Abstract_ Background A significant body of literature is devoted to modeling developmental mechanisms that create patterns within groups of initially equivalent embryonic cells. Although it is clear that these mechanisms do not function in isolation the timing of and interactions between these mechanisms during embryogenesis is not well known. In this work a computational approach was taken to understand how lateral inhibition differential adhesion and programmed cell death can interact to create a mosaic pattern of biologically realistic primary and secondary cells such as that formed by sensory primary and supporting secondary cells of the developing chick inner ear epithelium. Results Four different models that interlaced cellular patterning mechanisms in a variety of ways were examined and .
