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

Mesenchymal stem cells (MSCs) hold great promise for regenerative therapies and tissue engineering applications given their multipotential differentiation capacity. However, MSC isolation and expansion are typically performed on super-physiologically stiff tissue culture plastic (TCP), which may alter their behavior and lead to unintended consequences upon implantation. In contrast, electrospun nanofibrous scaffolds possess physical and mechanical properties that are similar to that of native tissue. In this study, we investigated whether isolation and expansion of juvenile bovine MSCs directly onto electrospun nanofibrous scaffolds better preserves MSC phenotype and stemness compared to TCP. Our data show that culture of MSCs on electrospun scaffolds reduces proliferation, decreases cellular senescence, and better maintains stemness compared to cells isolated and expanded on TCP, likely due to a reduction in cell contractility. Furthermore, in contrast to electrospun scaffolds, TCP biased MSCs towards a fibrotic phenotype that persisted even after the cells were reseeded onto a different substrate. Cells pre-cultured on electrospun scaffolds exhibited a heightened response to mechanical stimuli and greater chondrogenesis in methacrylated hyaluronic acid hydrogels. These data suggest that alternative substrates that better approximate the native cell environment should be used to preserve endogenous MSC behavior and may improve their success in tissue engineering applications. © 2017 Orthopaedic Research Society.
