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.

Latest paper

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. Check out our recent work here:

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.

Depletion of a neural cell adhesion molecule disrupts both epithelial and germ layer identity in sea anemone embryos
Assembly of cells into epithelial layers marks the early steps of tissue organization and embryonic development in most animals. Although several conserved proteins are known to be essential for epith...

The anti-neural role of BMP signaling is a side effect of its global function in dorsoventral patterning
In Bilateria with centralized nervous systems (e.g. in vertebrates or arthropods), the minimum of the BMP signaling activity gradient defines the position of the central nervous system. BMP-dependent ...

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 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. 🪄
