Summer break prevented me from properly advertising this serie of reviews on the function of cell death during development that I edited. There is still a lot to dig in regarding regulation of apoptosis in vivo ad I hope we managed to illustrate this well

Thrilled to share the first story from my postdoc! 🎉 A wonderful experiment + simulations collaboration. In the Drosophila wing, we find that 3D cell shapes affect signalling range and fine-tune developmental patterning www.biorxiv.org/content/10.1... Thread below ⬇️

Check out this work from @gserranonajera.bsky.social and Apolline Delahaye! They show how gastruloids can employ different morphogenetic strategies to set up a body axis. It nicely builds from Guillermo’s PhD work recapitulating gastrulation modes in the chick: www.science.org/doi/10.1126/...

We study how tissues regenerate - and use those principles to build 3D tissues in vitro.

We’re also grateful to the Editor and Reviewers for their helpful feedback. We hope this study contributes to a deeper understanding of how cells regain their place in a regenerating organ.
Thanks for reading! 🙌

We propose that this velocity results from a proximalisation force, derived from a proximalisation potential. This gives us a quantitative, testable framework to study a central mechanism of regenerative patterning.

By fitting our model to the data, we inferred—for the first time—the proximalisation velocity (vp): how fast cells shift identity from distal to proximal!

Osvaldo Chara @osvaldo-chara.bsky.social · Jul 25

To interpret the data, we developed a reaction–diffusion–advection (RDA) model. This allowed us to describe proximalisation as a velocity field resulting from changes in positional cues due to Tig1/Prod1.
