How do cells navigate up gradients of adhesive proteins? 🤔 Termed "Haptotaxis", this effect is ubiquitous in cell migration, but it's mechanism was poorly understood We show that passive friction directs cells & explains complex trajectories on gradients 👉 www.nature.com/articles/s41...

😍Ready to spend 4 fantastic days here, during @cellmech2025.bsky.social #cellmech2025 !! #Leuven

Happy to share that my PhD has finally taken the shape of a paper! ✨ Huge thanks to all authors, especially @davidbrueckner.bsky.social & @ehannezo.bsky.social for leading the modeling and @raimonsunyer.bsky.social & @xaviertrepat.bsky.social for their invaluable supervision. 🧵👇

In this 2015 Editorial, Alan Hall and Ken Yamada discussed how science community can respond to #reproducibility concerns. rupress.org/jcb/article/... 📕 In Reproducibility and Best Practices in Cell Biology: rupress.org/jcb/collecti...

🔥 Let's warm up for the #cellmech2025 !! Here are some fun facts about the history of the University!👇 🎉 Founded in 1425, KU Leuven is turning 600! That’s older than the printing press. Europe's oldest Catholic university still going strong.

Turns out my university is 575 years old today. Older than coffee and chocolate in Europe. Gaudeamus Igitur 🎉

Collective cell motion has many forms, but rotation is the coolest of them all. I'm @onenimesa.bsky.social , and in this short🧵, I'll highlight some instances of global tissue rotation like this one from @BauschLab

Now published in @natcomms.nature.com! 🥳 👉 rdcu.be/eATn3 We developed image analysis tools to capture the nematic orientation field of 3D tissue surfaces. Tested on epithelial aggregates, zebrafish hearts, myoblasts on spheres & micro-vessels, we combined soft matter physics with exp. biology.

The appearance of large language models caused a drastic shift in the vocabulary of academic writing, according to an analysis in #ScienceAdvances of more than 15 million biomedical abstracts published from 2010 to 2024. Learn more:

Hi I’m @vpmechbio.bsky.social, intrigued by how cells regulate their shape, by means of cytoskeleton and how this influences cellular function. One way to study this mechanism is to impose cells to certain geometric shape. Allow me to welcome you to the world of micropatterning!

Dreaming of a swimming pool? Bacteria are surrounded by water! Water capillary forces organize bacterial colonies into gas, nematic streams, or droplet states. New paper @natphys.nature.com led by Matt Black and Chenyi Fei, with Ned Wingreen and Josh Shaevitz! www.nature.com/articles/s41...

Y aquí va la distribución completa de proyectos: - 2/3 partes de los proyectos tienen 50.000€ o menos por año. Esto no cambia. - La financiación media por proyecto baja ligeramente (2%) respecto al PID2023. - El porcentaje de éxito cae al 46% (49% en el PID2023). La ciencia en España se estanca. 😕

This is so upsetting. Outsourcing writing does not "free up time to do more science" it's just a step further toward becoming the CSO at the top of a managerial pyramid rather than being a scientist

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...

New paper from the lab led by @marija-matejcic.bsky.social ! Supracellular force patterns driving intestinal cell extrusion. 👇

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...

How to turn a layer of fibroblasts into a tulip 🌷? Check out our new pre-print on shape-programmable living surfaces. Led by @pauguillamat.bsky.social‬ www.biorxiv.org/content/10.1...

- A postdoc to work on cancer extravasation (4-year project). - A postdoc help in completing Filopodia-related lab projects (2-year). - Multiple Marie Curie postdoc positions that will open in the fall. - We will open a 5-year position to cover my teaching (70% research and 30% teaching).

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

Are you looking for a postdoc? I will be looking for 2-4 people after the summer to join the lab !! Do not hesitate to reach out and disseminate !!

Almost all Nobel Prizes are awarded for work that is exploratory, or absolutely basic science with no obvious commercial or medical benefit. You cannot predict where advancements come from, so you have to invest in science and scientists. Targeted (corporate) science investment will never do this.

Welcome all (new) followers! Besides our work on probes & biosensors I'd like to share what I know about #Rstats and #DataViz. So I composed a book on data visualization with R & ggplot2 (it's work in progress). Target audience = wet lab scientists. Link: joachimgoedhart.github.io/DataViz-prot...

Science is not a switch that can be flipped on or off. If we do not act now to alter our current trajectory it will undermine our prosperity, our democracy, and our children’s futures for decades to come. You need science. Science needs you. savesciencenow.org

Today is Sant Jordi in Catalonia, a day we celebrate with 🌹 and 📖 Our fellow professor @rsalallonch.bsky.social has made beautiful handmade bookmarks 🔖 for everyone in the lab... each with a unique rose. Bona diada!

1/14 “Epithelial” & “Mesenchymal” aren’t binary categories—they form a spectrum, or better yet, a multidimensional space. This becomes especially clear in collective cell migration, which often depends on a finely tuned degree of “mesenchymal-ness”. #cellbio #devbio #cellmigration

How do hydraulic forces impact critical processes such as tissue integrity, cell fate decisions, and embryo development? Hydraulics studies how fluids move and exert forces. Join me in exploring few articles on hydraulics in #EpithelialMechanics

Es tan sencillo como esto.

Partners in both life and research, the physicists Roger Guimerà and Marta Sales-Pardo recently developed a “machine scientist” algorithm that is proving to be a powerful tool for scientific discovery. (From the archive) buff.ly/0dgSvHG

Unique opportunity to join the CytoMorpho Lab (in Paris ❤️) as a postdoc to work on the self-organization and polarization of reconstituted networks made of microtubules, motors and actin filaments in vitro. Experience required. Please Repost 🙏 thanks !
