According to Professor David Sinclair, a molecular biologist from Harvard, a technology has been developed to extend life to a hundred years using rejuvenating solutions. However, it has only been tested on rodents so far.
The team led by Sinclair began with rejuvenating the eyesight of elderly mice, and they managed to restore the retina that had degraded due to aging, which consists of neurons. This is significant as effective restoration of these cells could pave the way for complete brain rejuvenation.
The mice were given a special composition with enzymes capable of rejuvenating cells and even 'resetting' their age. The fluid is called the 'Yamanaka cocktail' in honor of the Japanese scientist and Nobel laureate who discovered the secret of unique tissue reprogramming.
Sinclair explains: both mice and humans can, over time, 'forget' how to function properly. This leads to various problems, whether it be wrinkles or age-related dementia. In other words, mammals experience aging due to a 'software glitch,' and Sinclair continues the analogy with computers, asserting that the body contains a 'backup' of youthful data. The Yamanaka composition helps activate it, making the cells young again.
Similar experiments were conducted in 2016 by Spanish researcher Juan Belmonte; however, at that time, alongside rejuvenation, side effects emerged, particularly the development of tumors. Sinclair adjusted the Yamanaka composition and eliminated this 'side effect' (at least in rodents).
The scientist plans to focus on other body parts of mice. As for humans as subjects of research, he speaks cautiously: much still needs to be thoroughly verified.
