Fig. 2From: Cellular automaton-based model for radiation-induced bystander effectsDiffusion directions of the virtual signals. The diffusion-direction constants indicate the directions of signal diffusion through the medium-mediated pathway (MDP) and the gap junctional pathway (GJP). The virtual signal through the MDP diffuses into surrounding cell and medium grids. The virtual signal through the GJP diffuses into only surrounding cell gridsBack to article page
