This paper introduces cell systems as a new framework for the simulation of pattern and shape formation in two-dimensional cellular structures. Cell systems describe development in terms of lineage rules, with the orientations of division walls specified relative to a directional morphogenetic field. The shapes of cells result from mechanical cell interactions due to osmotic pressure and wall tension. Cell systems offer a highly intuitive method for describing the development of cellular structures, and capture their natural variability in a straightforward way. The concept is illustrated using abstract patterns and a developmental model of a fern gametophyte.
