When a larval zebrafish twitches its tail, the vascular endothelium lights up with a calcium signal, mediated by Piezo1. We used to think mechanosensing in endothelial cells was about sensing blood flow, but at least in this case it's about sensing body motion.

Happy to have been part of such an amazing team of scientists! If you are curious about how stiffness regulates neuronal maturation, give this a read. #xenopus #mechanobiology

An excellent opportunity to do your PhD in a fantastic lab with an incredible mentor!

Huge congratulations!!!

Thanks,DionnHargreaves LabWoolner @dev-journal.bsky.social for highlighting our preprint! Curious how mechanical and chemical signaling guides axons or how frogs are excellent for this question? @franzelab.bsky.social @evapillai.bsky.social🐸🧠 check it out #xenopus #Devbio #mechanobiology

So excited that our latest work is out! We have been working to understand how damaged tissue exits regeneration and returns to normal gene expression, and found a major role for the pioneer transcription factor Zelda in flies. Kudos to @anishbose.bsky.social @keatonschuster.bsky.social et al!

Experimental embryology postdoc available in my lab at the @biology.ox.ac.uk @ox.ac.uk working on the evolution of vertebral counts. Reach out if you’re passionate about EvoDevo, enjoy lab work and microscopy and are into or could get into cichlid fishes. Deadline on the 16th June. Please share!

High impact, small size. We welcome papers that address findings from a single set of experiments, or that are substantial enough to stand alone in 1,500 words or fewer. Find out more 👇

“Our comprehensive atlas serves as a valuable resource to the cardiovascular and regeneration scientific communities and their ongoing efforts to understand the molecular and cellular mechanisms underlying vertebrate heart regeneration.” New work from Ying Su Lab 🇨🇳 🔗 www.nature.com/articles/s41...

“Together, our results establish this optogenetic toolkit as a potent experimental platform to rapidly, directly, and adjustably activate FGF, BMP, and Nodal signaling in zebrafish embryos.” New work from @leanneiannucci.bsky.social & @katwrog.bsky.social 🔥

Are material phase transitions more than simple regulators of tissue deformability? Check our latest work uncovering that rigidity transitions can trigger cell polarity! Congratulations to @laura-rustarazo.bsky.social , @crisp-c.bsky.social and Adrián for leading this work!

Recent work from our lab: Niepukolie Nipu shows that methylene blue, at recommended concentrations used in embryo medium, affects metabolism and behaviour in larvae. These findings point to an overlooked confound relevant to larval zebrafish use in (eco)toxicity testing and the zebrafish community.
