This is two stories in one: a case study/cautionary tale on developing genetic tools in new organisms, and the first hint at a gene regulatory network for choanoflagellate multicellular development (which turn out to involve a Hippo/YAP/ECM loop!) A 🧵

Finally, the excellent postdoc work of Emmanuel Haillot is out, where he dissected the integration of Wnt, MAPK and Notch signaling in defining mesoderm and endoderm identities in the diploblast Nematostella. Strikingly similar to sea urchins. www.nature.com/articles/s41...

Latest paper elifesciences.org/articles/107... closes an important cycle in our efforts to study regeneration: week-long recordings allow us to observe the behaviour of cells during the entire course of regeneration in a crustacean leg – bright objects in movie are fluorescent nuclei of cells. 1/6

Ctenophores possess a unique aboral organ that acts as a multisensory center, controlling complex behaviors. We’ve now created a ctenophore model integrated with our 3D volume EM data. Puts it into perspective.

our unexpected results on the importance of a neural cell adhesion molecule in sea anemone epithelialization and gastrulation are just posted in the following preprint.

Here our latest work on how morphogens trigger tissue phase transitions to tune their own length-scales and time-scales - An exciting collaboration with @zhvas.bsky.social @dianakhorom.bsky.social Bernat Corominas-Murtra and heroic experiments by the incredible @cami-autorino.bsky.social @embl.org

The last part of @paulknabl.bsky.social 's PhD is now available at www.biorxiv.org/content/10.1...
Paul showed that BMP signaling is active in the diffuse nervous system of the sea anemone Nematostella and the box jellyfish Tripedalia. Moreover, suppression of BMP signaling in Nematostella leads...

Looking forward to catching up with you in Puerto Rico!

We thought we were just studying mesoglea biogenesis…Turns out Nematostella has been hiding a sophisticated backup pressure valve! Work driven by the talented PhD student Soham Basu! @embl.org‬ www.biorxiv.org/content/10.1...

Congrats, Joaquin!

Thanks, Joaquin!

The evolution of shape diversity through the lens of physics—explored in our new paper! A fruitful collaboration between our lab @EMBL, Salbreux’s lab @unige & others, led by @BailleulRichar1—now independent at @ENS_ULM—& Nicolas Cuny. bit.ly/3WRqdEa

EMBL scientists have used sea anemones to study how animals restore their shape following major injuries.

The results show how, in regenerating animals, systemic molecular and cellular changes help in regaining the original shape. 🪄
