The Telomeres In The Human Body Can Be Replaced By New Substances. If The Human Life Span Is Realized, It Will Exceed 120 Years
In recent years, a team of researchers at the University of Chicago has gained global attention for the idea of extending the human lifespan by altering the way the telomeres of human cells work. Telomeres are structures at the ends of chromosomes in human cells, and their length is an important indicator of cell lifespan. In the past, it was believed that the length of telomeres was irreversible, but now, studies have shown that the telomeres of whole blood cells can replace the telomeres in organs, providing new possibilities for human life extension.
Telomere is a protective structure at the end of cell chromosomes, its length will continue to shorten as cells divide, and once shortened to a certain extent, it will lead to cell aging. In the human body, the limit of the number of divisions of telomeres is 52 times, that is to say, if there is no new substance to replace the existence of telomeres, the human life span will reach the limit at about 120 years old. A University of Chicago research team has found that telomeres from whole blood cells can replace telomeres in organs, opening up new possibilities for extending lifespan in humans.
At the same time, the length of telomeres is also different in different body tissues. For example, the telomeres of skeletal muscle do not shorten with age. This means that the concept of telomere length replacement provides a new way for humans to extend their lifespan. Although it is still in the research stage, its prospects are bright.
The study also caused some controversy. If telomeres can really be replaced, the average human life expectancy can reach about 120 years, which means that the problem of population aging will become more and more serious, and the allocation of social resources will also become a major problem. It is necessary to consider the rational distribution of social resources and population aging while pursuing life extension.
With the development of science and technology, the dream of extending human life is gradually becoming a reality. It is also necessary to seriously think about the social problems that all this brings, and find suitable solutions. In this process, it is necessary to follow the principles of scientific morality and ethics, to ensure the dignity and rights of human beings, and to make human life better.
