    breakthrough lets the elderly cells "cross" back to their youth. British scientists simply added a chemical to senescient cells in their labs, revitalised the inactive cells, regained their ability to divide cells at a young age, and the telomeres on chromosomes longer again, Physicists.
    With age, tissues and organs in the body become more susceptible to disease, an important reason being that a large number of accumulated senescies lose the ability to continue dividing and growing and, more importantly, that these aging cells are no longer able to regulate their internal genes at all. When a cell performs a task, each gene in it sends out multiple signals, and a specific gene, the shear factor, identifies the correct instructions from those signals to guide the cell to respond correctly to external stimuli. Therefore, the shear factor plays a vital role in ensuring that the gene plays all functions, but as people get older, the number of shear factors in the cells becomes smaller and smaller, the efficiency of work is greatly reduced or even completely lost function, so that the cells lose the ability to stress their surroundings.
    , professor of molecular genetics at the University of Exeter in the UK, has previously shown that shearing factors can be gradually turned off during aging. In the new study, Harris' team proved once again that adding chemicals can re-open these shear factors and restore cell regeneration. They added resveratrol similars naturally extracted from red wine, dark chocolate, red grapes and blueberries to aging cells, and just a few hours after they were added, the cells showed younger features in their appearance and behavior, began to divide again, and telomeres began to grow longer. Telomeres, known as the "silky dividing clock" of cell life, are structures at the end of chromosomes consisting of small fragments of DNA and protein complexes that, together with telomere binding proteins, wear "hats" for chromosomes and represent the history and replication potential of cell replication.
    The breakthrough, published in
    , demonstrates that the cell aging regulatory mechanisms expressed by small molecules that regulate shear factors will lead scientists to develop new therapies that will help older people live healthier old lives while extending their lives and freeing them from chronic diseases as well as serious diseases such as stroke, heart disease and cancer.
