This great piece by @lionlchristiaen.bsky.social highlights the sea squirt Ciona as a versatile and tractable model for marine sciences, from cells to ecosystems 👏🧪 Read it in @natmethods.nature.com ⤵️ www.nature.com/articles/s41...
Well, we also find increased contractility in the aged embryo also correlates with faster compaction at the 8-cell stage. Could this be a possible metric to see which ones will implant?
Admirez la magie du développement cellulaire des organismes marins !

Our effort to extend genome editing across species just got a new member. This time, not a marine organism, nor a vertebrate, but the beautiful Dictyostelium discoideum and other Dictyostelids. In collaboration with van Gestel group

The "superpower" of sea urchins is the fact that a single female can produce millions of embryos. In the next day or so we will share a new method to analyze gene expression methods in these embryos using a fully automated, open platform.
