A new study from the University of California, San Francisco, has found that not all senescent cells
Scientists have observed these cells in lung tissue, as well as in other organs that serve as barriers in the body: the small intestine, colon, and skin.
The study showed that when using senolytic drugs that are designed to destroy these cells, damaged lung tissue healed more slowly.
Scientists believe that aging, senescentcells can detect damage in tissues and then respond to it by stimulating nearby stem cells to grow and repair damaged areas.
Previously, such cells were considered exclusively harmful.As people age, they accumulate senescent cells that can no longer divide to create new ones. However, they do not die, but continue to live. It was with them that the development of Alzheimer's disease, arthritis and other age-related diseases, as well as cancer, were associated. However, a new study shows that some "zombie" cells may be important to the body.
