Really excited to share our new paper in @nature.com! We uncovered how a physical instability of the cytoplasm coupled with the cell cycle drives cytoplasmic partitioning in early embryos #zebrafish #drosophila. Read more in this🧵 www.nature.com/articles/s41... 🤩

Is it the "against the stream-cell" that is moving, or the other ones?

New preprint! 🚨 We uncover a slow adaptation to stretch that links star-bundling of keratin filaments with nuclear escape from its keratin cage. Led by @tomgolde.bsky.social 🙌

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

New preprint out! We show how cellular nematic order can be harnessed to program tissue-wide force fields and guide 3D shape transformations.

3 years of hard work, a fantastic team — and I’m proud to be first and co-corresponding author!
It's about Plexin signaling driving collective cell migration & organ sculpting. Check out the videos 😀

What do we see when looking at cells under the microscope? 👉Some are bigger than others, some are elongated and align with the neighbors & others seem to move. Cool, right? But wouldn't it be cooler to quantify these observations?
I'm @juliaeckert.bsky.social. Let's explore some analysis software!

Happy #FluorescenceFriday!
The tip of the cantilever consists of a fluorescent bead that contacts the epiblast. Because we know the force necessary to bend the cantilever, we can perform mechanical assays by driving the bead across the embryo and measure in real time the force applied to the tissue.
🚨📣 New preprint alert!
Excited to share my new postdoc work on direct force and mechanical properties measurements in live embryos!
A great team effort with A. Chamolly (theory), under the supervision of F. Corson and @jeromegros.bsky.social

Collective cell migration is fascinating!
Some tissues behave like fluids (motile), others like solids (jammed).
Check out some papers exploring this topic in this thread.
"Exactly! Epithelia aren't just one thing. They can behave as fluids or solids and exhibit either nematic or polar order. Thank you @epimechfc.bsky.social for highlighting this!"
Trichoplax adhaerens is one of the simplest and most enigmatic animals on earth. Its body shows incredible fluidity, changing shape within minutes. In a recent visit by Andrea Pasini we had the chance to host and observe these amazing animals live.

New in Nature Physics! In a great collaboration with @junlab.bsky.social and my students Henrik Weyer & @lwuerthner.bsky.social, we show how Min proteins in E. coli self-organize into robust, efficient patterns ensuring accurate cell division across conditions.

This movie was taken by Shinya Inuoe, who built the polarizing microscope that allowed scientists to see mitotic spindle fibers live for the first time.
Dr. Inuoe premiered his research at MBL.
How can organs regenerate fast? Bioelectricity helps -- by coupling sub-second electrical injury signals to regenerative proliferation.
First preprint from my potsdoc :D with @liujinghui.bsky.social @ritamateus.bsky.social @mpi-cbg.de and collaborators @mpipks.bsky.social @csbdresden.bsky.social
This paper was inspired by Amélie Chardac's studies on flocking colloidal particles:

Congratulations to Zihui, Sano-san, and the team on this interesting work! They found that +1 topological defects attract neural progenitors—an observation that seems at odds with expectations for an extensile active nematic. www.nature.com/articles/s41...
