This review focuses on the vascular smooth muscle cells present in the medial layer of the blood vessels wall in the fully differentiated state (dVSMCs). The dVSMC contractile phenotype enables these cells to respond in a highly regulated manner to changes in extracellular stimuli. Through modulation of vascular contractile force and vascular compliance dVSMCs regulate blood pressure and blood flow. The cellular and molecular mechanisms by which vascular smooth muscle contractile functions are regulated are not completely elucidated. Recent studies have documented a critical role for actin polymerization and cytoskeletal dynamics in the regulation of contractile function. Here we will review the current understanding of actin cytoskeletal dynamics and focal adhesion function in dVSMCs in order to better understand actin cytoskeleton connections to the extracellular matrix and the effects of cytoskeletal remodelling on vascular contractility and vascular stiffness in health and disease.
