Il cherche à comprendre la stabilité de cette molécule, "facteur" de transcription pour le contrôle du destin cellulaire (différenciation des cellules : par ex. tissu nerveux ou épiderme...)

Cette manip. récurrente n’a cette fois pas un but de recherche mais va servir à des tests en vue de l’achat d’un nouveau microscope confocal.

Cathy Sirour @biodev-vlfr.bsky.social prépare des embryons d’ascidie Ciona intestinalis pour détecter in situ l’ARNm Otx codant pour une protéine qui détermine les cellules à l’origine des neurones.

Meet the veliger larva - a tiny ocean drifter with a delicate shell and two ciliated “velums” that look like fluttering ears. These velums help it swim through plankton and capture food.

Bryozoan coronate larva…or man in the moon?

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... 🧵
There are still plenty of Ascidian sea squirt larvae on my plankton samples at the moment. Love them!

🚨 My lab is hiring at all levels!
Interested in animal origins & evolutionary cell biology?
I'm recruiting a postdoc, PhD students & a research assistant to study the molecular evolution of cell adhesion using marine invertebrates + comparative genomics.

Incredible pictures by @alexandrejan.bsky.social, ctenophore whisperer in the @pawelburkhardt.bsky.social lab 😍 Happy belated ctenophore day! 🌈
I hope to take a PhD student in 2026 to study siphonophores. Please reach out if you are interested in applying this fall. For examples of recent lab projects see www.sciencedirect.com/science/arti... and academic.oup.com/gbe/article/...
Just a single comb jelly (Ctenophora) larva in this weekend’s sample.

🪼 How did the animal body plan evolve?
This ‘fundamental’ study in Clytia sheds light on how Wnt3 coordinates both gene expression and planar cell polarity during axis formation, offering key insights into the origins of morphogenesis.
