Partial hepatectomy (PH), an established model for liver regeneration, reactivates transforming growth factor‐β (TGF‐β) signaling. Hepatic stellate cells (HSCs) are primarily responding cells for TGF‐β and resident in stem cell niche. In the current study, PH mice were treated with SB‐431542, an inhibitor of TGF‐β Type I receptor, aiming to address the role of TGF‐β signaling on the fate determination of HSCs during liver regeneration. After PH, control mice exhibited HSCs activation, progenitor cells accumulation, and a fraction of HSCs acquired the phenotype of hepatocyte or cholangiocyte. Blocking TGF‐β signaling delayed proliferation, impaired progenitor response, and scarring repair. In SB‐431542 group, merely no HSCs were found coexpressed progenitor makers, such as SOX9 and AFP. Inhibition of TGF‐β pathway disturbed the epithelial‐mesenchymal transitions and diminished the nuclear accumulation of β‐catenin as well as the expression of cytochrome P450 2E1 in HSC during liver regeneration. We identify a key role of TGF‐β signaling on promoting HSC transition, which subsequently becomes progenitor for generating liver epithelial cells after PH. This process might interact with an acknowledged stem cell function signaling, Wnt/β‐catenin.</jats:p> Transforming growth factor‐β signaling confers hepatic stellate cells progenitor features after partial hepatectomy Journal of Cellular Physiology |
