Steering Stem Cells with Magnets
Magnets could be a tool for directing stem cells’ healing powers to treat conditions such as heart disease or vascular disease.
By feeding stem cells tiny particles made of iron oxide, scientists at Emory and Georgia Tech can use magnets to attract the cells to a particular location in the body after intravenous injection.
The results are published online in the journal Small and will appear in an upcoming issue.

The central nervous system (CNS) in most vertebrates forms initially as a flat sheet of cells, which subsequently rolls up and fuses shut to form the hollow neural tube, which is the precursor to the CNS. The enriched apical actin in the closing neural tube (shown in green in the image) is central to cell shape changes that contribute to the rolling up process.
