Biomimetic KeMA hydrogel encapsulating CAP-EVs-MEF2C for inhibiting inflammation and senescence in intervertebral disc degeneration.
Article in Journal of nanobiotechnology, 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
This study aimed to develop a KeMA hydrogel encapsulating cartilage-affinity peptide (CAP)-modified extracellular vesicles (EVs) derived from MEF2C-overexpressing macrophages (KeMA@CAP-EVs-MEF2C) to modulate the MEF2C/P21/CDK2 axis, attenuating inflammation in cartilaginous endplate chondrocytes (CEPCs) and cellular senescence in nucleus pulposus cells (NPCs) to slow intervertebral disc degeneration (IVDD) progression. Single-cell RNA sequencing (scRNA-seq) identified MEF2C as a key regulator, upregulating p21 and suppressing CDK2 to reduce inflammation and cellular senescence. CAP-modified EVs within KeMA hydrogel demonstrated enhanced delivery and sustained-release properties. In vivo validation showed effective mitigation of cellular senescence and structural restoration in IVDD. This biomimetic system offers a promising strategy for IVDD treatment, emphasizing its targeting efficiency, biocompatibility, and sustained therapeutic benefits.
