JAKARTA, kilat.com- Present a breakthrough to overcome agingscientists managed to safely rejuvenate tissue in middle-aged mice.
Researchers in the US have treated healthy animals with a form of gene therapy to refresh older cells. This has helped make the animals younger, according to the biological markers used to measure the effects aging.
While still far from being tested in humans, the findings could spark interest in new therapies, which appear to be able to slow or reverse the aging process. It can also be used as a means to treat age-related ailments, such as cancer, alzheimer’s, etc.
The findings of this study have been published in the journal ‘Nature Aging’.
The US scientists are referring to the previous findings of the Japanese Nobel laureate Prof. Shinya Yamanaka. He showed that a mixture of four molecules, known as Yamanaka factor, could regenerate mature cells into young stem cells capable of forming almost any tissue in the body.

The US team, led by Jasper and Prof Juan Carlos Izpisua Belmonte at the Salk Institute in California and the San Diego Altos Institute, found that mice, which received Yamanaka factor for several months would appear to resemble younger animals in many respects. The skin and kidneys, in particular, are showing signs of rejuvenation.(fig)
