TSG-6 Activated MSC-derived Extracellular Vesicles Present Altered micro-RNA Contents and Ameliorate the Inflammatory Phenotype of Macrophages in Vitro.

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
Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) have shown promising immunomodulatory properties; however, strategies to enhance their therapeutic potential remain limited. Here, we employed CRISPR activation of the gene TSG-6 in MSCs to evaluate the impact of elevated TSG-6 on EV cargo and immunomodulatory function in an in vitro macrophage model. CRISPR-mediated gene activation was confirmed by RT-qPCR, demonstrating more than an 1800 fold increase in TSG-6 mRNA compared to controls. EVs were isolated from TSG-6 overexpressing MSCs and thoroughly characterized by nanoparticle tracking analysis, transmission electron microscopy, and Western blot, confirming their typical size distribution, morphology, and surface markers. Small RNA sequencing of these EVs revealed 15 differentially expressed miRNAs relative to EVs from control MSCs. When THP-1-derived macrophages were stimulated with LPS and treated with TSG-6-overexpressing MSC-EVs (Standard dosage: 1000 particle/cell, n = 11; Alternative dosages: 500, 1000, or 2000 particles/cell, n = 6), a marked reduction in pro-inflammatory cytokine gene expression (IL-1β, CCL2, CXCL10, and TNF-α) and secreted protein levels (CCL2, TNF-α, CXCL1, and MIP-3α) was observed. Taken together, these findings demonstrate that CRISPR-based TSG-6 activation reprograms MSC-EV miRNA cargo (as well as their protein cargo, as previously shown), which can boost their anti-inflammatory effects. These findings underscore the promise of CRISPR-activation as a novel platform for boosting the bioactive properties of MSC-EVs and enhancing immunotherapeutic efficacy.
