Thanks a lot, Jared!!

Thanks a lot!

Beautiful high-res work from the Delacour lab: a basal supracellular ‘actin-star’ network in intestinal villi. With imaging, ablation and myosin perturbations, they support a tissue-level actomyosin tension scaffold— another great companion to our extrusion findings.

Great to see our conclusions align with the beautiful work from @marija-matejcic.bsky.social in the Trepat lab 3D force mapping, Ca²⁺-triggered myosin-IIA meshwork dissolution, and neighbour lamellipodia generating traction. Great synergy, highlighting the role of tension in extrusion regulation.

I feel like this is the most rewarding comment I ever got.

Thanks for highlighting this! My background in fly morphogenesis shaped how I think about tissue forces, their interplay with signaling, and experimental design. An experience I’d wholeheartedly recommend — Drosophila remains a rich source of inspiration, continuing to reveal fundamental concepts.

This is very complementary with the recent preprint of @xaviertrepat.bsky.social and Maria Matejcic using 2D organoids and providing 3D mechanical characterisation of the process

Important story dissecting the mechanism of gut cell extrusion using organoids. Local heterogeneity of tension promotes live extrusion and basal relaxation is sufficient to kick the cell out. Nice combination of optogenetics and live imaging to demonstrate this

Grateful for my time @thecleverslab.bsky.social with @hansclevers.bsky.social to all collaborators @hubrechtinstitute.bsky.social , @amolf-nl.bsky.social & @IHB Basel as well as to MSCA @ec.europa.eu programme for supporting this journey. Couldn’t have done it without the amazing support!

The gut constantly renews itself. Cells keep the tissue under tension, engaging in a tug-of-war. Weaker cells that can’t counter their neighbours’ pull extrude. This maintains mechanical homeostasis, ensuring stability and protecting the intestinal barrier.

Out in @science.org! We found that the intestine doesn’t just push out cells when crowded. Instead, cells are in a mechanical tug-of-war, and weaker ones are extruded. A new view of how our gut keeps its balance and stays healthy.

Brilliant analysis by @JeremyCliffe and also an important read before the Polish elections this weekend.

There is so much at stake.

Möglicherweise ist es sogar hilfreich das zu tun. Wenn diese Plattform ehm. Twitter ersetzt, Informationsaustausch und demokratischen Diskurs ermöglicht, bedeutet es auch dass die Zerstörung einer Institution allein nicht genügt. Es zeut vielmehr von demokratischer Resilienz.
