Research investigates electricity in wound healing

An international team of scientists has discovered two genes that enable cells to respond to electrical signals in the body to heal wounds. They also showed that by applying an electrical field to a wound they could change the movement of cells and speed up the healing process. "Our studies show that electricity in the body is far more important than previously thought and that it has significant potential in wound healing and possibly also regeneration," said Professor Min Zhao, of the University of Aberdeen in Scotland, who headed the research team.
