Epithelial cells are characterized by their remarkable capacity to organize themselves into polarized, adherent tissue. Morphological changes that accompany cellular growth and division can potentially be extremely disruptive to epithelial homeostasis (akin to building a wall with differently sized bricks). I am applying my expertise in single cell mechanics in the context of tissue to understand how rapidly proliferating epithelial layer reconciles with the drastic shape changes associated with cell division.
