While the liver is one of the body's most resilient organs, it is still vulnerable to the ravages of stress and aging, leading to disease, severe scarring and failure. A research team now might have found a way to turn back time and restore the liver. In experiments using mice and liver tissue from humans, the researchers identified how the aging process prompts certain liver cells to die off. They were then able to reverse the process in the animals with an investigational drug.
