Magnet helps target transplanted iron-loaded cells to key areas of heartWashington DC (SPX) Jul 03, 2012 Optimal stem cell therapy delivery to damaged areas of the heart after myocardial infarction has been hampered by inefficient homing of cells to the damaged site. However, using rat models, researchers in France have used a magnet to guide cells loaded with iron oxide nanoparticles to key sites, enhancing the myocardial retention of intravascularly delivered endothelial progenitor cells. Cell therapy is a promising approach to myocardial regeneration and neovascularization, but currently suffers f ... read more |
