1 · What the graph read from 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.

2 · The registry

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

Serum used in culture medium brings risks of immune reactions or infections and thus may hinder using ex vivo expanded mesenchymal stem cells (MSCs) for medical treatment. Here, we cultured MSCs in a serum-free medium (SF-MSCs) and in a medium containing 10% fetal bovine serum (10%MSCs) and investigated their effects on inflammation and fibrosis. MSC-conditioned medium suppressed transforming growth factor-β1-induced phosphorylation of Smad2 in HK-2 cells, with no significant difference between the two MSCs. This finding suggests that the direct antifibrotic effect of SF-MSCs is similar to that of 10%MSCs. However, immunohistochemistry revealed that renal fibrosis induced by unilateral ureteral obstruction in rats was more significantly ameliorated by the administration of SF-MSCs than by that of 10%MSCs. Coculture of MSCs and monocytic THP-1 cell-derived macrophages using a Transwell system showed that SF-MSCs significantly induced polarization from the proinflammatory M1 to the immunosuppressive M2 phenotype macrophages, suggesting that SF-MSCs strongly suppress the persistence of inflammation. Furthermore, the gene expression of tumor necrosis factor-α-induced protein 6 (TSG-6), which inhibits the recruitment of inflammatory cells, was higher in SF-MSCs than in 10%MSCs, and TSG-6 knockdown in SF-MSCs attenuated the anti-inflammatory responses in unilateral ureteral obstruction rats. These findings imply that SF culture conditions can enhance the immunosuppressive and antifibrotic abilities of MSCs and the administration of ex vivo expanded SF-MSCs has the potential to be a useful therapy for preventing the progression of renal fibrosis.
