From fate to form: the journey to whole-embryo spatial transcriptomics - the Node Where molecules meet form I have long been interested in understanding how development emerges at the intersection of molecular and spatial organization.

From fate to form: the journey to whole-embryo spatial transcriptomics

In this 'Behind the paper' feature, @yinanwan.bsky.social shares the inside story of an ambitious journey with @schierlab.bsky.social & co.

Very grateful to everyone who made this work possible. I feel incredibly lucky to have worked with such an amazing team.

Special thanks to: Jakob El Kholtei, KJ Jenie, @mcolomerr.bsky.social, and of course our wonderful collaborator Bogdan Bintu and my mentor @schierlab.bsky.social

Whole-embryo spatial transcriptomics at subcellular resolution from gastrulation to organogenesis Gene expression patterns underlie development, but their systematic detection in whole embryos has remained elusive. We introduce a whole-embryo imaging platform using multiplexed error-robust fluores...

Very happy to see this out. πŸ‘ @yinanwan.bsky.social

I'm thrilled to announce that I'll be starting my lab as a SNSF starting grant professor at the Center for Integrative Genomics in Lausanne! I'm looking for PhD students who are fascinated about the neuronal basis of behaviour across species @fbm-unil.bsky.social

πŸ”₯ Piping hot; fresh from the oven! Fever-like conditions accelerate immune cell speed and efficiency through thermoregulation of actomyosin contractility. Congrats to Ivan Company-Garrido, @alempheius.bsky.social, and @mcolomerr.bsky.social on this huge collaborative effort.

And very excited from a personal note to share what started as a summer internship in 2018 in the Wieser and Ruprecht lab, and finished with my co-first author paper in DevCell ✨

With an in-vitro fast system, we found that even small temperature increases (1-2Β°C) are sensed by different immune cells. This rapid and reversible thermo-response depends on Myosin II activity, revealing a conserved thermokinetic mechanism for immune cell motility πŸ”₯

At low temperature, cells are weakly recruited with weak Myosin II activity and move slowly. At body temperature, recruitment and Myosin II activity are normal, giving normal cell speed. At fever-like temperature, recruitment and Myosin II activity are strong, resulting in fast cell movement.

Effective immune responses rely on efficient leukocyte migration, but how does temperature regulate this process?

Using #zebrafish embryos and mouse tissue explants, we show that temperature positively regulates leukocyte migration speed, exploration, and recruitment to wounds and lymph vessels πŸ”¬

Ever wonder what happens to immune cells when we get a fever? Exicted to share our paper showing that temperature regulates immune cell migration via myosinII! A wonderful collaboration with Ivan, @alempheius.bsky.social, @valeriaventurini.bsky.social & all co-authors!

We (schierlab.bsky.social and Seelig lab) are very happy to share that our work has found a home at DevCell cellpress.bsky.social! Free access here: authors.elsevier.com/sd/article/S...
What are the features in 5β€² UTRs that determine when and how much of a protein to make during embryogenesis?
