Anti-fibrotic Potential of WJ-MSC Exosomes in Liver Fibrosis: Mechanistic Insights and Dose-Response Efficacy.
Article in Iranian journal of pharmaceutical research : IJPR. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Hepatic fibrosis is a biological response characterized by the accumulation of extracellular matrix (ECM) during the wound healing process. Hepatic stellate cells (HSCs) play a pivotal role in fibrogenesis, transitioning from quiescent to myofibroblast cell types and leading to excessive ECM production. Platelet-derived growth factor (PDGF), a potent mitogen, is produced by activated HSCs, stimulating cell proliferation and migration. Objectives: This study aims to analyze the impact of Wharton's jelly mesenchymal stem cell (WJ-MSC)-derived exosomes on HSC activation induced by PDGF during liver fibrosis. Methods: Hepatic stellate cells-T6 cells were treated with PDGF-BB for 24 hours to induce activation, followed by treatment with varying concentrations of WJ-MSC-derived exosomes (0, 25, and 50 µg/mL) for another 24 hours. The effects of exosome treatment on HSC activation were evaluated through flow cytometry, differentiation assays, dynamic light scattering (DLS), transmission electron microscopy (TEM), RT-PCR, and western blot analysis. Results: Our study yields promising results, highlighting the potential therapeutic effects of WJ-MSC-derived exosomes on liver fibrosis. The dose-dependent decrease in fibrotic markers such as α-SMA, COLA1, and phosphorylated AKT protein in PDGF-BB-treated HSC-T6 cells suggests that WJ-MSC exosomes exert an anti-fibrotic effect by inhibiting HSC activation. Conclusions: These findings suggest that exosomes derived from WJ-MSCs hold therapeutic promise for liver fibrosis treatment by targeting key pathways involved in HSC activation and fibrogenesis. Further investigation into the underlying mechanisms of this anti-fibrotic effect and the potential clinical applications of WJ-MSC-derived exosomes in liver fibrosis management is warranted.
