These images show live embryos of animals (jellyfish, crustacean, worm, sea urchin, sea squirt, beetle) and one of animals closest single-celled relatives. They were captured taking advantage of fluorescent proteins localised on the outer membrane of cells, allowing us to observe cell outlines. 1/9

Mapping nerves in a whole embryos.
We find that across species and development stages, embryonic nerves display (beautiful) fractal geometry.

It's difficult to succinctly summarize a entire germ layer, but Aaron Zorn, Scott Rankin and I tried recently!
Our "Endoderm at a Glance" review with @dev-journal.bsky.social is out now.

Earthset from Artemis II. I am overcome.
New paper! Self-generated gradients in macrophage chemotaxis. Just published, by the esteemed Abhi Kiran and many collaborators.
A short skytorial follows.

Our latest manuscript on (Harry Potter and) the effect of elevated temperature on embryonic development in flies. Even a small increase in temperature causes developmental defects, indicating problems in the face of global warming! www.nature.com/articles/s41...
🥳 I am happy to share our latest manuscript published in @natcellbio.nature.com We use #Gastruloids to study #CellCompetition during early mammalian development and find not only that this is highly pronounced in our system but also tightly restricted in time. (1/12) www.nature.com/articles/s41...

Macrophages don’t just follow chemoattractants to locate sites of infection, they can also create and sculpt them as guidance cues but the mechanisms remain unclear. This study shows that macrophages ...

Kale et al. show that nuclear divisions are defective at elevated temperature, leading to gastrulation defects and embryo lethality. Their work finds that F-actin – microtubule interactions during mit...
Frenster et al. utilize mosaic mouse gastruloids as a model of cell fitness and competition, identifying a temporal window between primed pluripotency and early gastrulation during which cell competit...
