A naturally occurring hormone protects the brains of baby mice from post-natal brain damage caused by a lack of oxygen. Epidermal growth factor  stimulated the regrowth of brain cells that were killed or damaged. In humans babies born before the 32nd week often have under-developed lungs and are unable to get enough oxygen to their brains, which can result in the development of conditions like cerebral palsy.

However, many growth factors can trigger the development of tumours as well as stimulating the regrowth of dead cells, so transfer of this approach to humans may be some way off.

"It was really amazing," says Vittorio Gallo, of Children's National Health System in Washington, D.C. "These mice looked identical to the mice that were not exposed to the injury."
