Normally, hepatic progenitor cells (HPCs) are activated and differentiate into
hepatocytes or bile ductular cells to repair liver damage during liver injury.
However, it remains controversial whether the abnormal differentiation of HPCs
occurs under abnormal conditions. Lipopolysaccharide (LPS), a component of the
microenvironment, promotes liver fibrosis. In the present study, HPCs promoted
liver fibrosis in rats following carbon tetrachloride (CCl(4)) treatment.
Meanwhile, the LPS level in the portal vein was elevated and played a primary
role in the fate of HPCs. In vitro, LPS inhibited the hepatobiliary
differentiation of HPCs. Concurrently, HPCs co-cultured with LPS for 2 weeks
showed a tendency to differentiate into myofibroblasts (MFs). Thus, we conclude
that LPS promotes the aberrant differentiation of HPCs into MFs as a third type
of descendant. This study provides insight into a novel differentiation fate of
HPCs in their microenvironment, and could thus lead to the development of HPCs
for treatment methods in liver fibrosis.
