Taking a big leap towards finding a treatment of vascular diseases, a team led by an Indian-origin scientist at the Gladstone Institute of Cardiovascular Disease (GICD) has discovered a key switch that makes stem cells turn into the type of muscle cells that reside in the wall of blood vessels. Dr. Deepak Srivastava’’s study claimed that the same switch could be used in the future to limit growth of vascular muscle cells that cause narrowing of arteries leading to heart attacks and strokes, limit formation of blood vessels that feed cancers, or make new blood vessels for organs that are not getting enough blood flow. It was found that a tiny RNA molecule, called microRNA-145 (miR-145), not only had all the information necessary to turn a stem cell into a vascular smooth muscle cell (VSMC), but could also affect VSMCs in the...
