A microRNA delivery carrier for hepatic carcinoma therapy using layer-by-layer self-assembled mesenchymal stem cells.

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
backgroundSeveral microRNAs (miRNAs), such as miR101, have been reported to be effective for hepatocellular carcinoma (HCC) therapy in preclinical studies; while its further application is hampered due to the lack of desirable delivery systems. Based on the characteristics of mesenchymal stem cells (MSCs), including good biocompatibility and tropism to HCC, the current study was designed to investigate whether miR101-loaded MSCs (miR101-MSCs) using layer-by layer (LbL) self-assembled gelatin and alginate could target the delivery of miR101 to HCC.
methodsThe characterization of miR101-loaded MSCs was determined by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and Zeta potential analysis. The tropism and of miR101-MSCs to HCC were detected by Transwell chamber assay, and the anti-tumor potential of miR101-MSCs against HCC was examined by Annexin V-FITC/PI staining, BrdU incorporation assay, and immunoblotting with antibodies against proliferating cell nuclear antigen (PCNA) and caspase-3.
resultsThe results showed that a thin LbL film containing miR101 was encapsulated on the surface of MSCs. Furthermore, miR101-loaded MSCs had a tropism to hepatoma cells. Finally, treatment of BEL-7402 cells, an HCC cell line, with miR101-loaded MSCs led to significant proliferation inhibition and apoptosis of BEL-7402 cells.
