Nano magnets guide stem cells to damaged tissue

Stem cells can be guided to injured areas of the cardiovascular system using magnetism, a group of UK scientists has shown. The technique, which involves labelling the cells with ferric nanoparticles, could help treat heart attacks and arterial injuries, and perhaps non-vascular conditions such as cancer.

The research team, from the Centre for Advanced Biomedical Imaging at University College London, used a magnet to attract human endothelial progenitor cells (EPCs) to the site of vascular injury in rats. These cells are known to be involved in physiological processes such as vascular re-endothelialisation and post-ischaemic neovascularisation.
