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...)

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/...

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 😃

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...

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

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
