By Andy Coghlan MAGNETS are being used to control the transformation of stem cells into specific tissues. They could also be used to guide stem cells to target locations in the body, allowing arthritic joints and torn cartilage, for example, to be repaired without surgery. Alicia El Haj of Keele University, UK, and her colleagues have created magnetic beads up to 2 micrometres across that bind to receptors on human mesenchymal stem cells, which are extracted from bone marrow or fat tissue. When a magnetic field is applied, the beads move,
