“Importantly, we find that reduction in germ cell motility is correlated with the decay of RNA encoding for Dead end 1 (Dnd1), a conserved vertebrate RNA-binding protein that is essential for PGC migration.”

New work from @erezraz.bsky.social et al featuring #zebrafish primordial germ cells 🐟

Super congrats to Prof. Lisa Manning @syracuseu.bsky.social! #zebrafish

What legends! Additional congrats to Profs. David Grunwald @utah.edu & Ela Knapik @vanderbilt.edu! #zebrafish

Advancing knock-in approaches for robust genome editing in zebrafish Summary: This paper describes a robust toolkit for efficient and precise genome engineering in zebrafish, with broad applicability to other model systems.

A powerful new toolkit for precise genome engineering in #zebrafish.

This study from the group of Junsu Kang introduces a versatile mini golden system which allows for one-step customization of donor templates + a synthetic exon strategy enabling highly precise genome edits.

AFOG staining of an adult female zebrafish that is egg-bound. You can see the cloaca on the left with lots of collagen (blue) and villi(?). On the right, you can spot oocytes at various stages of maturation. Captured on an Evident Slide Scanner.

The #zebrafish cloaca is bizarre and beautiful, as spotted looking for something else! Here it is in an adult female stained for collagen (in blue). I should probably mark this as sensitive content, right? 🤦 #FishNotPeople

Finished your PhD & looking for a Postdoc position? Intrigued by #zebrafish heart morphogenesis? Job available in the @rashmi-priya.bsky.social Lab at @crick.ac.uk (Initial 4 years funding w/ potential for 2 additional years)🐟❤️ More details: crick.wd3.myworkdayjobs.com/External/job... Please share 🧪

The Gölz Lab investigates how environmental chemicals—including per- and polyfluoroalkyl substances (PFAS)—perturb intracellular signaling networks and how these early molecular events propagate across biological scales to drive functional tissue changes and organismal phenotypes. Guided by a One Health perspective, we connect environmental exposure to mechanistic pathways relevant for human and ecosystem health. We integrate human iPSC-derived 2D systems, such as advanced 3D organoid models, and zebrafish embryo assays to dissect conserved pathways and derive mechanistic, dose-resolved effect chains.

Want to live in a quaint German town & work w/ #zebrafish toxicology models? Openings in Gölz Lab in Heidelberg!

Our superhero Neta Hart volunteered to come in to the lab and take care of our fish, no matter what, even under missile attacks.

We gave her this not-even-nearly- appropriate diploma 💪🏼🐟

#regenerativemedicine #zebrafish #heart

7 day old zebrafish embryo with green-glowing cells outlining the cardiovascular system, craniofacial muscles (faint), and the heart, with undulating blood vessels around the developing gut and glowing pectoral fins. Embryos has been imaged from below, with head facing up.

“Crucially, we demonstrated that [thyroid hormone] acts upstream of the Notch pathway to regulate growth of the [non-skeletal peripheral edge of caudal fin].”

Hi all! 👋
Looking for a plasmid with the gnrh3 promoter driving a FP (GFP or similar) 🐟
The construct itself — not a transgenic fish line.
Does anyone have it or know a lab that does? 🙏

Foundational work in #zebrafish can be credited to "fruitful" discussions between #Drosophila researchers such as José Campos-Ortega & Christiane Nüsslein-Volhard. By the late 1980s, multidisciplinary approaches honed in flies were finally applied to a vertebrate. #ZebrafishFunFacts 🧪

I’m particular interested in recruiting people from the Americas or East Asia & Australia/New Zealand. If you have a love of fish and find joy in #scicomm & public outreach, this could be a good fit for you 🙏 #zebrafish
