Anti-Apoptotic and Neurite-Protective Nanomedicine Augments Embryonic Stem Cells-Derived Retinal Ganglion Cell Transplantation in Glaucoma Recovery.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Retinal ganglion cell (RGC) degeneration represents a cardinal etiology of irreversible vision loss in glaucoma, where efficacious regenerative therapies remain scarce. RGC replacement therapy holds promise for visual function restoration, yet its therapeutic efficacy is constrained by the hostile glaucomatous microenvironment, dominated by oxidative stress that compromises transplanted RGC survival. Here, we report the design of multifunctional lithium-epigallocatechin gallate nanoparticles (Li-EGCG NPs) to synergistically enhance antioxidant capacity and neuroprotection. These NPs exhibit uniform spherical morphology, broad-spectrum reactive oxygen species scavenging activity, and exceptional biocompatibility with embryonic stem cell-derived RGCs (ESC-RGCs). In vitro, Li-EGCG NPs mitigate oxidative stress-induced apoptosis, preserve neurite integrity, and maintain mitochondrial homeostasis in ESC-RGCs. Transcriptomic analyses reveal activation of neuroprotective pathways, including apoptosis regulation, axon guidance, and mitochondrial function. In a retinal ischemia/reperfusion injury model, which serves as an acute pathological glaucomatous injury model, combinatorial Li-EGCG NPs and ESC-RGCs transplantation markedly improves ESC-RGCs survival, preserves retinal architecture, and restores visual function beyond single-modality therapy. This study establishes Li-EGCG NPs as a robust nanomedicine platform for retinal neurodegenerative diseases, offering a promising strategy to augment cell-based therapies.
