The central question in cell biology is how cells detect, interact and respond to extracellular matrix. The cell surface molecules, which mediate this recognition, consist of a lipophilic membrane domain and an ectodomain binding matrix materials. One group of this kind of molecules is the cell surface heparan sulfate proteoglycans (HSPG). This review summarizes recent information obtained on the cell surface PG of mouse mammary epithelial cells. The glycosaminoglycan containing ectodomain of this PG binds with high affinity Type I, III and V collagen fibrils and the C-terminal heparin binding domain of fibronectin. The PG is mobile on the cell surface, but can be immobilised by ligand binding. At the same time the PG associates with cytoskeleton and links the epithelial cytoskeleton to extracellular matrix. Thus the PG can mediate the changes in the matrix into changes in cellular behaviour, often seen during the regulation of cell shape, proliferation and differentiation. The cell surface PG is also released from the cell surface by cleaving the matrix-binding ectodomain from the membrane domain. Because of the binding properties of the ectodomain, this shedding may provide a means by which epithelial cells loosen their association with the matrix and with other cells, e.g., during normal epithelial development and the invasion of carcinomas.
