Magnet Helps Target Transplanted Iron-Loaded Cells to Key Areas of Heart, INSERM Study

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. The study is published in a recent issue of Cell Transplantation (21:4), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/, “Cell therapy is a promising approach to myocardial regeneration and neovascularization, but currently suffers from the inefficient homing of cells after intracavitary infusion,” said Dr. Philippe Menasche of the INSERM U633 Laboratory of Surgical Research in Paris.
