Epithelia – a population of cells that are organized into coherent tissues, that have well established CAM patterns; as well as a stable pattern of substrate adhesion between the cells and the extracellular matrix. Mesenchyme – a population of cells that are loosely associated and migratory, that have retracted (or localized) their CAM and SAM molecules such that they can follow homophilic and heterophilic gradients within other cell populations of the embryo.
