Oligodendrocyte precursor cell transplantation attenuates inflammation after ischemic stroke in mice.
Article in Frontiers in neurology, 2025. 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
Background: Disruption of blood-brain barrier and neuroinflammation are critical pathological features in the acute phase of ischemic stroke. This study investigates whether oligodendrocyte precursor cell transplantation can downregulate inflammation to attenuate blood-brain barrier disruption following ischemic brain injury. Methods: Adult male Institute of Cancer Research mice ( Results: Oligodendrocyte precursor cell transplantation reduced infarct volume, alleviated anxiety and depression, and promoted neurological recovery after ischemic stroke. Compared to the control group, oligodendrocyte precursor cell treated mice exhibited reduced levels of inflammatory cytokines IL-1β, IL-6, and TNF-α, reduced neutrophil infiltration, and diminished loss of tight junction protein. Oligodendrocyte precursor cells alleviated inflammation by increasing β-catenin expression. The administration of β-catenin inhibitor blocked the beneficial effects of oligodendrocyte precursor cell transplantation on neuroinflammation and blood-brain barrier permeability. Conclusion: This study demonstrates that oligodendrocyte precursor cell transplantation attenuates neuroinflammation and protectes blood-brain barrier in the acute phase of ischemic stroke. Our findings indicate that oligodendrocyte precursor cell transplantation is a promising therapeutic approach for ischemic stroke.
