A super detailed protocol + video on Cryo-ExM - Cryo-Expansion Microscopy, led by the labs of our former postdocs @marinelap.bsky.social & @ebertiaux.bsky.social.
Clear, practical, and very useful for anyone doing nanoscale imaging 🚀 app.jove.com/t/68595/expa...

JOB ALERT: Operations Director (DCI–Lausanne).
The DCI, a joint initiative of EPFL, UNIL, UNIGE and UNIBE, is recruiting an Operations Director to lead the cryo-EM facility in Lausanne.

Christmas party 🎄- The lab went full senior mode (and won the best costume). You all rock 😄 !!!!!! (If you’re wondering where the youth went… check who’s been quietly draining the lab’s energy 😈)

We’re excited to announce the opening of the Geneva Expansion Microscopy Facility (GenExM)!

GenExM is a full-service U-ExM platform (U-ExM, Cryo-ExM, iU-ExM), delivering nanoscale imaging.

Led by Dr. Olivier Mercey, GenExM welcomes academic & industrial collaborations.

👉 www.unige.ch/genexm/

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

👉 More details here: lnkd.in/e8Z9eAm4
👉 Our department: mocel.unige.ch

Please feel free to share this opportunity with your network.

Trouble imaging actin in ExM? Meet HAK-Actin, a probe for U-ExM, cryo-ExM & iU-ExM. Enables post-expansion labeling for max signal. www.biorxiv.org/content/10.1...
Soon at @spirochrome.com
Led by O.Mercey and @lreymond.bsky.social, in collab with @dudinlab.bsky.social and @marinelap.bsky.social

📢 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.

🚨 New preprint!
Using U-ExM + in situ cryo-ET, we show how C2CD3 builds an in-to-out radial architecture connecting the distal centriole lumen to its appendages. Great collab with @cellarchlab.com @chgenoud.bsky.social @stearnslab.bsky.social 🙌. #TeamTomo #UExM

Mark your calendars! The CSHA Cilia & Centrosomes meeting returns this November 2025, can’t wait for what’s sure to be an exceptional gathering of the community.

New lab preprint! Unveiling the Molecular Architecture of T Cells and Immune Synapses with Cryo-Expansion Microscopy (Cryo-ExM). A fantastic collaboration with Dr. Benita Wolf. Congratulations to all authors, especially Florent Lemaitre, for leading this amazing work! www.biorxiv.org/content/10.1...

Fantastic paper! Excited to dive into the details, and great to see some U-ExM on Asgard archaea! Huge congrats to the entire team! 👏🎉"

Huge congratulations to @marinelap.bsky.social for receiving the 2025 Young Researcher Award! 🏆👏 sbcf.fr/en/newslette...

Thrilled to have collaborated with the Lansky/Braun Lab on this exciting project: Cell-free Reconstitution Reveals Synergistic Stabilization of Microtubule Doublets by PACRG and FAP20 !
