The liver provides vital metabolic, exocrine and endocrine functions in the body
as such pathological conditions of the liver lead to high morbidity and
mortality. The liver is highly regenerative and contains facultative stem cells
that become activated during injury to replicate to fully recover mass and
function. Canonical Wnt/?-catenin signaling plays an important role in regulating
the proliferation and differentiation of liver progenitor cells during liver
regeneration. However, possible roles of noncanonical Wnts in liver development
and regeneration remain undefined. We previously established a
reversibly-immortalized hepatic progenitor cell line (iHPx), which retains
hepatic differentiation potential. Here, we analyze the expression pattern of the
essential components of both canonical and noncanonical Wnt signaling pathways at
different postnatal stages of mouse liver tissues and iHPx cells. We find that
noncanonical Wnt4, Wnt5a, Wnt9b, Wnt10a and Wnt10b, are highly expressed
concordantly with the high levels of canonical Wnts in late stages of liver
tissues. Wnt5a, Wnt9b, Wnt10a and Wnt10b are able to antagonize Wnt3a-induced
?-catenin/TCF activity, reduce the stemness of iHPx cells, and promote hepatic
differentiation of liver progenitors. Stem cell implantation assay demonstrates
that Wnt5a, Wnt9b, Wnt10a and Wnt10b can inhibit cell proliferation and promote
hepatic differentiation of the iHPx progenitor cells. Our results strongly
suggest that noncanonical Wnts may play an important role in fine-tuning
Wnt/?-catenin functions during liver development and liver regeneration. Thus,
understanding regulatory mechanisms governing proliferation and differentiation
of liver progenitor cells may hold great promise to facilitate liver regeneration
and/or progenitor cell-based therapies for liver diseases.
