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

backgroundInterleukin-6 (IL-6) with IL-6 receptor (IL-6R) play an important role in the tissue regeneration in vivo, especially bone metabolism. Bone marrow -derived mesenchymal stem cells (BM-MSCs) are multipotent stromal cells, which are main origin of osteoblasts. However, the roles of IL-6 and IL-6R in the osteogenic differentiation of BM-MSCs are still unclear.

methodsThe expression of IL-6 and IL-6R was detected in BM-MSCs during osteogenic differentiation. The activation of the STAT3 pathway was assessed and its role in the osteogenic differentiation of BM-MSCs was determined using the specific inhibitor AG490. Exogenous IL-6/soluble IL-6R or antibodies against IL-6/IL-6R were used to confirm the mechanism by which the IL-6/IL-6R complex promotes the osteogenic differentiation.

resultsThe levels of IL-6 and IL-6R, especially the level of membranous IL-6R but not that of soluble IL-6R, increased during osteogenic differentiation in BM-MSCs. The levels of IL-6 and IL-6R were positively correlated with the osteogenic potential of BM-MSCs. The STAT3 signaling pathway was activated during the osteogenic differentiation of BM-MSCs. AG490 markedly inhibited the activation of the STAT3 pathway and, subsequently, the osteogenic differentiation potential of BM-MSCs. Additionally, exogenous IL-6 and soluble IL-6R accelerated the osteogenic differentiation of BM-MSCs. In contrast, antibodies against IL-6 or IL-6R suppressed the osteogenic differentiation of BM-MSCs. Moreover, IL-6 and IL-6R were found to stimulate each other's expression in BM-MSCs.

conclusionsIL-6 and IL-6R levels increase during the osteogenic differentiation of BM-MSCs. These two molecules form a complex to activate the downstream STAT3 signaling pathway, which promotes osteogenic differentiation in BM-MSCs via an autocrine/paracrine feedback loop.
