional programs of the totipotent two-cell state to facilitate the exit from ...
Image of mouse embryos at the 2-cell stage visualised by light microscopy. Two blastomeres (cells) can be seen inside the zona pellucida (a “shell-like” protective outer layer) of each embryo. Credit: ...
