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.

📢 Paper alert 📢

Chirality is known to be important for the movement of microorganisms and active matter. In our new paper out today in @natphys.nature.com, we show that chirality is used by malaria parasites to control their motion patterns:

Multiplexed imaging of G-proteins and ERK activity upon activation of CaSR
We have previously shown that the calcium sensing receptor (CaSR) activates different G proteins and second messengers in single cells, and that GPCR and G protein-mediated ERK activity can be highly ...

Fascinating #EpithelialMechanics thread by @jorgealmagro.bsky.social, exploring the connection between tissue geometry and tumor growth 👇
It’s time to talk about epithelial geometry and cancer. How can the architecture of an epithelium affect how tumors will grow and spread? In this thread, @jorgealmagro.bsky.social

The law of the jungle.
Interactions of cells in a collective lead to global rotation.
In 80% of the case HUVEC cells turn clockwise.
How many cells does it take for this to happen?

The lab’s first pre-print! We investigated how growth-inducing Erk activity waves are regulated in regenerating zebrafish scales. We discovered that Erk waves are followed by waves of expression of their own inhibitors, as predicted by excitable waves theory. tinyurl.com/26r2cmpj

Hi, I’m David Brückner @davidbrueckner.bsky.social.

I’ll take you through how cells in a tissue can use information distributed by biochemical gradients to make decisions, and how we can measure such positional information.
