The paper investigates mechanical instability in bladder epithelium at cancer onset, showing stiffness changes and morphological features similar to early tumors.

The paper uses light-sheet microscopy and physical theory to study 3D cell organization in growing mouse embryonic lung epithelia, finding that cell packing follows physical laws despite dynamic changes.

The paper shows that Aboav-Weaire’s law in epithelia arises from minimizing lateral contact surface energy by controlling angles in polygonal lattices, alongside topological constraints.
