Wild-Type Scandinavian Planarian-Derived Extracellular Vesicles Accelerate Skin Wound Healing in Burn and Mechanical Injuries.
Article in ACS omega, 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
Skin wounds remain a clinical challenge, especially for burns and chronic wounds, and existing therapies seldom re-engage the rapid, scar-sparing repair programs observed in nature. Planarians are super-regenerators capable of rebuilding the entire organism from small fragments, and their extracellular vesicles might encode potent prorepair cues. But whether planarian-derived extracellular vesicles (EVs) can enhance mammalian skin healing is unknown. Therefore, we isolated EVs from a wild-type planarian flatworm collected in Sweden and evaluated their therapeutic activity in complementary wound models: a chicken chorioallantoic membrane assay and a human 3D skin model. In our models, planarian EVs significantly accelerated tissue regeneration and wound closure, and improved re-epithelialization and barrier integrity compared to controls. These data indicate that cross-species (xenogeneic) EVs from planarians carry bioactive factors capable of expediting cutaneous repair. Together, the results position planarian-derived EVs as a potential cell-free therapeutic strategy for burns and chronic wounds, motivating additional mechanistic and translational studies for clinical use.
