Artificial ‘smart’ molecules that selectively target certain blood-vessel cells and prevent abnormal growth, appear to reduce reoccurring blockages in blood vessels previously opened by stents, while sparing healthy endothelial cells lining the blood vessel.One molecule studied prevented vascular smooth muscle cells from overgrowing and blocking blood vessels, and the other caused these cells to die.
