- The flows of tissues of epithelial cells often involve neighbour exchanges called T1 transitions. Mechanically, they are irreversible rearrangements crossing an energy barrier. In this talk, I will deploy geometric constructions of classical Euclidean geometry to calculate this energy barrier for general, isolated T1 transitions dominated by line tensions. I will show how regularity of cell packings, tension fluctuations, and nonlinear tensions increase this energy barrier, providing the basis for coarse-grained understanding of cell neighbour exchanges in continuum models of epithelia.
