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

backgroundThymidine analog 5-ethynyl-2-deoxyuridine (EdU) has recently been used for tracking mesenchymal stem cells (MSCs). In the present study, we tested whether EdU was cytotoxic and whether it interfered with differentiation, cytokine secretion and migration of MSCs.

methodsEdU labeling was performed by incubating adipose-derived stem cells (ADSCs) with 10(-8) mol/L of EdU for 48 h. Incorporation of EdU was detected by reaction with azide-conjugated Alexa594. The labeled and unlabeled ADSCs were compared for proliferation and apoptosis as determined by CellTiter and comet assays, respectively. They were also compared for neuron-like and endothelial differentiation as determined by morphology, marker expression and function. Comparison of their secreted cytokine profile was performed by cytokine antibody array. Comparison of their response to homing factor SDF-1 was performed by migration assay.

resultsEdU was incorporated into the nucleus in approximately 70% of ADSCs. No significant differences in proliferation and apoptosis rates were observed between EdU-labeled and unlabeled ADSCs. Isobutylmethylxanthine induced both EdU-labeled and unlabeled ADSCs to assume a neuron-like morphology and to express β-III tubulin. Endothelial growth medium-2 (EGM2) induced endothelial differentiation in both EdU-labeled and unlabeled ADSCs, including the ability to uptake low-density lipoprotein and to form capillary-like structures as well as the expression of vWF, eNOS and CD31. EdU-labeled and unlabeled ADSCs exhibited identical secreted cytokine profile and identical migratory response to SDF-1. DISCUSSION: At the recommended dosage of 10(-8) mol/L, EdU is non-toxic to ADSCs. EdU label did not interfere with differentiation, cytokine secretion or migratory response to SDF-1 by ADSCs.
