Antioxidant and Anti-Senescence Polyvinyl Alcohol-Gallic Acid Supramolecular Hydrogels for Stem Cell Culture.
Article in Advanced healthcare materials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Replicative senescence presents a significant challenge in mesenchymal stem cell (MSC) expansion due to high reactive oxygen species (ROS) levels generated during culture. Elevated ROS levels lead to oxidative stress, cellular damage, and senescence, limiting the biomedical applications of MSCs. In this study, a supramolecular thermo-reversible hydrogel composed of the natural polyphenolic compound gallic acid (GA) and polyvinyl alcohol (PVA) was designed to scavenge ROS and mitigate MSC senescence. The PVA-GA hydrogel, stabilized by strong hydrogen bonding forces, exhibited an elastic modulus comparable to that of human soft tissue and facilitated the sustained release of GA over 14 days. It enhanced MSC survival, protected against oxidative stress, reduced intracellular ROS levels, diminished mitochondrial damage, and decreased cellular senescence. The hydrogel maintained the multilineage differentiation potential and typical phenotype of MSCs. Additionally, it preserved vascular endothelial growth factor (VEGF) secretion from MSCs under oxidative stress and enhanced their pro-angiogenic effect. The conditioned medium derived from MSCs in the hydrogel group promoted migration and tube formation of human umbilical vein endothelial cells (HUVECs). These findings suggest that the PVA-GA hydrogel holds significant promise for the biomedical applications of MSCs, potentially addressing the challenges posed by oxidative stress and cellular senescence.
