The role of the extracellular matrix in arterial remodelling.
The extracellular matrix is now recognized as a biologically active and dynamic composition of structural, adhesive, and counteradhesive fibrous proteins embedded in a hydrated ground substance of glycosaminoglycans and proteoglycans. The ability of resident cells to detect small differences in the specific combination, concentration and distribution of matrix components suggests that perturbation of the homeostatic matrix can lead to remodelling following angioplasty. Recent studies reviewed herein have focused on how alterations of the relative composition of matrix components ultimately leads to changes in cell growth, behaviour and differentiation, all of which can significantly contribute to remodelling of the vascular wall following injury. These cell-matrix interactions may provide novel therapeutic targets in the prevention of unfavourable remodelling that leads to restenosis.
