Scientists have made a discovery in tackling the effects of ageing.
Experts from the University of Newcastle have identified the particular molecular pathway which causes cells to stop being able to divide.
Once cells stop dividing they lose their ability to support tissue regeneration and repair which gradually "leads to the physical signs of ageing, as more and more cells suffer the same fate".
However, now that this latest research, which was published in Molecular Systems Biology, has identified the exact molecular pathway involved in the process, scientists predict that modifying the ageing process could become "feasible".
Professor Thomas von Zglinicki, who led the research, said: "Now that we know the precise pathway that is involved, it becomes feasible to begin to think about how it can be modified to improve ageing without increasing the risk of cancer."
He highlighted that it was important to "tread carefully" because the same process which results in ageing also stops cells becoming cancerous.
