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.

Vinculin is a simple adapter protein right? Wrong!

That’s been the prevailing view for the 46 years since it was discovered.

Here we provide a new paradigm and show that vinculin is a complex mechanosensor itself, containing 6 binary switch domains.

The mechanical response of vinculin
Vinculin buffers force via dynamic domain unfolding/refolding under physiological load and lacks a stable head-tail lock.

Integrating theory with experiments to better understand gastrulation flows 🤩

Check out this fascinating #EpithelialMechanics thread by @alex-plum.bsky.social 👇
Which features of tissue flows are most robust and how do they emerge from #EpithelialMechanics?

I’m @alex-plum.bsky.social (@mattiaserra.bsky.social group) and I’ll be sharing some papers on characterizing and controlling avian gastrulation flows.

Cell-cell junction proteins like ZO-1 not only play a critical role in the mechanical interaction between cells, but also participate in the biochemical signalling to coordinate the cell sheet. Check out this review on collective cell migration here to learn more: doi.org/10.1016/j.cd...

Mechanical forces can affect the way tissue grows. Ideally, we want to characterize them without interfering with the processes we are studying. Is there a way to achieve this?

📢 New preprint !
Please check if you are interested in the comparison between 2d and 3d nematic theories 🤔

I show that the 2d description can lead to artefacts on curved surfaces, and I propose a thin film description of nematic shells with full 3d orientation !

This was a funny summer project 😊
