Abstract:
Biological functions rely on ordered structures and intricately controlled collective dynamics. Such order in living systems is typically established and sustained by continuous dissipation of energy. The emergence of collective patterns of motion is unique to non-equilibrium systems and is a manifestation of dynamic steady states. The actomyosin cortex largely controls mechanical resilience of animal cells. Dynamic functions require transitions between different steady states of the cortex via biochemical regulation of the cytoskeletal components tuning the mechanics and stresses. At the same time, mechanical stresses can generate shape deformation or cytoplasmic flows, modulating the reaction-diffusion dynamics of biochemical processes inside the cells. In this talk I will describe our recent experimental effort in understanding the general mechanisms of such mechanochemical feedback, underlying the formation of self-organized spatiotemporal patterns both in model actomyosin cortices and in the starfish oocytes.
