Chemotaxis Control of Transient Cell Aggregation.
Chemotaxis affords motile cells the ability to rapidly respond to environmental challenges by navigating cells to niches favoring growth. Such a property results from the activities of dedicated signal transduction systems on the motility apparatus, such as flagella, type IV pili, and gliding machineries. Once cells have reached a niche with favorable conditions, they often stop moving and aggr...
متن کاملModel Hierarchies for Cell Aggregation by Chemotaxis
We present PDE (partial differential equation) model hierarchies for the chemotactically driven motion of biological cells. Starting from stochastic differential models we derive a kinetic formulation of cell motion coupled to diffusion equations for the chemoattractants. Also we derive a fluid dynamic (macroscopic) Keller-Segel type chemotaxis model by scaling limit procedures. We review rigor...
متن کاملA computational model of chemotaxis-based cell aggregation
We present a computational model that successfully captures the cell behaviors that play important roles in 2-D cell aggregation. A virtual cell in our model is designed as an independent, discrete unit with a set of parameters and actions. Each cell is defined by its location, size, rates of chemoattractant emission and response, age, life cycle stage, proliferation rate and number of attached...
متن کاملA Computational System for Investigating Chemotaxis-Based Cell Aggregation
We have developed a software system that simulates chemotaxis-based cell aggregation in 2D. The model implemented within the system consists of such cell behaviors as chemical diffusion/detection, motility, proliferation, adhesion and life cycle stages. Each virtual cell detects the state of the environment, and responds to the environment based on a pre-defined “program” and its own internal s...
متن کاملSubdiffusion, chemotaxis, and anomalous aggregation.
We propose a nonlinear random walk model which is suitable for the analysis of both chemotaxis and anomalous subdiffusive transport. We derive the master equations for the population density for the case when the transition rate for a random walk depends on residence time, chemotactic substance, and population density. We introduce the anomalous chemotactic sensitivity and find an anomalous agg...
