Genetic control of cell communication inC. elegans development

Cell communication is crucial for many aspects of growth and differentiation during the development of the nematode Caenorhabditis elegans. Two genes, glp-1 and lin-12, mediate a number of known cell–cell interactions. Genetic and molecular analyses of these two genes lead to the conclusion that they are structurally and functionally related. We summarize these studies as well as those involving the identification of other genes that interact with glp-1 and / or lin-12.
