New products are being developed, and plenty of studies are being conducted on various ways to reduce ageing and its effects. A recent study conducted in mice in the Stanford University claims that injecting young blood in older individuals may promote healthy brain function, thereby reducing the risk of Alzheimer’s and other age-related illnesses, and significantly reducing visible effects of ageing. It is also thought to aid the development of new synapses and revitalize brain tissue.
Saul Villeda of Stanford University presented results which suggest that it is indeed possible to enhance brain function and rejuvenate the brain of old animals by injecting them with the blood of the young.
The experiment involved connecting the circulatory systems of an old and a young mouse, to introduce the young blood into the system of the ‘old’ mouse. The old mouse was kept under observation for several days, after which, it was found that the old mouse demonstrated clear signs of reversed ageing. A whopping 20% increase in the connections between brain cells was noted, and an increase in the number of stem cells was observed. It is presumed that the regenerative effects of young blood outweigh the degenerative effects of old blood, which promotes age reversal.
On the other hand, injecting old blood may have detrimental impact on the young mouse, due to the inflammatory action of plasma proteins.
The above study is not yet published and has been done only in rodents. A number of factors will have to be taken into account before this procedure is considered in humans. You will thus have to wait sometime to inject ‘young’ blood into your great granddads and grannies for now.
