Aging of mice reversed in the lab

University of California researchers have managed to rejuvenate some rat cells, according to a study published in the journal Cell Reports. The team infused stem cells into the blood of old mice with a longevity gene, increasing the cell's potential for recovery.

The study also found that sirtuin-class protein SIRT3 plays an important role in helping blood stem cells to fight stress. "Our study is the first to show that sirtuins can reverse aging-related degeneration, " said Danica Chen, the study's lead researcher.

The experiment opens new avenues for the development of treatments for age-related degenerative diseases. "A gene mutation can lead to a longer life span, " the researcher adds. The expectation of scholars now is to understand the aging process to a sufficient degree so that it is possible to develop a "molecular source of youth."
