Controlling Cell Behavior with Magnets

January 18, 2008 | Source: Technology Review

Harvard Medical School researchers have demonstrated a means of controlling cell functions with a physical, rather than chemical, signal.

Using a magnetic field to pull together tiny beads targeted to particular cell receptors, Harvard researchers made cells take up calcium, and then stop, then take it up again. It could lead to a totally new class of therapies that rely on cells themselves to make and release drugs.
