A sneak peak of a complex and technically challenging experiment that my lab developed: doi.org/10.1096/fj.2.... Super proud of PhD candidate Hannah Johnson for showcasing our Whole-gut spatial genomic analysis in #zebrafish. This video illustrates one landmark in the protocol after multiple 1/3
This developing quail embryo looks like it's thinking fiery thoughts for #FluorescenceFriday 🐣🔥🧪. Imaged by the fantastic @vanderspuy.bsky.social

Latest work from the lab by Aude Nommick et al., in which we propose a "size-scaling" model for microtubule force exertion that regulates centrosome centration vs decentration during embryo development!

A protein called Uninflatable acts as a switch between glial cells growing and glial cells wrapping themselves around axons.

Excited to share Alison's @alisonkickuth.bsky.social paper from the lab out in @nature.com this week! We uncovered how a mechanical ratchet mechanism drives cytokinesis in early #zebrafish embryos. Read more in this thread 🧵 and at www.nature.com/articles/s41... 🤩

New paper out!
We show how mechanosensitive adherens junction proteins link actomyosin contractility to actin assembly using in vitro reconstitution.
Huge congrats to Aurélie Favarin, Rayan Said, & all authors!

I don't always get pretty, isolated, AND transfected primary neurons in culture, but when I do I take advantage.... Rat hippocampal neuron overexpressing ThymosinB4-mScarlet and imaged for 16hr on a @zeiss-microscopy.bsky.social LSM880 with Airyscan. #FluorescenceFriday #Microscopy
Confocal microscopy image of a juvenile sea star (Patiria miniata) viewed from the oral side. The animal has a five-armed, star-shaped body with a central nerve ring. The nervous system is labeled in green, forming radial nerve cords extending into each arm, and cell nuclei are labeled in red throughout the animal. The image appears against a black background and has a holiday-ornament-like appearance.
Felt a little festive at the microscope this morning for #FluorescenceFriday 🎄
Here’s the nervous system of a juvenile sea star ⭐️
Green = acetylated tubulin, red = nuclei
Happy holidays!
✨ Blinking #nanobodies that work for single-molecule localization 🔬
Our new preprint shows that the self-blinking dye JF635b restores robust, buffer-free blinking in #nanobodies, enabling reliable #dSTORM, #MINFLUX, and more, without chemical-switching buffers. Opening new possibilities for #ExM!

I am presenting at the Science and Art Minisymposium at #CellBio2025 today! The line up is great this year. I am hands down the least qualified person presenting. It is a weird feeling but I am excited! Here is my title slide.

since you made it all the way to then end - we've already made transgenic lines with the mSG from Ando et al - it's amazing! here's a movie from our Cell Observatory project at the Advanced BioImaging Center 7/7
Our Science paper is out!
Huge congratulations to @huabin-zhou.bsky.social, Mike Rosen, and the brilliant @janhuemar.bsky.social @juliamaristany.bsky.social and @kieran-russell.bsky.social from our group

New preprint! Do you like ocean waves? We found similar waves on bacterial colonies! We found that this collective behavior, known as rippling, is nothing but surface waves on an active nematic. @princeton.edu @mpipks.bsky.social @ub.edu @icreacommunity.bsky.social

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
