I am delighted to announce that I will be starting as an Assistant Professor at the University of Arizona in Spring 2026. Our lab will study intestinal best4+ cells in zebrafish. We are seeking a lab manager with previous zebrafish experience – come build with us. surlab-gastro.my.canva.site

Ok, friends! If you’re a Daniocell user, it’s now available again outside of the NIH. Very sorry for any inconvenience this posed for any of you and thanks for your patience. We’re taking additional steps to hopefully prevent similar outages in the future. Happy surfing 🎣

Transitions in development – an interview with Jeffrey Farrell @jeffreyafarrell.bsky.social talks about becoming a group leader, his insights on advocacy for developmental biology and his belief in unifying single-cell biology with classical approaches. journals.biologists.com/dev/article/...

For more customized analysis using our zebrafish timecourse dataset available in Daniocell, check out this amazing resource DaniocellDesktop. Extremely happy to see this brainchild of @jeffreyafarrell.bsky.social out in the wild.

Spiralia enthusiasts!! 🐚🐙🐌💛 Our amazing speaker for the Spiralia Satellite symposia at the #PASEDB2025 Néva Meyer, Associate Professor, Clark University Organizers: Christina Zakas and @albertinlab.bsky.social #evodevo #pasedb #spiralia

It was so awesome to have @jeffreyafarrell.bsky.social here to give a departmental seminar today!!

With a published genome & advancements in gene editing, the field of #zebrafish genetics has exploded in recent decades. We take a look back at major achievements in this infographic. For more, read this book chapter by @varshneylab.social et al (2015)($) doi.org/10.1016/bs.a... #ZebrafishFunFacts 🧪

Masters of regeneration? #Zebrafish are capable of regenerating their fins, spinal cord, pancreas, skin, retina, heart, liver, brain, tendons, hair cells, & kidney. For more info on this amazing species, read this primer on regeneration: journals.biologists.com/dev/article/... #ZebrafishFunFacts 🧪

I thought this was an interesting interaction! This Polychaete larva (possibly Spionidae?) has somehow got inside the tube of a Lanice sp. (sand mason worm) larva! The tube resident doesn’t seem too fussed about the visitor though. 🦑 #plankton

Happy to share a new preprint from my lab! We characterize the on/off kinetics, light dosage-dependence, and more for a suite of optogenetic signaling activators in zebrafish embryos 💡 www.biorxiv.org/content/10.1...

“These findings support the use of zebrafish as a useful comparative model for studying the meninges, provide a foundational description for future zebrafish meningeal research” New work from @biomarina-vg.bsky.social & Weinstein Lab at NIH 🐟

Great new work led by @biomarina-vg.bsky.social on zebrafish meninges! Particularly 🤩 is the descriptions of ependymin-expressing meningeal cells (not a fibroblast!) & ablation studies showing their essential role in viability. So much more to learn! Congrats Marina & team on this great work! 🦓🐟🧠

🫀 Zebrafish protein unlocks dormant genes for mammalian heart repair. Our work published by @springer1842.bsky.social in Nature CVR uncovers how the protein HMGA1 could unlock mammalian heart repair. rdcu.be/d5owa #HeartHealth #Regeneration #Biomedicine #Cardiology

Closing out the year, @cbellegarda.bsky.social and @franziau.bsky.social argue that zebrafish have much to teach us about diversity. Well, diversity among motor neurons that move the eyes, anyway 👀. Plus read our opinionated takes on current articles too! authors.elsevier.com/a/1kL%7Eb3Q9...

Signal timing determines transfating outcomes Read this Research Highlight showcasing work from Alejandro Berrio, David McClay @duke-university.bsky.social and colleagues: journals.biologists.com/dev/article/...

Out now in Dev Cell! scRNAseq trajectories describe the cascade of gene expression as cells differentiate, but turning them into a clear understanding of the underlying biology of a cell type's development remains challenging. authors.elsevier.com/c/1k9qj5Sx5g... (1/)
