Structure-Inspired Lineage-Specific Matrix for Endogenous Neurogenesis in Spinal Cord Injury.

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) poses substantial challenges, often leading to permanent disability and requiring adequate neuronal regeneration for functional repair. Decellularized spinal cord (DSC) matrices hold promise due to their native 3-dimensional (3D) structure and extracellular matrix (ECM)-derived biochemical components. However, their limited mechanical properties and insufficient availability of growth factors hinder their effectiveness. To address these limitations, this study introduces a core-shell design that reinforces DSC with a hydrogel-based matrix capable of delivering essential growth factors while preserving its natural structure. By leveraging 3D printing and electrostatic adsorption, the engineered matrix retains the topological features of DSC while introducing new topographical and neurogenic cues. These instructive cues facilitated an 11-fold increase in the number of newly generated neuronal cells, demonstrating lineage-specific neuronal regeneration in vivo. Mechanistically, the synergistic effects of ECM-inspired structure and biochemical cues activated the ITGA2/ITGA11-ERK/AKT signaling axis and promoted M2 macrophage/microglia polarization, thereby reducing cavity and scar formation. This optimized microenvironment enhanced endogenous neurogenesis and supported functional recovery after SCI. Overall, this study developed a structure-inspired lineage-specific matrix that effectively stimulates endogenous neuronal regeneration, highlighting its potential for advancing spinal cord repair strategies.
