“Aged” cells removing can extend life by 20%

Large number of ballast cells accumulates in the body with age and increase in their concentration determines the risk of development of many age-related diseases, primarily cancer. Scientists from the Mayo Clinic College of Medicine (Minnesota, USA) conducted an experiment: they removed old cells from the mouse body, which led to an increase in the animal lifespan.

Studies showed that cells whose function deteriorates with age synthesize not only beneficial substances, but also compounds that damage healthy tissues - this is one of the key causes of the development of malignant tumors. To perform an experiment, scientists used genetically modified mice, in which exposure from the outside can start the apoptosis process - "self-digestion" of damaged cells. By introducing a special drug into the body of mature mice, scientists were able to destroy from 50 to 70% of ballast cells in different tissues of rodents.

Examination of animals showed that six months later, experimental mice were healthier than their counterparts who had not undergone the “molecular cleansing” procedure, they responded better to stress, the kidneys were more effective in eliminating toxic substances, etc. In addition, it turned out that cancer tumors were much less likely to occur, and life expectancy increased by an average of 20% in animals that underwent the procedure. At the same time, the experiment showed that cleansing the body of aged cells does not eliminate age-related changes such as memory impairment, decreased muscle strength, and coordination disorder. Therefore, the introduction of this technology into medical practice to remove old cells in people will not eliminate the need to lead a healthy lifestyle and maintain fading of mental and physical skills through regular training.
