From: Cellular automaton-based model for radiation-induced bystander effects
Schematic layout of the model of radiation-induced bystander-effects. a Two-dimensional cellular automaton composed of three types of grids : cell (green), medium (gray), and wall (black). b Four components of the simulation algorithm: (1) irradiation of the cells (black); (2) generation of bystander signals in the irradiated cells and diffusion of the signals to surrounding cells (red); (3) induction of cellular DNA damage induced by irradiation or bystander signals (purple); and (4) cellular response caused by DNA damage (white)
