See this? This = implanting mouse embryo. Usually this happens inside its mother and is invisible to us, but we can actually watch implantation ex vivo with the hope of understanding why implantation goes awry in embryos of older women. A 🧵...

We present a simple method to easily increase the imageable depth of an expansion microscopy gel on a typical inverted microscope ten-fold, using some carefully placed FEP film and a water dipping objective lens:

A comparison of imaging an expansion microscopy hydrogel with a water dipping objective lens, using either eye gel as an immersion medium or a combination of Immersol W, water and a thin FEP film. In both cases, the sample is supported by a thin FEP film rather than a coverglass.

It is out! 🦚 I recorded hundreds of #ExM 🔬images of cytokinetic bridges and averaged them into 6 stages. How? With help from our fantastic collaborators @zacsimile.bsky.social and @jonasries.bsky.social in Vienna 😇. Check out the full atlas here: doi.org/10.5281/zenodo.17232370

Sketches of six stages of cytokinetic development of the intercellular bridge are illustrated with exmaple U-ExM fluorescence microscopy images. Septin2-GFP shown in green. Tubulin shown in magenta. A shortened workflow illustrates the image alignment and averaging process to generate average 2D reconstructions of cytokinetic stages.

Another welcome distraction from the dissertation awaits right next to the office: #BioMembraneDays25 are such a great gathering, spanning membrane and lipid #biophysics to physiology. The food is outstanding too 🤗. Thanks to organizers @ewerslab.bsky.social @dimovalab.bsky.social and Thomas Weikl!

Taking a break from my thesis marathon and enjoying the lecture by @eboyden3.bsky.social at the #GEF25 😄. A wonderful ride through the beginnings, present and future of #ExM 🔬. What a great opportunity to join via live stream, big thanks to the organizers @alishaib.bsky.social and Silvio Rizzoli 😊

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
