Mesenchymal stem cell origin contributes to the antitumor effect of oncolytic virus carriers.

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
Oncolytic virotherapy shows promise as a cancer treatment approach; however, its systemic application is hindered by antibody neutralization. This issue can be overcome by using mesenchymal stem cells (MSCs) as carrier cells for oncolytic viruses (OVs). However, it remains elusive whether MSC source influences the antitumor effect. Here, we demonstrate that their source affects the migration ability and oncolytic activity of OV-loaded MSCs. Among human MSCs derived from different tissues, bone marrow-derived MSCs (BMMSCs) showed a high migration ability toward cancer cells in two- and three-dimensional MSC-cancer cell co-culture models. Comprehensive gene expression and Gene Ontology-based functional analyses suggested that genes involved in cell migration and cytokine response influence the cancer-specific tropism of BMMSCs. Furthermore, MSC origin affected the susceptibility to OVs, including cytotoxicity resistance and OV release from MSCs. MSC-mediated OV delivery significantly increased the viral spread and antitumor activity compared with delivery by OVs alone, and OV-loaded BMMSCs demonstrated the most potent antitumor effect among OV-loaded MSCs. Our results offer promising insights into cancer gene therapy with carrier cells and can help with the selection of an appropriate MSC source for MSC-based OV therapy.
