Single and collective cellular oscillations involving the actomyosin cytoskeleton have been observed in numerous biological systems. We show here that a generic model of contractile material, which is turning over contracts against an elastic element, exhibits spontaneous oscillations. Such can thus account for shape amnioserosa cells during dorsal closure Drosophila embryo. investigate dynamics ensemble such oscillators relative contribution viscous friction losses yield different regimes Taking into diffusion elements, our theoretical framework predicts appearance traveling waves might propagation morphogenesis.
