Active flow of biological matter is important in many instances of animal development. Here I report on the physical mechanisms that underlie coordinated and large-scale flow of the actomyosin cellular cortex in the nematode Caenorhabditis elegans, which we revealed by a combination of experimental and theoretical investigations.
I discuss how this out-of-equilibrium material flow, through advection, switches a set of cellular proteins to a non-homogeneous distribution, which polarizes the cell. This highlights how active mechanics and cellular biochemistry interact to establish a biological pattern.
