three forms of cell adhesion determine the life cycle ofDictyostelium: i) adhesion of bacteria to the surface of the growing amoebae, as the prerequisite for phagocytosis;ii) cell-substrate adhesion, necessary for both locomotion of the amoebae and migration of the slug;iii) cell-cell adhesion, essential for transition from the unicellular to the multicellular stage. Intercellular adhesion has received the most attention, and fruitful approaches have been developed over the past 25 years to identify, purify and characterize cell adhesion molecules. The csA glycoprotein, in particular, which mediates adhesion during the aggregation stage, is one of the best defined cell adhesion molecules. The molecular components involved in phagocytosis and cell-substratum adhesion are less well understood, but the basis has been laid for a systematic investigation of both topics in the near future.
