Soft surfaces induce neural differentiation via the neuron restrictive silencer factor.

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.
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
The physical and mechanical environment influence the differentiation and culture of stem cells. Early research in this field showed that mesenchymal stem cells (MSCs) adopt preferential lineages when cultured on surfaces of varying stiffness. Culture on very soft surfaces promoted neural differentiation. This effect has been observed in mesenchymal and embryonic stem cells and was shown to increase development of neural stem cells. However, providing further information on the molecular characterization of this phenomenon could help to guide the development of materials that enhance neural differentiation. Previously, our laboratory showed that chemical cues, forskolin and IBMX, induced neural differentiation of MSCs by downregulating the Neuron Restrictive Silencer Factor, leading to de-repression of neural gene expression. We sought to determine if the mechanism whereby soft surfaces induce neural differentiation could also involve NRSF function. We show that MSCs cultured on soft polydimethylsiloxane (PDMS) surfaces have reduced expression of NRSF as well as altered localization of NRSF. This suggests the modulation of transcription factors by surface substrate could be capitalized upon in designing materials for neural cell culture.
