Modulation of PRL-1 within placental MSCs instigates the transition between EMT and MET subsequent to hepatic fibrosis.
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 ligation (BDL)-induced 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 (MET). These findings highlight the therapeutic potential of engineered MSCs for liver disease and suggest innovative strategies for future stem cell therapies.
期刊介绍：
Clinical and Molecular Hepatology is an internationally recognized, peer-reviewed, open-access journal published quarterly in English. Its mission is to disseminate cutting-edge knowledge, trends, and insights into hepatobiliary diseases, fostering an inclusive academic platform for robust debate and discussion among clinical practitioners, translational researchers, and basic scientists. With a multidisciplinary approach, the journal strives to enhance public health, particularly in the resource-limited Asia-Pacific region, which faces significant challenges such as high prevalence of B viral infection and hepatocellular carcinoma. Furthermore, Clinical and Molecular Hepatology prioritizes epidemiological studies of hepatobiliary diseases across diverse regions including East Asia, North Asia, Southeast Asia, Central Asia, South Asia, Southwest Asia, Pacific, Africa, Central Europe, Eastern Europe, Central America, and South America.
The journal publishes a wide range of content, including original research papers, meta-analyses, letters to the editor, case reports, reviews, guidelines, editorials, and liver images and pathology, encompassing all facets of hepatology.
