Using fluorescence live imaging and an in vitro implantation model, we show that human embryo attachment begins with direct cell fusion via syncytin-2–MFSD2A interaction.

🚨Seeking developmental or cell biologists🔬!🚨 Our department @ucl-cdb.bsky.social is looking to support scientists seeking to establish their lab with a fellowship. Deadline: 30 Jan. Apply here: www.ucl.ac.uk/work-at-ucl/...

Congrats to the leading author @agrigas.bsky.social!

❗PREPRINT ALERT❗ doi.org/10.64898/202... The lab of M. Lisa Manning at @syracuseu.bsky.social in collaboration with Ale Mongera at @ucl-cdb.bsky.social show that in the avian presomitic mesoderm, Contact Inhibition of Locomotion has a tissue-wide effect, making tissue act like a fluid under tension.

Contact Inhibition coordinating tissues made sparsely of mesenchymal cells. From Alex Grigas @ ManningGroup and @mongeralab.bsky.social www.biorxiv.org/content/10.6...

Super cool work spearheaded by the amazing @agrigas.bsky.social! Excited for this collaboration with @manningresearch.bsky.social and for everything still to come! 🎉 Also thank you to @emaniou.bsky.social and @glgalea.bsky.social for your help!

Very excited about this new paper out on bioRxiv, spearheaded by the fantastic Dr. Grigas in collaboration with @mongeralab.bsky.social and Galea labs.

Check out this new preprint on PSM mechanics! Very nice work!

How do sparse mesenchymal cells, with unique stellate arms spanning large gaps between cells, maintain their network while still flowing during development? In our new preprint we describe the avian PSM as a fluid under tension and develop new theory to explain it: www.biorxiv.org/content/10.6...

With more than 2.1k citations, 'The identification of genes with unique and essential functions in the development of the zebrafish, Danio rerio' by the CNV Lab highlighted the arduous work that took place during 'The Big Screen'. In total, 1163 mutants were described. #ZebrafishFunFacts 🧪

So called microtubule organizing centers (MTOCs) are not "organizing centers". They don't control their position (network center), nor MT orientation, length and shape (network shape). The actual organizers are MTs, molecular motors and regulators of MT +ends. MTOCs nucleate MTs. Let's rename MTOCs.

Thought I was being really novel when I designed and 3D printed this mold for zebrafish transplants based on the microinjection one, but found out today it already exists… Bottom: my PLA mold that’s bent from warm agarose Top: a very kind (more robust looking) gift from @mongeralab.bsky.social

How can we organize current theoretical approaches for developmental biology - from information to dynamical systems & GRNs - into a common framework? We propose to think along Marr's 3 levels: computational problem, algorithm, implementation Check out our review: arxiv.org/abs/2510.24536

Can pressure gradients persist over long timescales in animal cells? We induced intracellular pressure gradients and examined the resulting flows in single cells. We reveal surprisingly long lasting pressure gradients. More here: elifesciences.org/reviewed-pre...
