摘要

骨缺损修复过程中常伴随血供不足与持续缺氧，导致细胞存活受限、血管生成受阻，并进一步抑制成骨过程。这已成为制约骨再生的重要因素。围绕这一关键瓶颈，以氧微环境调控为核心的载氧水凝胶体系逐渐成为骨组织工程领域的重要研究方向。该类体系依托水凝胶良好的生物相容性、可注射成形性及三维网络结构，通过整合过氧化物、全氟碳载氧体及酶/纳米酶等释氧模块，实现可控、可持续或微环境响应的氧气释放，并在一定程度上协同缓解氧化应激。该文系统综述了载氧水凝胶的基质材料选择、氧气来源与负载方式、释氧动力学调控策略，并从机制层面总结其在骨再生中的作用路径，包括改善局部缺氧、促进血管生成、增强成骨分化以及调节炎症反应与免疫微环境。该类体系在颅骨缺损及多种小动物骨缺损模型中可显著提高新骨形成质量与修复效率。综合现有研究证据，载氧水凝胶促进骨再生的关键不在于单纯提高氧供水平，而在于实现氧气释放强度、持续时间与骨修复阶段需求之间的精准匹配。未来研究需重点关注释氧动力学的定量调控、生物安全性及复杂病理微环境下的稳定性，以推动其向临床应用转化。

Abstract

Bone defect repair is often accompanied by inadequate vascularization and persistent hypoxia, which restrict cell survival, hinder angiogenesis, and ultimately impair osteogenesis, thereby posing a major challenge to effective bone regeneration. To overcome these limitations, hydrogel systems designed to modulate the local oxygen microenvironment have attracted increasing attention in bone tissue engineering. Owing to their favorable biocompatibility, injectability, and three-dimensional network architectures, these systems incorporate peroxide-based oxygen generators, perfluorocarbon oxygen carriers, and enzyme- or nanozyme-mediated oxygen-producing modules, enabling controlled, sustained, or microenvironment-responsive oxygen release while partially mitigating oxidative stress. This review summarizes recent advances in oxygen-releasing hydrogels, with an emphasis on hydrogel matrix selection, oxygen sources and loading strategies, and the regulation of oxygen release kinetics. The biological mechanisms underlying their pro-regenerative effects are further discussed, including the alleviation of local hypoxia, promotion of angiogenesis and osteogenic differentiation, and modulation of inflammatory responses and the immune microenvironment. Experimental evidence indicates that these hydrogel systems can substantially improve the quality of newly formed bone and enhance repair efficiency in calvarial and other small-animal bone defect models. Importantly, emerging studies suggest that successful bone regeneration depends not simply on increasing oxygen availability, but on achieving an appropriate balance among oxygen release intensity, duration, and the stage-specific requirements of bone repair. Future work should therefore prioritize quantitative control of oxygen release kinetics, long-term biosafety, and stability in complex pathological microenvironments to advance clinical translation.
