Proliferation tracing reveals regional hepatocyte generation in liver homeostasis and repair

Abstract excerpt

Zoning in on liver growth For organ homeostasis or regrowth after injury or disease, one or more stem cell populations is needed to rebuild lost tissue. There is considerable debate about the source of new cells in the liver. Two groups now identify the source of new hepatocytes (see the Perspective by Andersson).
