London: A stem cell jab given within half an hour of a stroke may aid in recovery from the fatal condition, a new study claims.Researchers found that rats injected with stem cells 30 minutes after a stroke had almost normal brain function restored within a fortnight.The Bolivian research team said the method has potential in human trials.Current practices involve treating patients with "clot-busting" drugs in the "golden hour" after a stroke has taken place.The study adds to other research which found that stem cells could aid stroke patients by boosting the body`s ability to repair tissue damage.Stem cells are the body`s "master cells", with the potential to become many different cell types, and theoretically replace cells lost through disease or injury.Recent tests in humans have shown some promise, with stroke symptoms improving after an infusion of stem cells.
