Oxygen-releasing scaffolds in tissue engineering: design strategies, fabrication and regenerative applications.
Review in Regenerative biomaterials, 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
Oxygen is indispensable for sustaining tissue and cell physiological functions, yet a hypoxic microenvironment often arises in tissue injury and regeneration, impairing graft scaffold performance and hindering repair processes. Thus, oxygen-releasing scaffolds have become a pivotal research frontier in tissue engineering. Via elaborate spatial constructions (e.g. electrospun fibers, hydrogels, microspheres) and diverse modification strategies, these scaffolds enable sustained, spatiotemporally controllable oxygen release at injury sites, alleviating local hypoxia and boosting tissue regeneration. They show great application potential in repairing skin, bone, nerve and cardiovascular tissues, as well as in tumor therapy, though comprehensive systematic summaries of their tissue engineering applications remain scarce. This review aims to delineate domain advances systematically: it first gives a holistic overview of core aspects, including oxygen carrier categories and delivery mechanisms, scaffold material modification and functionalization, intelligent responsiveness optimization and reactive oxygen species scavenging paradigms, then comprehensively recapitulates their application status and therapeutic efficacy across diverse scenarios (skin wound repair, bone defect regeneration, nerve injury remediation, tumor therapy, cardiovascular tissue reconstruction); finally, dissects practical application challenges and proposes future development trends, expecting to provide valuable references for in-depth research and clinical translation of oxygen-releasing materials in tissue repair and reconstruction.
