Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

A brief 🧵 (carried over from the old place)

Congrats!! Great story 🤩, and storytelling! 😄

Evolutionary repurposing of a DNA segregation machinery into a cytoskeletal system controlling cyanobacterial cell shape Bacteria, despite their diversity, use conserved cytoskeletal systems for their intracellular organization. In unicellular bacteria, the ParMRC DNA partitioning apparatus is well known for forming act...

One of the most exciting discoveries from our lab so far is now online as a preprint!

Read a story on how the ParMR and Min systems started to collaborate to create the CorMR cytoskeleton, which now controls cell shape in multicellular cyanobacteria:

Congrats Alex! 🥳 so great to see it with all these interesting additions!

Cadherins modulate the self-organizing potential of pseudo-embryos Gastruloids derived from ES cells mimic embryonic patterning through robust self-organization. Mayran et al. uncover that this competence depends on a cadherin switch regulated by Snai1-driven E-cadhe...

Happy to present the final version of our Cadherin and gastruloid manuscript, online at @cp-cellreports.bsky.social.

Very happy to share our latest work extending iterative immunofluorescence to in toto imaging of early zebrafish embryos (3D-4i), integrated with a 3D-dedicated image analysis pipeline! 🐟🔬📊
Huge kudos to Max Hess for this PhD milestone! 💪

Cell-cell contacts orchestrate tissue assembly and diverse cellular interactions.

🎯But what mediates their intricate patterns?🤔

Join me, @feyzanar.bsky.social, in exploring the interplay of adhesion and subcellular mechanics in contact patterning.

📢‼️ Exciting new preprint from the lab by @nikhil-mishra.bsky.social et al, now out on @biorxivpreprint.bsky.social, reveals that the early embryo geometry spatiotemporally patterns zygotic genome activation (ZGA) in zebrafish. 🐟 tinyurl.com/Biorxiv-nmis...
