I thought #fluorescencefriday would be a good opportunity for my first post here. Here are some crazy actin dynamics imaged with TIRF

This Wednesday @bgraedel.bsky.social defended his PhD — crowning an extraordinary scientific journey. He showed how live-cell imaging and computational modeling can reveal and perturb cytoskeletal dynamics at micrometer and second-level scales. Thanks Benjamin — a wild, inspiring ride! 🚀

Excited to embark on this scientific journey with Ewa Paluch and Daniel StJohnston to understand fundamentals of epithelial tissue and cell shapes! Thank you to @erc.europa.eu for the support!

HL60 cells take on so many fun shapes as they migrate! This #InsightFromImaging data features cells prepared by Leanna and imaged on the @aicjanelia.bsky.social LLSM by @cmhobson.bsky.social

Incoming deadline - 7 November 2025 Apply for a @jcellsci.bsky.social @focalplane.bsky.social Training Grant to support your attendance at a #microscopy or #bioimageanalysis training course. Open to ECRs in #cellbio. For more info: www.biologists.com/grants/jcs-f...

Which features of tissue flows are most robust and how do they emerge from #EpithelialMechanics? I’m @alex-plum.bsky.social (@mattiaserra.bsky.social group) and I’ll be sharing some papers on characterizing and controlling avian gastrulation flows.

When #halloween meets #FluorescenceFriday 🎃

Breathtaking... These are fish gills! Reminds me of something that you'd find on a #coralreef... Sea pens?

Can't believe it — my first‑author paper is out and my image graces the cover of @dev-journal.bsky.social 🎉 Here, we reveal how early developmental programs shape and maintain #zebrafish gill architecture throughout life 🔗 journals.biologists.com/dev/issue/15... #FluorescenceFriday #LifelongDevSI

Mark your calendars! The next SFB 1348 International Meeting will take place in #Münster from May 27-29, 2026, with a focus on #Mechanochemical signals at cellular interfaces. Stay tuned for more details and updates at www.uni-muenster.de/SFB1348/en/m...

Save the date for this super exciting meeting with an outstanding lineup of speakers! I love the brand hot 🔥 header image by @maikbischoff.bsky.social @sfb1348.bsky.social @uni-muenster.de

A amazing lineup including lab alum @maikbischoff.bsky.social !!!

How can we see the cells that make up a living organism? Membrane-localising tags can drive fluorescent proteins to the cell's outer membrane, making their outlines visible. But the tags don't work well in all organisms. How do you find one for your species of interest? 🧵 Check our latest preprint

Maybe it's time we rethink the idea that development is a cell centric process? In this beautiful review, María-del-Carmen and @stramerlab.bsky.social discussed how the ECM underlies and influences many morphogenesis processes from wing unfolding to mammary gland development. doi.org/10.1016/j.cd...

New publication : Despite being a core member of the PCP pathway, Vangl2 can play roles unrelated to planar polarity. This is the case during mouse heart morphogenesis.

One out of many reasons why gills fascinate me 🔬🧬 PS: A recent study showed that the outer ear cartilage shares gene regulatory programs with the gill filaments of fishes and amphibians — the gills program has been repurposed to create parts of the human ear 👂 🔗 pubmed.ncbi.nlm.nih.gov/39788155/
