Abstract
The liver has a high regenerative capacity after acute liver injury, but this is often impaired during chronic liver injury. The existence of a dedicated liver stem cell population that acts as a source of regeneration during chronic liver injury has been controversial. Recent advances in transgenic models and cellular reprogramming have provided new insights into the plasticity of the liver epithelium and directions for the development of future therapies. This article will highlight recent findings about the cellular source of regeneration during liver injury and the advances in promoting liver regeneration.
Core tip: There have been controversies regarding the existence of a true liver stem cell population. Nevertheless, more evidence is beginning to reveal that cellular plasticity in the liver plays a role in liver regeneration. This mini-review highlights recent findings about plasticity in the liver epithelium.
