Initially in BiorXiv (www.biorxiv.org/content/10.1...) 1/12
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...

Ever wondered how to get a gastruloid to grow a head?

The Bulut-Karslioğlu lab figured out that by growing different stem cell aggregates in high and low oxygen and later assembling them, you can get gastruloids with a fully formed neural tube. Check out our "In preprints": doi.org/10.1242/dev....

Hi bsky!

Do embryonic tissues have backup plans🔀? Gastruloids (model of body elongation) can build an axis through different cellular mechanisms when on adherent substrates instead of free floating. A case of developmental plasticity!
