One of my dream projects, ever since joining here in Basel, out now in @nature.com : single-cells 🤝 eco-morphological proxies rdcu.be/fiyso How cells and tissues adapt to dietary niches... Thanks and congrats to Antoine, Walter, and all the other co-authors for this great collaboration!! 🙏🥳

Amazing couple of days enjoying & discussing science in the best possible company during the Barcelona meeting of the 'EvoDevOmics Network', funded by @ageinves.bsky.social. Really happy to see how the EvoDevo community in Spain is thriving & fostering a fantastic new generation of PhDs & Postdocs.

Exhausted but extremely happy for the two past days of very exciting Science! The EvoDevOmics Spanish Network gathered together in BCN to discuss about evodevo & omics, lots of great talks, discussions and future collaborations. 🤩 #evodevo

🧵 CTCF is essential for embryonic development, but why has remained unclear. By combining gastruloids with a temporal degron system, we uncovered a surprising dual function — and it changes how we think about CTCF's role in development. 1/8 www.biorxiv.org/content/10.6...

A dual role for CTCF in development

CTCF is an essential DNA binding protein whose absence leads to embryonic lethality. CTCF is primarily known for its role in 3D genome organization where its N-terminal domain interacts with cohesin to anchor chromatin loops. How CTCF facilitates proper embryonic development remains unclear, necessitating temporal control to resolve its stage-specific functions. By combining gastruloids, an in vitro model of embryonic development, with a degron system to rapidly deplete CTCF at defined timepoints, we show that early CTCF depletion impairs early gastruloid morphogenesis. Surprisingly, ATAC-seq and time-resolved RNA-seq revealed that differentiation was unaffected. CTCF binding is strongly enriched at promoters of downregulated genes. Re-expression of a CTCF variant with an N-terminal truncation, incapable of looping, was sufficient to rescue the expression of CTCF-promoter bound genes and the defects in morphogenesis. However, extended culture (up to 168 hours) of gastruloids reconstituted with N-terminal truncated CTCF led to their collapse. Our work shows that CTCF has a dual function in early mammalian development: at early stages CTCF regulates developmentally important genes through promoter binding, while at later stages its looping function is required for correct development. ### Competing Interest Statement The authors have declared no competing interest.
