 Abstract: Dictyostelium discoideum (D.d.) is a valuable model organism to study self-organization and pattern formation in biology. Recently we reported flow-driven waves in experiments with uniformly distributed populations of signaling amobae, D.d., and carried out a theoretical study in a onedimensional model. In this work, we perform two-dimensional numerical simulations using the wellknown Martiel–Golbeter model to study the effect of the flow profile and intrinsic noise on the flowdriven waves.Weshow that, in the presence of flow, a persistence noise due to spontaneous cell firing events can lead to sustained structures that fill the whole length of the system.Wealso show that external periodic stimuli of cyclic adenosine monophosphate can induce 1:1 and 2:1 entrainments which are in agreement with our experimental observations.
