Mature liver cells can revert back to stem cell-like state

Researchers at Harvard Stem Cell Institute have found that it is possible to force mature liver cells to revert back to a stem cell-like state.
This follows findings that cells in other organs can undergo the same change - adrenal glands, kidneys and lungs.

I think that this has incredible consequences for how we treat dis-ease...our attitude should be, how can we force the body to get to this state...where it heals itself.
What pathways can we alter with life changes of diet, exercise and state of mind??
