Biologists have provided evidence that young blood, slows down aging

A group of American researchers from the University of California at Berkeley found out how young blood affects the body. Also, experts have found, what effect older blood could have on a young body. The effect, especially in the second case, was quick and quite noticeable.

For their study, researchers “combined” circulatory systems of two rodents of different ages, with the result that they partially “shared” blood. This is not the first experiment of this kind, however, previously obtained results have been somewhat less reliable professionals could not say with certainty what amount of blood exchanged experimental animals, and it was not entirely clear what changes are directly related to the exchange of blood, and which from the very fact that the two organisms were, in some sense, gathered together.

In the new experiments, experts have perfected the technology, having achieved that the number of transfused blood is easier to calculate, and the influence of external factors was minimized. As a result, in the body of the old mouse got about 50 percent of blood from young mice, and Vice versa.

Already one day after the start of the experiment, biologists have observed first results in aged mice slightly increased the rate of cell renewal in the muscles, and there were some other positive developments, indirectly indicating a temporary slowing of aging.

However, researchers are inclined to believe that the results are explained on “healing” and “anti-aging” properties of young blood, and, conversely, the harmful effects of blood old. This, according to experts, is the fact that the changes observed in the body in young mice, was more noticeable — their muscles began to age faster, and the scent and memory deteriorated.

In the future biologists, who published their study in the journal Nature Communications, hope to find out what the “old” blood provokes the acceleration of the aging process.
