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

backgroundBone marrow stromal stem cells (BMSC) are appropriate source of multipotent stem cells that are ideally suited for use in various cell-based therapies. It can be differentiated into neuronal-like cells under appropriate conditions. This study examined the effectiveness of co-stimulation of creatine and retinoic acid in increasing the differentiation of BMSC into GABAergic neuron-like cells (GNLC).

methodsBMSC isolated from the femurs and tibias of adult rats were cultured in DMEM/F12 medium supplemented with 10% FBS, pre-induced using β-mercaptoethanol β-ME) and induced using retinoic acid (RA) and creatine. Immunostaining of neurofilament 200 kDa, neurofilament 160 kDa, nestin, fibronectin, Gamma-amino butyric acid (GABA) and glutamic acid decarboxylase (GAD) 65/67 were used to evaluate the transdifferentiation of BMSC into GNLC and to evaluate the effectiveness of pre-induction and induction assays. The expression of genes that encode fibronectin, octamer-binding transcription factor 4 (Oct-4), GAD 65/67 and the vesicular GABA transporter was examined in BMSC and GNLC by using RT-PCR assays during transdifferentiation of BMSC into GLNC.

resultsCo-stimulation with RA and creatine during the induction stage doubled the rates of GABAergic differentiation compared with induction using creatine alone, resulting in a 71.6% yield for GLNC. RT-PCR showed no expression of Oct-4 and fibronectin after the induction stage.

conclusionThe results of this study showed that the application of β-ME, RA, and creatine induced the transdifferentiation of BMSC into GLNC.
