Happy #FluorescenceFriday! Eye of a zebrafish embryo🐟

🌟 Meet the #SDB2026 Social Media Workforce!🔬 Matyas Bubna-Litic @matyasbl.bsky.social is a Postdoc in Mongera lab at University College London (see a 🔬? it’s probably him 😉). He studies how mechanics and signaling interact during tissue elongation using synthetic embryo models 🧫

Check out the YEN Image Competition. The spectacular image on the YEN 2026 poster was the winner of last year's competition!

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

Mouse (Mus musculus) 🐭 is the powerhouse of mammalian genetics, essential for studying embryogenesis, organ development and gene function using transgenic technologies. 📸 Image by Zhong Hua also featured on the cover of Developmental Biology textbook (11th edition) #ModelMonday

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.

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!

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.
