Happy (and spooky) #FluorescenceFriday Switching from frogs (which are underrated btw) to zebrafish has really made me appreciate transparent tissues! 🐟 28 hpf, ⚪ nuclei, 🔴 F-actin

📣Our project, “Mechanometabolic Control of Vertebrate Limb Elongation,” has been funded by Wellcome! Over the next 8 years, we’ll collaborate with @manningresearch.bsky.social and Nathalie Agar’s group to understand the mechanics of ECM-rich mesenchymal tissues! Funded positions available!🎉

1/12 A very special moment for me! 🎉 My first paper as corresponding author—a @jcb.org Perspective on how contact-based decision-making in collective cell migration can itself encode blueprints for complex patterns and shapes. rupress.org/jcb/article/... #cellbio #devbio #science 🧵for details

Pretty cool

Our new paper is out in Dev Biol! 🎉 🐸🧬 We show #miR-196a directs #neural crest fate in #Xenopus by repressing immature neural #ectoderm — evidence #miRNAs can potentially drive, not just fine-tune, early patterning 👉 Read more here: doi.org/10.1016/j.yd... @devbiol.bsky.social @biouea.bsky.social

Thank you for sharing! I'd like to highlight the concept of embryonic 'actuation' where a mechanical state change is caused by cells acting on each other through mechanics and/or biochemical signals but importantly not mediated by fate transitions.

Got stunning fluorescence microscopy images? 🌈🔬 SDB wants to feature YOUR work for #FluorescenceFriday! We highlight images from SDB members with a short description and the image creators 📸. Fill out the form to be featured: docs.google.com/forms/d/e/1F...

I'm going to be advertising for a few positions in my group in the next couple of months for a big project on synthetic microbial communities. I would love to hear from you if you are interested and I'd also appreciate if everyone could share this far and wide!

Interesting review about the role of ECM in development!

We are searching for an enthusiastic scientist to join our team and establish annual killifish as a model system for early developmental biology and biophysics! @embl.org @embldbunit.bsky.social Apply here: embl.wd103.myworkdayjobs.com/EMBL/job/Hei... Please re-post 🙏

Thrilled to bits to see our latest work online in Dev Cell! 🥳 We wanted to know how cells build functional organs with precision🫀🫁📏 Here we show how coupling of cell shape and organ function fine tunes the form and contractile power of the developing #zebrafish heart 1/n tinyurl.com/cell-stretch

Very happy that the first article from my postdoc work in the Tomancak lab is now published @PNAS! www.pnas.org/doi/10.1073/.... We studied the self-organization of actin in aggregates made from Hydra cells. Thread below (1/9)

I was looking through my old microscopy videos, and found this perfect shot of a macropinosome forming through the collapse of an actin-driven membrane ruffle (cyan). Immediately, CRYI-A (orange) is recruited to the vesicle to finish the job. Still in awe with this process after all those years!

🪼 How did the animal body plan evolve? This ‘fundamental’ study in Clytia sheds light on how Wnt3 coordinates both gene expression and planar cell polarity during axis formation, offering key insights into the origins of morphogenesis. buff.ly/e1Un958 #DevBio

🔊 We are recruiting a postdoc to join us @crick.ac.uk and @ucl.ac.uk @ucl-ipls.bsky.social. Repost and help us spread the word and reach out if interested and have questions. Details and how to apply: www.ucl.ac.uk/work-at-ucl/...

BSDB Bridging mechanics and genetics in early development at University of Warwick was great fun and I am grateful for the opportunity to present my PhD work.

#Argonautes2025 - argonautes.img.cas.cz Join us in Prague 27-30/8/2025 for the next edition of the Argonaute meeting #miRNA #siRNA #piRNA & #PIWI Abstract submission for talk selection deadline is 30/6! Please, spread the word @rnasociety.bsky.social @rti-umasschan.bsky.social

📣 New paper out! How do thousands of cells shape the emergent geometry of the avian embryo? We identify distinct, independently controllable mechanisms that contribute to embryo size and shape. @alex-plum.bsky.social @bensteventon.bsky.social @Guillermo Serrano Najera www.nature.com/articles/s41...

1) Branching morphogenesis is fundamental to animal development, shaping complex organs like lungs, kidneys, and vascular networks. Gills are another highly branched organ. Yet, the developmental processes behind gill formation in zebrafish remain poorly understood. #zebrafish #gills #microscopy

Hooray. Yesterday, my very first #Hydra paper was accepted! An exciting time for a career #Drosophilist. Big congratulations to @anaisbailles.bsky.social, who set up the Hydra system from scratch. Thanks Carl Modes for the liquid crystal theory. @mpi-cbg.de Preprint: www.biorxiv.org/content/10.1...

Welcome to YEN 2025. We are kicking off today with Peter Rugg-Gunn who presented their impressive in vitro system of implantation and post-implantation developmentm

We heard from Yuri Takashi from @geneticscam.bsky.social showing ex vivo induction of EMT and BMP signalling in chick embryo explants.

@martanska.bsky.social from @pdncambridge.bsky.social presenting her work with gastruloids on how mechanical properties of individual cells can affect tissue level properties and morphology.

Laure de Chancel from @institutcurie.bsky.social all the way from Paris talking about chromatin mechanics and how it changes during zygotic genome activation.

Starting the short talk session we have Jake Cornwall Scoones from the @CrickLab on using NeMECiS to explore and engineer synthetic CREs to modulate gene regulatory behaviour. Check out their pre-print and workshop!

This #FluorescenceFriday feels like fluorescence xmas! Thanks for all your submissions to the YEN Image Competition. Excited to see so many spectacular visualisations of embryonic development and stem cell biology! #YEN2025

REMINDER: Last chance to submit a scientific picture or art of a embryos, stem cells or organoids to the YEN Image Competition. Deadline is 1st May! #YEN2025

Reminder that the YEN Image Competition closes next week on the 1st May! It's a great opportunity for students and postdocs to promote their research. Send us your images by email (details below)

Happy #MicroscopyMonday! I was optimising some stainings a couple years ago (this one is Stage 32 with sodium borohydride to reduce autofluorescence). Any #Xenopus people know what the rosette-looking clusters around the eye are doing? By the way, check out YEN Image Competition #YEN2025 ;)

Great opportunity to highlight your research and celebrate the great imaging possibilities in dev bio! #YEN2025

What to look forward to at #YEN2025? Well we asked you about your field and these were the 100 most common words.
