- Cool thread with examples of the role of cell junctions in collective cell migration! 🧪
- How do cells orchestrate themselves to achieve a directional movement as a group? Hi, I’m @sayukihirano.bsky.social. In this thread, I’ll highlight key mechanisms of how cells communicate with each other to perform directional collective migration.

- #LivingArchitectures Congratulations @manuelthery.bsky.social @lblanchoin.bsky.social and all Scientists of the #CytoMorphoLab for their poetic vision of the microscopic level.
- Using micropatterning & thousands of hours on the microscope @manuelthery.bsky.social and the #CytoMorphoLab reimagined the Musée D’Orsay. Accompanied by an orchestra and poet, their images transported us into the cellular universe. I remembered why I am a cell biologist. All of this is in us. Wow!

- A few seconds of eternity: From microscope to museum❣️ It was truly delightful to be part of this project, celebrating life as a continuous dance of creation, collapse, and renewal. 🔄 Kudos to @manuelthery.bsky.social @lblanchoin.bsky.social #cytomorpholab members, and @museeorsay.bsky.social

- Happy to highlight our collaborative work from our @ijmonod.bsky.social team with @destriano.bsky.social, B. Goyeau and M. Chabanon. Cytoplasmic crowding acts as a porous medium that hinders macromolecular diffusivity. Plus: a clever way to measure cell volume. www.pnas.org/doi/10.1073/...

- This weekend we projected cells and filaments on the roof of the @museeorsay.bsky.social in Paris, then we contracted it with a pinch of myosin. And it was fabulous! Grateful to have been part of this art/science project & thx to @manuelthery.bsky.social @lblanchoin.bsky.social & the CytoMorphoLab
- Some more snapshots :-)
- And here's my small contribution, an actin dynamic state that continuosuly contracts, on the roof of the museum!

- 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.

- New preprint! We show how mesoscopic nonequilibrium fluctuations in active gels emerge from the breaking of detailed balance at the molecular scale. Warning: Long technical paper ahead! Enjoy! @mpipks.bsky.social @ub.edu @ubics.bsky.social @icreacommunity.bsky.social arxiv.org/abs/2601.20483

- 🎉Exciting findings out today in Nature @nature.com from the PoL group of Jan Brugués @brugueslab.bsky.social! The authors describe a new mechanism driving cell division during early development in #zebrafish, fundamentally altering our view of the process. Read the press release: tud.link/2s3bxj
- New collaborative preprint! A striking result: a disordered linker in KANK1 binds as many as 15 LC8 dimers, forming a protein rod that bridges cell membranes and microtubules! www.biorxiv.org/content/10.1...
