Allometric spreading and focal adhesion collective organization are coordinated by cell-scale geometrical constraints

This study shows that focal adhesion density remains constant across different cell sizes and geometries, adapting through changes in cell shape and contact area.

Disentangling the contributions of stress fibres and the unbundled actin meshwork to the anisotropy of cortical tension in response to cell shape

This study quantifies how cell shape influences cortical tension anisotropy by separating contributions from bundled and unbundled actin structures.

Embryo-scale epithelial buckling forms a propagating furrow that initiates gastrulation

The paper shows that tissue-scale force balance, not cell-autonomous shape changes, drives epithelial buckling and initiates gastrulation in Drosophila embryos.

Geometry can provide long-range mechanical guidance for embryogenesis

The paper models how geometric features of the Drosophila embryo guide tissue-scale deformations through actomyosin contractility.
