Super cool work! I feel that cilia disassembly needs more work like this one. Congrats!! 🎉

5 and 7 here :)

The A–C linker structure!!! 🤩 Beautiful work. Even if you’re not as centriole-obsessed as we are, you’ll appreciate the elegance and complexity. Amazing to see U-ExM proteins in human centrioles fitting right into these densities. Congrats to all!

Schematic overview on how MicroSpit operates. It can split superimposed structures in fluorescent image channels by using a suitably trained AI.

Concrete example for how MicroSplit unmixes four superimposed structures.

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards…
What would you do with this?

Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵

#BlueSoup So nice! Hahahha
Please tag me when u know, I'm curious🧐

I found these immune cells just finished mitosis but their midbody is still yet to be resolved. How cool? If you zoom in to the midbody, you can see its classical shape just like in the textbooks. I love these little details.

Stoked to share TWO preprints on mitochondrial pearling! 🎉
We uncover how spontaneous #mitochondria pearling drives #mtDNA nucleoid distribution (doi.org/10.1101/2024...), and
@gavsturm.bsky.social
et al. dissect the biophysics behind it (doi.org/10.1101/2024...). Details below! 🔬🧵🧪


1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.

Heading to HD! Despite my sleepy face I can promise that Im very excited to join the Seeing is Believing 2025 @events.embl.org If you are interested in centrosomes, centrioles, expansion microscopy or protist, don't be shy and let's have a chat! ☺️🤗 #EMBLSymposium #microscopy

Love this one, specially the 2 routes of primary ciliogenesis😍😍

Now out on bioRxiv. 🥳My research on #cytokinesis, averaging thousands of #ExM images🔬, creating a dynamic atlas of cytokinesis 🦠⏳. Here's an animated sneak peek of what we found. Better resolution on bioRxiv😄 #PSFoftheGIF

Super cool! Congrats!

#GEF25 the expansion microscopy community would benefit from high NA, long working distance water objectives. Who's working on these? What's out there?

Be our new colleague! 🎉
The Dept of Molecular and Cellular Biology at the University of Geneva is hiring an Assistant Professor or Associate Professor.

Finally 🥂

Our latest preprint on the role of the Arp2/3 complex in mitotic entry is now available @biorxiv. This work was done by Dhanya Kalathil, a very talented postdoc in my lab. The story started in 2019 when we were investigating the role of branched actin in cytokinesis. 1/

Lately I've been only posting images of really interesting protist here, but something that many don't know is that most of my time i'm expanding 'boring' mammalian cells and that I love human centrioles. Don't tell me that they are not beautiful😍👁️

It’s truly inspiring to see how persistence, collaboration, and communication across disciplines can transform ambitious ideas into such impactful stories. Seven years, four interdisciplinary teams, and countless discussions later—this really shows the power of timing, teamwork, and shared vision!😍

Cells can form patterns within themselves just like embryos do. How? Connie Yan's new preprint shows how the anterior-posterior cytoskeleton pattern in Stentor is dictated by regionalized scaffolding proteins

📢 Excited to share our new study in Nature Communications!
We show that the A-C linker safeguards centriole architecture & controls duplication. A big congratulations to Lorène for this beautiful discovery, which represents 4 years of her thesis work.

Thrilled to share our newly published work in @natcellbio.nature.com.
We found that differentiating cells tune the size and architecture of mitotic organelles through changes in cytoplasmic density.
Many thanks to my fantastic co-authors! 💥
