Magnetic Attraction of Stem Cells Creates More Potent Treatment for Heart Attack
ScienceDaily (Apr. 10, 2010) — Researchers at the Cedars-Sinai Heart Institute have found in animals that infusing cardiac-derived stem cells with micro-size particles of iron and then using a magnet to guide those stem cells to the area of the heart damaged in a heart attack boosts the heart’s retention of those cells and could increase the therapeutic benefit of stem cell therapy for heart disease.
