Ulcers on the backs of mice healed with the help of reprogrammed skin cells, according to a study published yesterday (September 5) in Nature. While superficial injuries heal when keratinocytes, the main kind of cells found in the outermost layer of skin, move into a wound and repair it, deeper cuts require help from medicine. By remodeling connective tissue cells within wounds into precursors of keratinocytes, the research team healed ulcers in living mice.
