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...

We probably shouldn’t have favourites amongst projects in the lab, but this one was mine. I’m so pleased we can finally share it:

I’m sorry, but it is disgraceful to be an academic who uses this technology to conduct research. It should be prohibited in all of our scholarly institutions, including universities and journals.

🎉 Our deconstructed, stem-cell–based approach to studying signaling centers and limb-development cell types is out! 🥳 So nice to see it in its final form after the preprint— and huge thanks to the community for all the enthusiasm and interest since then!
