Scientists have found the fountain of youth, after they have discovered scientific proof that injecting teens blood plasma into old bodies of mice does seem to like to give rejuvenation powers, revitalizing their physical activity and increasing cognitive capabilities. Scientists said the process could be used one day in treatments for humans.
"Young human plasma improves cognition," New Scientist quoted Sakura Minami from Alkahest company, as saying. "The blood of youth must have something in it that's important for keeping them young," she added.
In a new research, scientists took samples of blood plasma from a crowd of young, healthy 18-year-old teenage accomplices and then injected the blood to 12-month-old bodies of mice, which were in their middle age regarding mice years or equivalent to 50 years old regarding human years. These mice perform poorly on memory exams and move slower.
In three weeks, the teens' blood were injected into the mice twice in a week, which the researchers consider is accountable for its revitalizing properties. After three weeks, the mice were put in a series of tests.
Scientists from Alkahest, a biopharmaceutical company based in California, compared the behavior of treated mice to old and young control crowds of 12-month-old and 3-month-old untreated mice. They found out that teens' blood can rejuvenate old bodies - even if the old bodies are not human themselves.
The blood of the juveniles made the bodies of old mice act and moved like young again, with treated mice running all over in open areas just like their young ones. However, there was evidence also that their poor memories had significantly improved.
Scientists said that they saw a rejuvenation effect and that blood of teenagers improves cognition. Blood plasma contains salts, minerals, and some proteins, which could be the cause of the rejuvenating effect according to the scientists.
Though scientists have identified these proteins responsible for the rejuvenating power, they can't tell name them for now. However, they are willing to share that the blood injection stimulated neurogenesis, which means new nerve cells were born at the brains of treated mice. All the new neurons were situated at the hippocampus that plays a huge part in the creation of memories.
Thus scientists believe that teens' blood might help treat age-related mental weakening and even the Alzheimer's disease. To test this assumption, researchers have started a clinical trial at Stanford University including 18 people with moderate or mild Alzheimer's disease, according to Science Alert.
