Abstract
The liver has a unique and extraordinary capacity for regeneration, even in adult organisms. This regenerative potential has traditionally been attributed to the replicative capabilities of mature hepatocytes and cholangiocytes, though emerging evidence suggests that other resident liver cell types such as progenitors, liver sinusoidal endothelial cells, and hepatic stellate cells respond to liver injury and contribute to repair. These other cells types are also associated with liver scarring, dysfunction, and carcinogenesis, which suggests that appropriate regulation of these cells is a major determinant of response to liver injury. The Reviews in this series explore possible contributions of liver progenitor cells, liver sinusoidal endothelial cells, and hepatic stellate cells to liver homeostasis and repair and highlight how these processes can go awry in chronic liver injury, fibrosis, and liver cancer.
