Liver disease is the 5th commonest cause of death in the UK and the deaths from cirrhosis are rapidly rising. Currently the only curative option for end-stage liver disease is liver transplantation. Donor organ availability cannot even meet current demand and many patients die whilst waiting for a suitable organ. Alternative therapeutic strategies are urgently required for the treatment of advanced liver disease.
The normal liver regenerates through division of mature hepatocytes. However, in chronic liver injury this capacity is lost. Fortunately we have a second tier of cells that can regenerate the liver- the Hepatic Progenitor Cells (HPCs or oval cells). These bipotential progenitor cells can give rise to both hepatocytes and biliary epithelium but may also be a potential source of liver cancer.

Approaches and progress
Our program of research concentrates on understanding how the Hepatic Progenitor Cells regenerate the liver in chronic disease and how this process becomes deranged in the development of liver cancer. By understanding what controls this process we aim to be able to promote healthy liver regeneration and reduce the formation of liver cirrhosis and cancer.
We are also developing pre-clinical and clinical tools to stimulate liver regeneration and reduce scarring using cell therapy. In particular we have found that bone marrow derived macrophages can promote liver regneration and reduce scarring and this is being developed as a clinical therapy (funded by the Medical Research Council). We have a clinical research program of “stem cell therapy for cirrhosis” funded by the Jules Thorn Trust and Scottish Enterprise.

In the healthy liver, the liver stem cells are only found surrounding the bile ducts close to the blood vessels (black area, on right with some red blood cells in orange).
