Combining Antibodies, Iron Nanoparticles and Magnets Steers Stem Cells to Injured Organs
Cedars-SinaiResearchers at the Cedars-Sinai Heart Institute infused antibody-studded iron nanoparticles into the bloodstream to treat heart attack damage. The combined nanoparticle enabled precise localization of the body’s own stem cells to the injured heart muscle. The study addresses a central challenge in stem cell therapeutics: how to achieve targeted interactions between stem cells and injured cells.
