Emerging strategies for spinal cord injury repair: stem cells, extracellular vesicles, biomaterials, and neuromodulation.
Review in Frontiers in bioengineering and biotechnology, 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
Spinal cord injury (SCI) is a devastating condition that frequently results in permanent disability. Repair and functional recovery after SCI are hindered by the complexity of its pathophysiology and the inherent challenges of neural regeneration within the central nervous system. Despite decades of research aimed at elucidating its pathological mechanisms and developing effective strategies to promote axonal regeneration and circuit rewiring, successful therapeutic outcomes remain limited. Recent advances in bioactive materials and stem cell technology have shifted the research focus from solely stimulating corticospinal tract regeneration toward building intermediate neural networks to facilitate neural repair and circuit reconstruction. Concurrently, emerging technologies that modulate neural activity through physical modalities, such as electrical, magnetic, and ultrasonic stimulation, are rapidly evolving. Among these emerging strategies, several-including stem cell therapy, biomaterial-based interventions, and electromagnetic stimulation-have advanced to clinical trials, with some already entering clinical practice. This review summarizes the major contemporary strategies and research advances in SCI repair. It details the mechanisms and latest developments in stem cell and extracellular vesicle therapy, biomaterial applications, and neuromodulation techniques. Finally, it discusses future therapeutic directions and ongoing challenges in clinical translation.
