The normal blood vessel wall contains two functionally distinct types of vascular extracellular matrix, namely basement membranes and interstitial matrix. A basement membrane consisting of type IV collagen, the multi-adhesive glycoprotein, laminin, and a variety of heparan sulphate proteoglycans, surrounds all quiescent, contractile smooth muscle cells (SMCs). Basement membranes maintain the contractile phenotype, since plating freshly isolated SMCs onto type IV collagen or laminin retards transition to the activated, synthetic phenotype characteristic of vascular repair [1].
