Novel approach for endothelializing vascular devices: understanding and exploiting elastin-endothelial interactions.

Elastin is an essential component of arteries which provides structural integrity and instructs smooth muscle cells to adopt a quiescent state. Despite interaction of endothelial cells with elastin in the internal elastic lamina, the potential for exploiting this interaction therapeutically has not been explored in detail. In this study, we show that tropoelastin (a precursor of elastin) stimulates endothelial cell migration and adhesion more than smooth muscle cells.
