This paper introduces a strategy to program tissue shape transformations through nematic organization of cellular forces, demonstrating reproducible 3D shape generation upon tissue detachment.

The paper develops a continuum theory for curved epithelial shells by coarse-graining a 3D vertex model of active gel cellular surfaces, showing its accuracy in capturing buckling dynamics and the necessity of Cosserat theory for apicobasal tension asymmetry.

This study investigates the mechanics of epithelial buckling by combining experiments and simulations, revealing multiscale wrinkling dynamics and how they can be controlled through curvature and contractility.
