Thank you, Elias! 🙏

Thank you, Nimesh 😊🙏

Single-cell migration along and against confined haptotactic gradients - Nature Physics Haptotaxis was traditionally seen as migration up protein gradients. It is now shown that cells can also oscillate or migrate down the gradient.

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

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.

Stoked to announce that I received a poster award! 🔥😍

Many thanks to the #25EngLife organizers for the amazing meeting!

Leveraging computational modeling to explore epithelial and endothelial cell monolayer mechanobiology Endothelial cells (ENCs) and epithelial cells (EPCs) form monolayers whose barrier function is critical for the maintenance of physiological processes and extremely sensitive to mechanical cues. Compu...

Might be an interesting review on that topic !

Micro Immune Response On-chip (MIRO) models the tumour-stroma interface for immunotherapy testing - Nature Communications Modelling the tumour immune microenvironment in vitro is a valuable tool to test immunotherapy efficiency but capturing its complexity is challenging. Here authors present a fully humanised in vitro p...

1/7: New paper alert! Excited to share our co-first author paper on Micro Immune Response On-chip (MIRO) a model that recreates the tumour-stroma interface for immunotherapy testing! @oriolmb.bsky.social and I wrote this thread to break it down for you. 👇🧵

Cao and colleagues found that the depleted heart tissue regenerates itself in a wave, led by a front of fast-moving, supersized cells and trailed by smaller cells that multiply to produce others. The image above shows the large cells that contain multiple nuclei per cell (magenta). These cells are under more mechanical tension (aqua streaks) than trailing cells, which divide to produce cells with one nucleus each.

Let's look at some cool bilateral cellular flows videos
IMHO: this is a goldmine for #EpithelialMechanics
Movie from Asai et al 2024 shows beautiful counter rotating flows.

Is endothelium a type of epithelium?

I am @icfortunato.bsky.social & I would like to discuss this with a short🧵 focused on cell-cell junctions, specifically adherens junctions.

Force transmission is a master regulator of mechanical cell competition Cell competition is a tissue surveillance mechanism for eliminating unwanted cells and as such is indispensable in development, infection and tumorigenesis. Although different biochemical mechanisms a...

Thrilled to share our new manuscript on how force transmission can regulate mechanical cell competition!
