Cell-mediated contraction of vitreous explants from chicken embryo: possibility of screening for therapeutic agents against proliferative vitreoretinal diseases.

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
purposeWe aimed to establish a novel screening system for identifying potential therapeutic agents for treating proliferative vitreoretinal diseases (PVDs). In this study, we focused on vitreous explants from chicken embryos and evaluated the usefulness of quantitatively analyzing the effects of potential candidates on cell-mediated vitreous contraction, which leads to blindness in PVDs.
methodsVitreous explants were extracted from 19-day-old embryonic chickens and then incubated with retinal Müller cells or endothelial cells to permit cell adhesion. After cell adhesion occurred, we examined the effect of the attached cells on the wet weight of vitreous explants as an index of vitreous contraction. We also performed hematoxylin and eosin staining to characterize the cell morphology on the vitreous surface.
resultsContraction of the vitreous explants was observed after cell adhesion of not only retinal Müller cells but also endothelial cells. We confirmed the adhesion of these cells on vitreous explants and estimated the number of adherent cells with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) analysis. The cells on the vitreous surface presented an elongated fibroblast-like phenotype. Integrin was found to be a receptor involved in cell adhesion on the vitreous surface. DISCUSSION: Our results suggest that vitreous explants from chicken embryos may be novel useful tools for screening antiadhesion therapeutic agents in PVDs. This preliminary study must be validated with human vitreous and human retinal pigment epithelial cells.
