Abstract
Recently it has become clear that integrins and other adhesive receptors play an important role in the control of cell growth and differentiation. In various cell types, anchorage to the extracellular matrix via integrins strongly influences the ability of the cell to respond to soluble mitogens or to differentiation factors. Thus adhesive receptors must generate signals that influence cell behavior. Some of the pathways of adhesion receptor signaling are now beginning to be worked out, but there is still much to learn. In particular, the mechanistic basis for the cooperation between anchorage signals and signals from soluble growth and differentiation factors remains ill‐defined. This review will examine some of the current information linking adhesion receptors to control of mitogenesis and differentiation.
