Journal Article
The Potential Hepatocyte Differentiation Targets and MSC Proliferation by FH1
2025
Overview
The main cause of acute liver failure (ALF) is hepatocellular necrosis, which induces liver repair dysfunction and leads to high mortality. In recent years, studies have increasingly shown that stem cell‐derived hepatocyte‐like cells (HLCs) can be used for treatment in animal models of ALF. Notably, a hepatocyte differentiation strategy based on the small‐molecule compound functional hit 1 (FH1) successfully replaces HGF to promote the maturation of HLCs, but the underlying mechanism is still unclear. In this study, we used network pharmacology analysis to clarify the important role of the HGF/c‐Met signalling pathway in FH1‐induced hepatocyte (FH1‐iHeps) differentiation. After FH1 was added to mesenchymal stem/stromal cells (MSCs), proliferation and cell cycle progression were rescued by treatment with a tyrosine kinase (c‐Met) inhibitor. Additionally, c‐Met signalling in MSCs was significantly increased by treatment with FH1, as shown by the increased c‐Met, p‐p38, p‐AKT and p‐ERK1/2 protein levels. FH1‐iHeps efficiently improved the liver function of mice with acute liver injury and prolonged their lifespan. These data provide new insight into the mechanisms regulating the stemness properties of human umbilical cord‐derived stem cells (hUC‐MSCs) and reveal a previously unrecognised link between FH1 and c‐Met in directing hepatocyte differentiation.
