Scientists at Harvard Medical School have succeeded in creating six chemical cocktails that can rejuvenate human cells in less than a week, without the need for genetic therapy and without damaging their identity. The results of the research have been published magazine Aging
The aging of the body is accompanied by the cessation of the cell cycle and the loss of its functions. As a result, wounds heal more slowly, skin and muscles lose their elasticity, and various age-related diseases occur.
According to scientists, this process can be reversed by expressing certain genes. However, this method is associated with risks to the body, for example, the appearance of cancer. Therefore, researchers are looking for other ways to stop aging.
In this study, the authors performed a large-scale screening of sets of molecules that can rejuvenate human cells. As a result, they identified six cocktails of chemical molecules that restore cell youthfulness in less than a week, without the need to introduce genetic material and without side effects.
“Until recently, the best we could do was slow aging. New discoveries show we can now reverse it. However, the process required genetic therapy, which previously limited its widespread use. Our discovery is to reverse aging with a single pill, from improving vision to effective treatment of numerous age-related diseases.” offers an opportunity,” the researchers said.
