Happy to share the work of a great collaboration on the study of the adult endoskeleton of echinoderms. To be discovered in Acta Biomaterialia (doi.org/10.1016/j.ac...)

Bizarre Creature With 'All-Body Brain' Challenges What We Know About Evolution of Nervous Systems What other animals have we underestimated?

Bizarre Creature With 'All-Body Brain' Challenges What We Know About Evolution of Nervous Systems

Single-nucleus profiling highlights the all-brain echinoderm nervous system A sea urchin is a head with a brain-like organization and a vertebrate-type retinal signature.

Proud to have been part of this very nice piece of work and this great collaboration. Congratulations to all. www.science.org/doi/10.1126/...

Congratulations to Oğuz Akar who was awarded the title of Doctor in Philosophy in Cell and Biology yesterday!

Sea urchin metamorphosis is maybe one of the most radical event in developmental biology. In just about an hour, these little pluteus larvae completely reorganize their entire body plan.

Very happy that this video got awarded an honorable mention by #NikonSmallWorld 😃

Congratulations to Lou Marchal, the new PhD student of the team, to have obtained a ministerial fellowship !!!!

Proud to have been part of this work. Congratulations to everyone!!!

β-catenin-driven endomesoderm specification is a Bilateria-specific novelty - Nature Communications Lebedeva et al. show that unlike Bilateria, the embryo of the cnidarian Nematostella specifies its endomesoderm in the β-catenin-negative domain. In contrast, subsequent β-catenin-dependent axial patt...

Tanya's @tclebedeva.bsky.social paper on endomesoderm specification in the beta-catenin-negative area of the Nematostella embryo is out! www.nature.com/articles/s41...

#Neuroplanete yesterday.

#Neuroplanete 2025. Today and tomorrow in Nice

For the #UNOC conference to be held in #Nice in June 2025

New production of baby sea urchins from December 2024

If you like snowflakes, check our new preprint about axial patterning in brittle stars ⭐

We looked at the expression of anteroposterior patterning genes in Amphipholis squamata juveniles, and compared it with existing data from other classes

Our work on the sea urchin adult nervous system will soon be presented in the context of the Neuroplanete 2025 program organized by the national journal #LePoint in Nice from March 6th to 8th. evenements.lepoint.fr/neuroplanete...

For a first post on Bluesky, I'm happy to share our work recently published in Plos Biology, on b-catenin and its multiple roles during sea urchin embryogenesis
