Recent advances in our understanding of the basic mechanisms that control liver regeneration and repair will produce the next generation of therapies for human liver disease. Insights gained from large-scale genetic analysis are producing a new framework within which to plan interventions. Identification of specific molecules that drive regeneration will increase the options for live-donor liver transplantation, and help treat patients with small-for-size syndrome or large tumors who would otherwise have inadequate residual mass after resection. In a complementary fashion, breakthroughs in the ability to manipulate various cell types to adopt the hepatocyte or cholangiocyte phenotype promise to revolutionize therapy for acute liver failure and metabolic liver disease. Finally, elucidating the complex interactions of liver cells with each other and various matrix components during the response to injury is essential for fabricating a liver replacement device. This focused review will discuss how a variety of important scientific advances are likely to impact the treatment of specific types of liver disease.
