Pseudostratified epithelia have irregular cell shapes along the apical-basal axis, which are determined by fundamental geometric relationships that minimize lateral cell-cell contact energy. This understanding provides a new perspective on epithelial cell organization and can be utilized in the development of 3D simulation frameworks for studying epithelial dynamics.
Pseudostratified epithelia have smooth apical and basal surfaces, yet along the apical-basal axis, cells assume highly irregular shapes, which we introduce as punakoids. They interact dynamically with many more cells than visible at the surface. Here, we review a recently developed new perspective on epithelial cell organisation. Seemingly random at first sight, the cell packing configurations along the entire apical-basal axis follow fundamental geometrical relationships, which minimise the lateral cell-cell contact energy for a given cross-sectional cell area variability. The complex 3D cell neighbour relationships in pseudostratified epithelia thus emerge from a simple physical principle. This paves the way for the development of data-driven 3D simulation frameworks that will be invaluable in the simulation of epithelial dynamics in development and disease.
