Recapturing the liver’s fountain of youth

The liver has been a model of tissue regeneration for decades, and it’s well known that a person’s liver cells can duplicate in response to injury. Even if three-quarters of the liver is surgically removed, duplication alone can return the organ to its normal functioning mass. It’s why people are able to donate part of their liver to someone in need—like this mother to her son who was born with biliary atresia.

But what about people with more chronic liver damage? Researchers led by Fernando Camargo, PhD, of the Harvard Stem Cell Institute and Boston Children’s Hospital’s Stem Cell Program, have new evidence in mice that it may be possible to repair such liver disease by forcing mature liver cells to turn back the clock and revert to a stem cell-like state, able to generate functional liver progenitor cells to replace damaged tissue.
