86-year-old man achieves 'reverse growth'! Stanford scientists: injecting young blood can return to youth
In an episode of the TV series "Silicon Valley", in order to return to his youth, the billionaire Gavin signed a contract with an 18-year-old young boy to buy his "fresh blood" at a high price, and regularly transferred the blood Input into their own body, in order to ensure "quality", young boys need to not drink alcohol and stick to fitness.
What is even more incredible is that this seemingly fantastic technology has actually appeared many times in reality, and it has even been confirmed by a number of sciences: exchange transfusion therapy can restore the body to rebuild. With the disclosure of related experiments, those "not old" assumptions seem to be gradually becoming reality.
Scientists find the key to rejuvenation of "exchange blood": regulation of cellular aging
Recently, Professor Tony Weiss from Stanford University's Department of Biology led his team to conduct a "exchange blood" experiment. Researchers injected more than 100 old people over 86 years old with the plasma of young people under 30 years old. Reaction, cognition, operation and other abilities have been improved to varying degrees, and human aging indicators such as skin condition, muscle, metabolism, etc. have also been significantly improved, blood vessel elasticity has increased by 64%, and hearing has increased by 27%.
Coincidentally and alone. On May 24 this year, a team from the Institute of Zoology of the Chinese Academy of Sciences published a new study in the international academic top journal "Cell" saying that through "exchange blood", senile mice can achieve autonomy in seven organs such as the brain, liver, and bones. Rebuild.
In the experiment, scientists let 2-year-old mice (about 60 to 70 years old in humans) share blood in a circulatory system with young mice, and then found that the former had reduced aging symptoms and appeared "reverse aging", while the latter accelerated Ageing. This scene sounds quite a bit like the old witch in the fairy tale sucks blood to become a girl.
In order to decipher the principle of "exchange transfusion", the scientists also conducted further discussions. Through data analysis of cell communication and gene expression, they found that the "manipulators" in the experiment were actually aging regulators: YY1, CCL3 , These two components can help hematopoietic cells return to their youthful state, thereby revitalizing the entire hematopoietic system and even the body.
The announcement of this series of research results shocked the scientific community. They not only affirmed that "replacement of young blood can indeed return to youth", but also pointed out to people a new way of guiding the regeneration of cells throughout the body with the help of newly discovered aging-regulating substances. .
"Pandora's box"? or will have endless troubles
However, people have to admit that although many scientists have confirmed that allogeneic exchange transfusion can delay the aging of organs, this method is difficult to be accepted by the public, and the specific implementation of application to the human body is also very difficult. Powerful control may become a "Pandora's Box" and exacerbate the social contradiction between the rich and the poor.
In addition, there are risks of rejection and concurrency that may occur in exchange operations, which have led to the controversy over "exchange blood therapy". It has also been expressly banned by some countries. In comparison, some people prefer scientific intervention methods.
Also in order to delay the aging of the human body, different from the madness of "exchange blood therapy", Professor David of Harvard Medical School proposed a more feasible "WLife" life technology. This new technology has been known as "WLife". In the experiment, after 22-month-old mice ingested the substance for a week, the mitochondrial function was reversed to 6 months, which is equivalent to about 60-year-olds "returning" to 20-year-olds. body condition.
The reason is that WLife can stimulate the potential vitality of mitochondria and continuously supply energy to cells, thus helping them maintain their youthful state. At present, this substance has been listed as a key scientific research project by countries in Europe and the United States, and China relies on "Wright Health". After biotech companies settled in Ka-Dong, T-Mall and other channels, WLife quickly became popular among the elderly in first- and second-tier cities. Even real estate tycoons Li Chaoren and Pan have publicly stated that the effect is very good. This method is obviously It is more gentle and reliable than the "exchange blood" method.
Future scientific development challenges the shackles of life
Time may be the only fair resource in the world, but today, "borrowing from the sky for another five hundred years" seems to have become an exclusive game for the rich and famous. One of the tens of thousands of "bigu" courses popular in the rich circle, this kind of "burning money", ordinary people can only say: laugh and don't talk.
A hundred years ago, the average human life expectancy was in the 40s. Now, with the continuous development of modern medicine, this figure has increased to the 70s. The "aging intervention" that was often regarded as a heresy before has also become a scientific field. Popular research track. In the "Top Ten Outstanding Technologies in 2020" selected by MIT, anti-aging substances such as WLife were also selected, which means that this type of life technology has been recognized by the public and is gradually becoming orthodox.
The cover of "Time" in 2015 boldly predicted: With the help of rapidly advancing scientific research, human intervention in aging is no longer "a fantasy", but a contest between human technology and the natural laws of aging, disease and aging. We will become more and more influential in this matter.
Maybe in the near future, as Professor David said: "Aging will be like a cold, which can be prevented and treated." I hope that at that time, every ordinary person can benefit from it.
