The transcription factor THAP11 is a general regulator of early embryonic polarization

Acute THAP11 depletion in mouse embryos disrupts all three sequential polarization waves—8-cell-morula TE, E3.5–E4.5 PrE, and E4.5–E5.5 Epi—blocking blastocyst formation, PrE maturation, and Epi lumenogenesis.

• Why it matters: It was unclear whether one factor coordinates polarization across these early developmental stages, which are required for fate decisions and morphogenesis.
• What they did: The authors used a mouse model combining genetic knockout with an inducible degron to deplete THAP11 at specific stages, then assessed polarization outcomes and chromatin accessibility and polarity-program activation.
• The result: THAP11 does not directly regulate pluripotency genes; instead, it promotes chromatin accessibility at polarity gene promoters, enabling stage-specific and conserved activation and sequential timing of polarization.
