Yaaay! Great to have you back!

If you’re interested in joining our new lab at @uarizona.bsky.social as a #labmanager, please send a CV and brief cover letter to surabhinav@arizona.edu. Experience with zebrafish husbandry is a must, and experience in molecular biology or microscopy is a plus. You get to set the rules!

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.

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.

I’m doing fine, hope to catch up with you next week at IZFC

Big congratulations Kristen!!! This is such wonderful news.

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.

Jeff Farrell about to start his seminar

5 people at dinner

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

Timeline of important technological developments in zebrafish research.

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 🧪

Organ regeneration in the zebrafish. Summary of some of the organs and tissues used for regeneration studies in zebrafish. Preferred injury models are annotated for each organ. Image and text credit to Marques et al. (2019) https://doi.org/10.1242/dev.167692

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

Many congratulations Miranda!

Congratulations!!

An optogenetic toolkit for robust activation of FGF, BMP, and Nodal signaling in zebrafish Cell signaling regulates a wide range of biological processes including development, homeostasis, and disease. Accessible technologies to precisely manipulate signaling have important applications in ...

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.

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...

Figure 5 (A) Top: Mid-sagittal sections of control embryos at 14, 16 and 21 hpf. Skeletogenic cells are labeled green by the hybridization chain reaction (HCR) targeting msp-130, blastocoelar cells labeled yellow with HCR targeting astacin4, and pigment cells labeled red with HCR targeting pks1. Bottom: Micromereless embryos at the same three time points and stained with the same HCR probes.
