Diffusion, Reaction, and Biological pattern formation (continued 3 of 3)

Here I return the pattern-formation discussion to the context of symmetry breaking and chemical patterns of GTPases such as Cdc42, Rac and Rho in cell polarization. I explain the spatial context of GTPase distributions in a stimulated chemotactic cell and derive the system of partial differential equations (PDEs) for these. These examples motivate the usefulness of LPA as an additional tool in testing for pattern formation and polarizability.
