Efficacy of redox nanoparticles for improving survival of transplanted cells in a mouse model of ischemic stroke.
Article in Human cell, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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 success of cell transplantation therapy for ischemic stroke is hindered by the low cell survival rate in poststroke brain, due in part to high free radical production and ensuing oxidative stress. We have developed redox nanoparticles to eliminate reactive oxygen species. In this study, we tested the protective efficacy of these redox nanoparticles in cell culture and a mouse model of ischemic stroke. Induced human dental pulp stem cells were subjected to oxygen-glucose deprivation and reoxygenation to recapitulate ischemia and reperfusion in the penumbra surrounding a cerebral infarct. Cell viability using WST-8 assay, apoptosis using TUNEL, free radicals using MitoSOX, and inflammatory cytokines using ELISA kit were measured in the presence and absence of redox nanoparticles after oxygen-glucose deprivation and reoxygenation. The scavenging activity of redox nanoparticles against reactive oxygen species was detected by electron spin resonance. Moreover, induced cells were transplanted intracerebrally into to the distal middle cerebral artery occlusion model with and without redox nanoparticles, and the survival rate measured. Cell viability was enhanced, while apoptosis, free radical generation, and inflammatory cytokine expression levels were reduced in cultures with redox nanoparticles. Further, reduced redox nanoparticles were detected in the cytoplasm, indicating free radical scavenging. Addition of redox nanoparticles also improved the survival rate of transplanted cells after 6 weeks in vivo. These redox nanoparticles may increase the applicability and success of induced stem cell therapy for ischemic stroke patents by promoting long-term survival.
