Stem Cells in Post-Stroke Regenerative Therapy: Current Role of Wharton's Jelly Mesenchymal Stem Cells in the Orchestrum.
Review in Brain sciences, 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
BACKGROUND/
objectivesModern approaches for post-stroke rehabilitation cover mechanistically different ways-from physiotherapy to digital technologies. Among these approaches, stem cell-based therapy represents probably the most complex but promising strategy.
methodsWe discuss the current state-of-the-art of using mesenchymal stem cells (MSCs) in post-stroke regenerative therapy. Despite relatively wide use of bone marrow and adipose tissue MSCs, these cells represent a more mature ("adult") state, which limits their proliferative and regenerative potentials. Compared to the "adult" MSCs, less "mature" MSCs obtained from umbilical cord, specifically Wharton's jelly MSCs (WJ-MSCs), demonstrate unique functional capabilities and are free from certain technical and ethical issues.
resultsThe molecular and cellular mechanisms of action of WJ-MSCs are thoroughly discussed in comparison with abundantly used "adult" types of MSCs. We also comparatively evaluate their preclinical and clinical application for treating post-stroke patients. Recent findings indicate that not only MSCs but also their secretome/exosomes (cell-free product) represent a therapeutically beneficial cellular drug in post-stroke recovery. Specially designed and carefully evaluated protocols, which preserve the bioactivity of the cell-free product intact, are mentioned. Neuroprotective and neuroreparative properties of cell-free products-secretome and exosomes-derived from Wharton's jelly MSCs are summarized.
conclusionsCell-free products obtained from WJ-MSCs are an innovative adjunct therapy for post-stroke disorders, despite certain challenges and limitations of this type of therapy still present. By further investigation of the molecular composition and biological mechanisms of the WJ-MSC secretome and exosomes, their clinical applicability in neuroinflammatory and neurodegenerative pathologies will be promoted.
