Go check out my thread about cell extrusion 🌸 at @epimechfc.bsky.social and give them a follow for more content on epithelia-related research ✨🧫

Hello epithelia enthusiasts! I’m @inesfournon.bsky.social and I study epithelial mechanics in sea anemones 🪼 Did you know epithelial cell extrusion had never been described outside bilaterian animals before? Well… not anymore 👀 Read ⬇️🧵1/9

Another #notTHECover unfortunately. But this gorgeous, Tron-like vibe, drawn by the amazing @munafomarzia.bsky.social for our recent #ExM work with @gautamdey.bsky.social & @centriolelab.bsky.social will still be printed out in the lab. Read here: www.cell.com/cell/fulltex...

Thrilled to share the preprint from my PhD! 🥳 Where I characterised epithelial cell extrusion in a sea anemone 🔗 www.biorxiv.org/content/10.6... Big thanks to my supervisor @prhsteinmetz.bsky.social and coauthors @noahbruderer.bsky.social @lionlchristiaen.bsky.social at🇳🇴 @msarscentre.bsky.social ⬇️🧵

How do animals with lifelong growth modulate cell #proliferation? @eudaldpascual.bsky.social @ktgarschall.bsky.social @prhsteinmetz.bsky.social show that starvation induces G1/G0 #CellCycle arrest in Vasa2+/Piwi1+ #SeaAnemone cells; cycle re-entry is TOR-dependent @plosbiology.org 🧪 plos.io/48J2o6P

Congratulations to @inesfournon.bsky.social and @ruthstyfhals.bsky.social on their amazing talks at the very first BIO-Early Career Community Conference at @unibergen.bsky.social ✨ We are proud to support this fantastic initiative that brought our local community of young scientists together 👏

Congrats to all authors! 🎉 Very happy to see this paper out where I had the chance to finish off a small part on this crazy story on what happens if you kill all the neurons and then chop off the head of a sea anemone 🪸👾

Our paper on the role of neurons in Nematostella head regeneration is now out at @currentbiology.bsky.social Big thank you to all collaborators, it was a pleasure! Ectopic head regeneration after nervous system ablation in a sea anemone: Current Biology www.cell.com/current-biol...

🚨Our collaboration with @centriolelab.bsky.social & @gautamdey.bsky.social is out today in @cp-cell.bsky.social We show that #Expansion #Microscopy is a broad-spectrum modality for Euks, enabling 3D phenotypic maps rooted to phylogeny. #ProtistsOnSky #SciComm #SciSky www.cell.com/cell/fulltex...

Exciting day for the lab: our 1rst paper is officially out in @currentbiology.bsky.social 🥳 Wonderful collaboration wt @gautamdey.bsky.social showing how Cryo-ExM achieves consistent immunostaining in diverse diatoms, from the lab and the natural environment 1/n #ProtistsOnSky tinyurl.com/2zxaund7

First neurons didn’t appear overnight. We trace their roots to ancient secretory cells - showing how lifestyle & behavior shaped the evolution of first synapses.🧠🌊 #Evolution #Neuroscience Our latest in @natrevneuro.nature.com Link: rdcu.be/eMX3E @jeffcolgren.bsky.social @msarscentre.bsky.social

What are these? You are looking at embryos of a sea squirt. Each of the 'soap bubbles' is a living cell, about a fourtieth of a millimetre in size. The outlines of the cells are visible thanks to fluorescent markers identified by Hitoyoshi Yasuo @hitoyas.bsky.social see doi.org/10.1101/2024... 🧵

Still can’t quite believe it 💫 I’ve received the L’Oréal-UNESCO For Women in Science “Jeunes Talents” France 2025 award! I’m so deeply honored — this recognition means so much to me, both as a scientist and as a woman who loves research. 💙🔬 1/3

Happy Ctenophore Day! These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈 Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab #CtenophoreDay #CombJelly #Ctenophore

Sad news: Jane Goodall has died. She did more than any other human for our understanding and appreciation of our closest relatives, the chimpanzees. That chimpanzees are Endangered tells you everything about our species and about what made her so exceptional. www.nytimes.com/2025/10/01/o...

Fantastic presentation by @malinkjosavik.bsky.social at the Tutzing basal metazoan workshop 👏 She shared her work on starvation and metabolism in Nematostella, conducted in collaboration between the @prhsteinmetz.bsky.social lab and the Dept of Biomedicine @unibergen.bsky.social ✨

Happy to share the Biodiversity Cell Atlas white paper, out today in @nature.com. We look at the possibilities, challenges, and potential impacts of molecularly mapping cells across the tree of life. www.nature.com/articles/s41...

Huge congratulations to postdoc Guillaume Poncelet @guillaumeponcelet.bsky.social who was awarded a UiB Early Idea innovation grant 🤩🎉 Inspired by his work in the @lionlchristiaen.bsky.social lab, he will be developing a new product derived from naturally occurring compounds 🔬 Read more below ⤵️

HAK-actin™ was developed in the labs of @centriolelab.bsky.social and @dudinlab.bsky.social. Find out more about HAK-actin™ in the BioRxiv manuscript: doi.org/10.1101/2025... We are grateful to @dudinlab.bsky.social for providing the creolimax frangantissima data used in the movie

New short paper from our lab @currentbiology.bsky.social, in which we discover of a new mode of cell motility for choanoflagellates: flagellar gliding. www.cell.com/current-biol... - A 🧵

Our lab is 2.5 years into #ERC funding✨ Grateful for the support that enabled us to uncover the syncytial nerve net in a ctenophore - a discovery reshaping our understanding of nervous system evolution. Stay tuned for more exciting discoveries to come @erc.europa.eu www.youtube.com/watch?v=1DAE...

Congrats to all those getting an ~ERCStG today! Also a small reminder that the University of Galway offers a permanent academic position to ERC StG holders so if anyone in the area of Chromosome Biology (broadly defined) is still looking for a home then please reach out!

Final year PhD students, I know you’re desperately trying to finish experiments/revisions/submissions/write a thesis & just survive - but please spare a few minutes to apply to your dream postdoc labs. It easily takes A YEAR from first contact, even if everything goes to plan on both sides.

I am still very much processing this!🤩 Feeling extremely happy and grateful to have finished my PhD at the @msarscentre.bsky.social 💜 Thank you to everyone who was part of this 4 year journey!

Look at those #DIATOMS LOOK AT THESE #Microtubules Congrats to the team Long-live #UExM #Expansion #Microscopy

90% of you probably don’t need to read this. But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy. It’s about sharing something hard to say out loud; partly to heal, partly in case someone needs to hear it too. (1/3) tinyurl.com/DudinO

It’s a wrap for #Pint25 in Bergen! 🥹🧡🍻 Huge thanks to our speakers, audience, sponsors & the amazing team who made this festival such a blast. Three nights of science, stories & good vibes — see you next time! 💫🇳🇴 @pintsworld.bsky.social
