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.

Since #durotaxis was described >25 years ago, most studies report cells migrating from soft → stiff New work from my team at @ub.edu (in collaboration with D. Odde's lab) suggests we may have been missing the point all along... 🔥 Check out our new preprint here 👇 www.biorxiv.org/content/10.6...

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

Be on the lookout for a new paper from the lab: "InterpolAI: Deep learning based optical flow interpolation and restoration of biomedical images for improved 3D tissue mapping" InterpolAI interpolates and restores defective images for enhanced 3D imaging (3D histology, MRI, confocal, ssTEM)

A thread on our recent preprint👇👇👇

The IOP Mechanobiology meeting starts strong with @johannaivaska.bsky.social telling us that cells do not necessarily migrate towards stiff and that nuclear YAP does not necessarily correlate with cell spreading. 💪

🎈New preprint! We study how single cells move up, down and about fibronectin gradients. Experiments by @icfortunato.bsky.social, theory by David Bruckner. Collaboration with @raimonsunyer.bsky.social and @ehannezo.bsky.social 👇https://biorxiv.org/cgi/content/short/2024.12.02.626413v1

Let’s understand collective cell migration by breaking it down to its essential elements! I'm Leone Rossetti, and this is a thread showcasing what we can learn from cells journeying along narrow paths, and from the forces they generate. 1/ #EpithelialMechanics

Mix two motors of opposite polarity with microtubules and they will partition space ! Microtubules will get organized in polar and active barriers, sorting the two motors in separated domains, leading to the emergence of a new type of patterns. #morphogenesis doi.org/10.1073/pnas... (1/n)

Wonderful threat on Traction Force Microscopy by the EMFC! Incidentally, it should be called Traction Microscopy, without ‘Force’, because it measures tractions and not forces. I tried to push for this change for some time, but quickly gave up.
