Biophysics of lumen morphogenesis Read this Review from our special issue #DevSIextracellular by Byung Ho Lee, @hiraiwatetsuya.bsky.social, Masaki Sano, Alf Honigmann, Daniel Riveline, @anne-grapin.bsky.social and colleagues. doi.org/10.1242/dev....

My first paper is officially out in @currentbiology.bsky.social ! We found that snake embryos coil due to a mismatch in growth rates between the gut and spine. This tight coil is one of the reasons why snakes are able to get so long. Read the paper here!

A developmental biologist's guide to mechanics, just out in Development! In which we learn about the three pillars of any mechanical model: forces, mechanical properties, and boundary conditions. @pflenne.bsky.social @alessandrochppr.bsky.social @caojialing1002.bsky.social @dev-journal.bsky.social

I'm excited to see @dev-journal.bsky.social's #DevSIextracellular take shape with articles like this one. The special issue will be completed soon. A big thanks to @hugheslabpenn.bsky.social & @rashmi-priya.bsky.social for their contributions as Guest Editors. Browse the Table of Contents so far:

Happy #FluorescenceFriday! ✨🔬 A peek inside a developing quail embryo, where the brain and heart are already taking shape. A tiny embryo doing some seriously impressive developmental heavy lifting. 💪❤️ 📷 @vanderspuy.bsky.social

Amazing 😍

For this #FluorescenceFriday 🔬 A glimpse into our latest work: Shroom3 influences pillar cell contractility and establishes a mechanical threshold for gill lamella stability. #Zebrafish ⚪ Pillar cell nuclei 🔴 Contractile apparatus More soon — multi-post thread coming! 🧵 🔗 doi.org/10.64898/202...

Happy #FluorescenceFriday ! I have cuticula-shedding office company at the moment, so I took the opportunity to take some cool autofluorescent images of Flossis cuticula! (Plus an image of Flossi herself!)

We now have 4,426 trees for published articles and 12,662 trees for peer reviews in The Forest of Biologists. Thank you to everyone who has contributed.

Excited to share a new preprint from the lab, by @andrewmatheson.bsky.social and team, where we dive into the superpower of newts: plasticity! www.biorxiv.org/content/10.6... Like many good projects, this started with a serendipitous observation... 🧵1/5

I am excited to open my lab at @ibioillinois.bsky.social in Spring 2027! We will use zebrafish & other fishy friends to reveal the genetic basis of large scale changes in the vertebrate body plan, and how this impacts both human health and evolution. Join me at UIUC! 🧬🧫🔬 www.hawkinslaboratory.com

Happy #FluorescenceFriday! 🔥🧪🔬 A blaze of neural crest cells migrates through a developing quail embryo on one of embryonic development's most epic journeys. Beautifully captured by @vanderspuy.bsky.social 👩‍🔬🐣 #Devbio

I feel honored that my Perspective article with @mayorlab.bsky.social on collective cell migration has been featured in this special collection. Many thanks to the curators, @wumin-lab.bsky.social and Gabriele Stephan, as well as @jcb.org rupress.org/jcb/article/... #CellBio #CellMigration

Awesome group, fantastic environment! If you're interested in theoretical biophysics, send your application! #cellbio #science #physics

New paper from the lab! We show that laminin α5 and two integrin receptors (α3, α6) team up to guide a group of cells moving together inside a living embryo (doi.org/10.1242/dev....) Congrats Anna & Nicola. Thanks to @chaitanyadingare.bsky.social and all authors, and to @dev-journal.bsky.social.

Even more zebrafish😍 #EZM2026

Already spotted some #zebrafish in Vienna #EZM2026

Our team is already gathering in Vienna at the #EZM2026. Looking forward to meeting you all! 🐟🐟🐟

Happy #FluorescenceFriday! Eye of a zebrafish embryo🐟

We're very excited to announce the official launch of the Journal of Regeneration. Together with the amazing team from @pensoft.net and my two co-EICs Loriano Ballarin and Buki Rinkevich, it is such a pleasure to share this new platform for bringing together the regeneration biology community.

New research finds that the ovaries of old mice become infiltrated with immune cells and may secrete immune signals into the body. The consequences of these changes aren’t clear, but a similar transformation in humans could have health implications after menopause. https://scim.ag/4oJAGOK

1/ 🧬🔬 How does one cell become an entire animal? We can now film it in 3D 🐟, but turning those movies into accurate cell tracks is brutally hard. Enter our new #Kaggle challenge: $60K prize pool, to help crack 3D+time cell tracking at scale! 🧵👇 www.kaggle.com/competitions... @biohub.org

Excited to share the final published version of our work on the evolution of dorsal-ventral patterning in fins and limbs, now up on @currentbiology.bsky.social In review we added new single LARM element deletions to assess their impact on dorsality. Take a look! 🔬🧪🐟🐁 www.cell.com/current-biol...

Read about how research into lymphatic function is changing our understanding of immune regulation in the lungs in our review: doi.org/10.1016/j.co... Congratulations to co-authors Amy Rivers and Camila Migues Ramirez!

The array of organs in the animal body differ dramatically in their architecture, but cell-cell adhesion mediated by cadherins is a common principle. Our lab usually focuses on epithelia but cadherins are also active in migrating mesenchymal cells like these migrating testis myoblasts 1/n 🧪

As Editor of @dev-journal.bsky.social I get asked "What are you doing about your impact factor?" In our new editorial we say: Ask not what Dev can do for the impact factor. Ask what you can do for Dev's IF The IF is about how we all cite, review & assess each other's work doi.org/10.1242/dev....

New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

Very excited to be sharing our new paper, just out in Nature Cell Biology! The big question we investigate: How do migrating cells put their front 🔴 and back 🔵 in the right place?
