Expression of caveolae on the surface of rat arterial smooth muscle cells is dependent on the phenotypic state of the cells.

Abstract excerpt

Both after vascular injury and when established in vitro, arterial smooth muscle cells pass through a characteristic change in phenotype. This process includes a prominent structural reorganization with partial loss of myofilaments and formation of a large endoplasmic reticulum and Golgi complex. As a result, the cells lose their contractility and become able instead to divide and to secrete extracellular matrix...
