I had a lot of fun working on this collaboration and revisiting the scRNAseq data. Although I work on zebrafish now, I still haven't forgotten my spiralian roots. Thanks @chemamd.bsky.social @baxevanislab.bsky.social and Elaine Seaver for the opportunity.

Today is #RareDiseaseDay & we are celebrating by highlighting the invaluable work of the Undiagnosed Diseases Network (UDN)! Formed in 2020, it aims to solve the most challenging medical mysteries using advanced technologies. In this thread, we will highlight their use of the #zebrafish model. 1/5 🧪

Happy International Day of Women & Girls in Science! Today & everyday I am grateful for the opportunity to work alongside & learn from this talented group of women scientists. Funded by grants from the NIH, this team is working to understand how the gut microbiome affects our digestive health.

Switching fields or wanting to become an expert in #zebrafish research? The @mblscience.bsky.social 2026 Zebrafish Development & Genetics course offers a fantastic opportunity to learn from leaders in the field! Application deadline: March 2 Please spread the word! www.mbl.edu/education/ad...

A very well deserved award for a wonderful scientist and mentor. My time in Jeff’s lab has undoubtedly been one of the most enjoyable and enlightening periods in my scientific career.

Happy New Year! NEW LAB PREPRINT testing how best4+ intestinal epithelial cells develop! best4+ cells are conserved across vertebrates and altered in IBD & colorectal cancer. But they were first molecularly IDed in 2019. We barely know anything about them yet! What do they do?? HOW DO THEY GET MADE?

Closing out 2025 with our new preprint where @jeffreyafarrell.bsky.social and I explore development and function of zebrafish intestinal best4+ cells – molecularly described in 2019, conserved in evolution, absent in 🐭, and altered in inflammatory bowel disease. www.biorxiv.org/content/10.6...

Check out our recent preprint, "Live longitudinal imaging of meningeal cerebrovascular injury and its sequelae in adult zebrafish." lnkd.in/gN7z6th4

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/)
