Abstract：
:Cell adhesion occurs via a highly regulated set of sequential interactions. Prototypic components of a variety of adhesion cascades are discussed, including integrins, triggering molecules and lectin-carbohydrate interactions. Selectivity and efficiency are achieved by utilizing the right combination of multiple adhesion molecules and by their coordinated biochemical regulation.
