The onset of wrinkles, muscle wasting and cataracts has been delayed and even eliminated in mice, say researchers in the US. It was done by “flushing out” retired cells that had stopped dividing. They accumulate naturally with age.
The scientists believe their findings could eventually “really have an impact” in the care of the elderly. Experts said the results were “fascinating”, but should be taken with a bit of caution.
The study, published in Nature, focused on what are known as “senescent cells”. They stop dividing into new cells and have an important role in preventing tumours from progressing. These cells are cleared out by the immune system, but their numbers build up with time. The researchers estimated that around 10% of cells are senescent in very old people.
Scientists at the Mayo Clinic, in the US, devised a way to kill all senescent cells in genetically engineered mice. The animals would age far more quickly than normal, and when they were given a drug, the senescent cells would die.

Science can never be compete with nature. You have to admit the nature philosophy. Ageing factors are very common and normal in every person. He has to accept the reality. But normally females try to overcome their ageing factor.
