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

Peptide-functionalized materials show promise in controlling stem cell behavior by mimicking cell-matrix interactions. Supported lipid bilayers are an excellent platform for displaying peptides due to their ease of fabrication and low non-specific interactions with cells. In this paper, we report on the behavior of adult hippocampal neural stem cells (NSCs) on phospholipid bilayers functionalized with different RGD-containing peptides: either GGGNGEPRGDTYRAY ('bsp-RGD(15)') or GRGDSP. Fluid supported bilayers were prepared on glass surfaces by adsorption and fusion of small lipid vesicles incorporating synthetic peptide amphiphiles. NSCs adhered to bilayers with either GRGDSP or bsp-RGD(15) peptide. After 5 days in culture, NSCs formed neurosphere-like aggregates on GRGDSP bilayers, whereas on bsp-RGD(15) bilayers a large fraction of single adhered cells were observed, comparable to monolayer growth seen on laminin controls. NSCs retained their ability to differentiate into neurons and astrocytes on both peptide surfaces. This work illustrates the utility of supported bilayers in displaying peptide ligands and demonstrates that RGD peptides may be useful in synthetic culture systems for stem cells.
