Bone marrow mesenchymal stem cells alleviate liver fibrosis after rat liver transplantation through JAK1/STAT5 pathway.
Article in Stem cell research & therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe effectiveness of bone marrow mesenchymal stem cells (BMSCs) in post-transplantation liver fibrosis has not been studied. The aim of this study was to investigate the effect of BMSCs on liver fibrosis and their role in the Janus-activated kinase (JAK) 1/ signal transducer and activator of transcription (STAT) 5 pathway after liver transplantation (LT).
methodsA rat model of post-LT liver fibrosis induced by cold ischemia injury was successfully established. BMSCs were injected into the rats through the portal vein. Hepatic stellate cell (HSC)-T6 were co-cultured with BMSCs in vitro after hypoxia-reoxygenation. JAK1 inhibitor Abrocitinib and JAK1 agonist RO8191 were used to study the JAK1/STAT5 signaling pathway.
resultsBMSCs significantly alleviated liver fibrosis caused by cold ischemia-reperfusion injury after rat LT in vivo. After BMSCs transplantation, the levels of JAK1 and p-STAT5 in rat liver were significantly reduced. After using Abrocitinib, the stage of liver fibrosis and the levels of collagen type I alpha 1 chain (COL1A1) and actin alpha 2 (ACTA2) decreased. After using RO8191, the stage of liver fibrosis and the levels of COL1A1 and ACTA2 increased. BMSCs significantly reduced the activation of HSC-T6 after hypoxia-reoxygenation in vitro. After co-culturing with BMSCs after HSC-T6 hypoxia-reoxygenation, the levels of JAK1 and p-STAT5 were significantly reduced. After the addition of Abrocitinib, the levels of COL1A1 and ACTA2 decreased in HSC-T6; in contrast, after adding RO8191, the levels of COL1A1 and ACTA2 increased in HSC-T6 after hypoxia-reoxygenation. After using anti-IL7 antibody or anti-IL7Rα in vivo and in vitro, the stage of liver fibrosis and the levels of COL1A1 and ACTA2 decreased as well as the phosphorylation level of STAT5.
conclusionsBMSCs alleviate hepatic cell damage, reduce hepatic cell-derived IL7, downregulate IL7R/JAK1/STAT5 in HSCs, thereby reducing HSCs' activation and ultimately alleviating liver fibrosis after liver transplantation.
