We present results of experiments on the dynamics of Dictyostelium discoideum in a novel setup which constrains cell motion to a plane. After aggregation, the amoebae collect into round “pancake” structures in which the cells rotate around the center of the pancake. To provide a mechanism for the self-organization of the Dictyostelium cells, we have developed a new model of the dynamics of selfpropelled deformable objects. In this model, we show that cohesive energy between the cells, together…

Possible role of contact following in the generation of coherent motion of Dictyostelium cells.

A mathematical model is presented to explain both aggregation and coherent motion of cells in two-dimensional space of Dictyostelium discoideum and it is shown that with contact following, cells form circular clusters within which cell rotation occurs.

Modeling Self-Propelled Deformable Cell Motion in the Dictyostelium Mound; a Status Report

This report describes recent attempts to generate a computational model which can address collective cell motion and self-organization in the multicellular State of Dictyostelium and to thereafter apply it to some recent experimental findings.


We present particle-based simulations for the flocking behavior of self-propelling particles. Built upon previous models, our models include realistic but simple rules for the self-propelling, drag,

Soft deformable self-propelled particles

It is demonstrated that this deformation alone can induce alignment of the velocity vectors, and this reflects the reentrant fluid behavior of the general Gaussian-core model now applied to a self-propelled system.

Swarming Patterns in a Two-Dimensional Kinematic Model for Biological Groups

A continuum model for the motion of biological organisms experiencing social interactions and study its pattern-forming behavior, which takes the form of a conservation law in two spatial dimensions.

Multi-scale organization in communicating active matter

This work shows the formation of complex structures at multiple scales amongst interactive agents that locally process information transmitted by chemical signals, providing insights into the role of self-sustained signal processing for self-organization in biological systems and open routes to applications using chemically driven colloids or microrobots.

Swarming patterns in Microorganisms: Some new modeling results

The derivation of a reaction-diffusion equation capable of dealing with chiral branching and the introduction of a new flocking model to study cell-sorting in localized vortices are presented.

This work uses a variant of the Vicsek model that includes pairwise repulsive interactions to describe the collective behaviour of self-propelled particles and suggests that in certain parameter ranges they observe collectively migrating clusters that arrange in an approximately hexagonal way.

The synchronization mechanism of oscillatory production of cyclic adenosine 3′,5′‐monophosphate in Dictyostelium is discussed in detail to show how it is a universal feature that can explain synchronization in other organisms.



A Hydrodynamic model forDictyostelium discoideumMound Formation

The model can stimulate the whole early process of development from isolated single cells, formation of bifurcating aggregation streams and formation of a three-dimensional aggregate with a single set of parameters and mimic alternative modes of morphogenesis frequently observed after disturbance of cAMP signalling or cell motility by chemicals or mutations.

Modelling Morphogenesis: From Single Cells to Crawling Slugs.

A three-dimensional hybrid cellular automata (CA)/partial differential equation (PDE) model is presented that allows for the study of morphogenesis in simple cellular systems and causes the amoebae to spatially self-organize.

By adding spatial and temporal noise to the levels of an important regulator of external cAMP levels, the cAMP phosphodiesterase inhibitor, this work can explain the natural progression of the system from randomly firing cells to circular waves whose symmetries break to form double- and single- or multi-armed spirals.

Streaming instability of slime mold amoebae: An analytical model

A unifying interpretation of the streaming instability as a cAMP wave-driven chemotactic instability is proposed and a simple, analytically tractable, model of Dictyostelium aggregation is developed to test this idea.

Dictyostelium discoideum: cellular self-organization in an excitable biological medium

Numerical simulations of the model show quantitatively how signal relay, chemotactic movement and adaptation orchestrate the collective modes of cell signalling and migration in the aggregating cell layer of the slime mould Dictyostelium discoideum.

This work has developed a model in which the cells are treated as discrete points in a continuum field of the chemoattractant, and transduction of the extracellular cAMP signal into the intracellular signal is based on the G protein model developed by Tang & Othmer.
