How can we learn tissue mechanics directly from patterns and images?
In our new preprint, we introduce VertAX, a differentiable vertex-model framework in JAX for simulating epithelia, inferring parameters, and designing target tissue behaviors.

Very happy to have this work finally published! How do embryos sculpt their shape? We map the contractile & adhesive forces shaping early C. elegans embryos.
With K. Yamamoto @Kazu_YAMAMOTO4 G. Charras' lab and my team

A central result: cadherin-dependent adhesion contributes significantly to cell-cell tension in C. elegans, with a highly non-linear, Hill-like dependence. Adhesion is not just a small correction to contractility.

Very excited to be sharing our new paper, just out in Nature Cell Biology! nature.com/articles/s41556-0…
The big question we investigate: How do migrating cells put their front 🔴 and back 🔵 in the right place?

Beyond synthetic benchmarks, we show applications to mechanical parameter inference from microscopy images and to inverse design problems in epithelial tissues. 4/5

We hope VertAX can help make inverse problems & differential programming more accessible in tissue mechanics.
Thanks to @appasqui, @MaxenceErnoult, Italian colleagues, & other members of the team for this collaboration.
Comments very welcome.

If you think the next big idea in your field will come from inside the field, you're probably wrong.

We recapitulate our findings in a mathematical model and show that this creates a feedback loop, where the front and back communicate through mechanical signals. @virtual_embryo @andreu_gallen
It ensures that the cell can move forward in a coordinated way.
