happy #FluorescenceFriday from the bottom of my (stem cell colony) heart 🫀✨

New Preprint alert!🚨 Super excited to share my postdoc work now on BioRxiv. How does PRC2 loss lead to developmental failures? We combined rapid protein degradation with TLS embryoid models to uncover temporal and lineage-specific dependencies 🧬. Preprint: doi.org/10.64898/2026.04.18.719361

Our latest work on shape-programmable tissues is out in @science.org. By positioning topological defects in cellular nematics, we encode frustrated 2D force fields that relax into predictable 3D shapes. Collaboration with Marino Arroyo’s lab, led by @pauguillamat.bsky.social at @ibecbarcelona.eu.

An egg-cellent use of micropatterning 🙌

Not all eggs are hidden in gardens 🥚🔬 Look how fibroblasts beautifully align along a micropatterned fibronectin "egg" created using photopatterning. There's always room to play in science! (Thanks @oozguc.bsky.social for the inspo 🙌)

Interested in doing a PhD in tumor mechanobiology? At Université Paris-Saclay, the upcoming PhD selection process is open, and I’m looking to put forward a candidate to join my lab. If you’re excited about uncovering how mechanical signals regulate tumor progression, please get in touch!

Sometimes, the only way to build back up is to let everything fall apart. This is certainly true at the cellular level. www.quantamagazine.org/break-it-to-...

Growing tissues can crack, break, and dissociate to form structures that can later withstand immense forces.

How convenient - this tree already comes with ornaments! Get into the holiday spirit with this beautiful cell tree by @oozguc.bsky.social from @ibecbarcelona.eu. This beautiful fusion of science and art was made using our Lamin B1 stem cell line - complete with pink nuclei ornaments!

I am putting together a collection of video-protocols we (will) use in tissue mechanics research🌀 I hope to help consolidate established methods, but also showcase a few up-and-coming ones in our blooming field. Abstract submission by March 2026! Get in touch✨ #JoVETissueMech #ReproducibleTissueMech

For this festive season, I’m sending friends and family something a little different: postcards straight from the microscope. 🔬 Featuring my hiPSC Christmas tree from last year and a hiPSC colony turned into a festive bauble, with wishes for a season that’s festive at every scale. 🎄

You know that sinking feeling 🥶 when it was all going well, but this past month your cells stopped attaching to their protein patterns? Could it be the change of season...? 🫠 Don't know what I mean and it all works? Help a friend! Get your protocol on video🎄🎁 #JoVETissueMech #ReproducibleTissueMech

#LivingArchitectures We put cells and cytoskeleton filaments on the architecture of the musée d'Orsay. www.musee-orsay.fr/fr/agenda/ev... Scientists of the #CytoMorphoLab adapted their protocols to illustrate the questions that keep them awake at night. -> Two shows on the 24th and 25th of January.

Thank you to organisers Alex Dunn, @zevgartner.bsky.social, @adrianjacobo.bsky.social and Matthew Kutys and everyone who joined us for our Workshop on New Technologies for Studying and Reprogramming Development. #BiologistsWorkshops biologists.com/workshops

When #halloween meets #FluorescenceFriday 🎃

📣Announcing the 4th edition of the EMBL‑IBEC Conference on “Engineering Multicellular Systems”, taking place 11–13 March 2026 in Barcelona. Exploring organoids, mechanobiology, embryo models, organ-on-chip systems, multiomics and more. Abstracts open now! events.ibecbarcelona.eu/embl-ibec-co...

1/ 🎉Excited to share our new preprint @vignjeviclab.bsky.social @davidbrueckner.bsky.social : "Self-organization of tumor heterogeneity and plasticity" biorxiv.org/content/10.1... Tumor heterogeneity and plasticity drive metastasis and relapse. How is tumor patterning coordinated? A thread👇

Check out the preprint of my main work in the lab of @xaviertrepat.bsky.social @IBECBarcelona. Many thanks to all the people involved!

New preprint! 🚨 We uncover a slow adaptation to stretch that links star-bundling of keratin filaments with nuclear escape from its keratin cage. Led by @tomgolde.bsky.social‬ 🙌 @IBECBarcelona www.biorxiv.org/content/10.1...

Really just had something like this feeling this afternoon. It’s the high that keeps you coming back for more

On cell extrusion in the #intestine! After 80 years of observations, we finally took a deeper look thanks to 2D #organoids. We report: 3D #forces, #extrusion still only in the villus even without curvature, #lamellipodia generate 3D force.. and more. Have a look! www.biorxiv.org/content/10.1...

Have you ever thought about inflating tissues? Or maybe quickly deflating those inflated tissues? New #EpithelialMechanics pre-print: doi.org/10.1101/2025... 🧵 with pressure control, multiscale buckling, controlled wrinkling

🚨 Second preprint of the week! We uncover the multiscale dynamics of active viscoelastic buckling in epithelia. We harness these mechanical instabilities for synthetic morphogenesis. Led by @onenimesa.bsky.social 🙌. Theory by Marino Arroyo etal. @ibecbarcelona.eu www.biorxiv.org/content/10.1...

New preprint out! We show how cellular nematic order can be harnessed to program tissue-wide force fields and guide 3D shape transformations. The tissue morphogenesis logic, now engineered into living, programmable materials. www.biorxiv.org/content/10.1... #ActiveMatter #TissueEngineering
