In order to study the growth and development of cellular systems one needs a formalism in which one can combine the biophysical properties of cells with the modulation of these properties by gene regulatory processes. I will argue that the multiscale CA formalism now known as the Cellular Potts Model (CPM) provides a simple yet basically sound representation of a biological cell, which can be interfaced with gene regulatory processes. It represents a cell as a highly deformable object which takes its shape from internal and external forces acting upon it. I will demonstrate how within this formalism complex large scale morphodynamic processes can result from local regulation of cell, and in particular membrane, properties. I will explain morphogenetic mechanisms which tend to evolve in such systems.
