Steatotic liver: a suitable source for the isolation of hepatic progenitor cells.

2011

Background: Alternative and/or complementary sources of cells such as hepatic progenitor cells (HPC) are under investigation for hepatic cell therapy purposes. Steatotic livers are those most commonly rejected for clinical transplantation and are also unsuitable for good quality hepatocyte isolation. Aim: Taken together these two facts, our aim was to investigate whether they could represent a suitable source for the isolation of progenitor cells. Methods: Rats fed for 7 weeks with methionine–choline deficient diets showing proved steatotic signs (i.e. increase in hepatic lipids; macrovesicular steatosis) and steatotic and normal human liver samples were used to study the expression of HPC …
