Title: We might get younger if we use iPS cells technology. The research team of University of Tsukuba reported that iPS cells technology can reproduce cells which has already lost their ability of generating energy. It explodes the established theory and therefore so many people hope this kind of technology will be developed soon and could apply it to human beings. Though mitochondria inside the cells produces energy by using oxygen, when they get older, their ability will get decreased. Ones, It was considered that this kind of disability is caused by genetic mutation. if it were true, iPS cells couldn’t reproduce it. The research team investigated skin cells whose four younger people in group of between infant and 12 years old, and four elderly people in group of between 80 and 97 years old. Even extent of genetic mutation in both group were almost same and therefore an established theory was not correct. Then, the research team manipulated cells of elderly people to transform into iPS cells after that, transform to skin cells. These skin cells got recovered ability of generating energy.
