Modulation of phosphatase of regenerating liver-1 within placental mesenchymal stem cells instigates the transition between epithelial-to-mesenchymal transition and mesenchymal-to-epithelial transition subsequent to hepatic fibrosis

Open access

Abstract

Background/Aims: Epithelial-to-mesenchymal transition (EMT) plays a crucial role in hepatic fibrogenesis and liver repair in chronic liver disease. Our research highlights the antifibrotic potential of placenta-derived mesenchymal stem cells (PD-MSCs) and the role of phosphatase of regenerating liver-1 (PRL-1) in promoting liver regeneration.Methods: We evaluated the efficacy of PD-MSCs overexpressing PRL-1 (PD-MSCsPRL-1) in a bile duct ligationinduced rat injury model, focusing on their ability to regulate EMT.Results: PD-MSCsPRL-1 significantly reduced mesenchymal markers by downregulating TGFB1/SMAD2, outperforming naïve PD-MSCs. The transplantation of PD-MSCsPRL-1 enhanced BMP7/SMAD1/5 expression, promoting epithelial marker expression and stimulating BMP7 within hepatocytes, modulating downstream SMAD signaling. Importantly, further validation confirmed that PRL-1 directly interacts with BMP7 in hepatocytes.Conclusions: PRL-1 expression in PD-MSCsPRL-1 restores TGFB1/BMP7 balance, promoting hepatic regeneration through mesenchymal-to-epithelial transition. These findings highlight the therapeutic potential of engineered MSCs for liver disease and suggest innovative strategies for future stem cell therapies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
