Multicell ABM simulation environment. (Top Left) Simulation space where pixels containing Fn are represented by grayscale coloration (bottom right), and nine sub-cellular agents (blue) comprise a single simulated mesendodermal cell (bottom left). (Top Right) Sliders, buttons, and graphical outputs where the user can adjust parameter levels and quantitatively monitor emergent behavior, such as the Fn concentration and accumulation of polarity signals in space and time.
