Abstract
Magnesium, an essential element in human physiology, is predominantly located in bone tissue. Since the early 20th century, magnesium-based biomaterials have demonstrated osteoinductive and angiogenic potential, positioning them as promising candidates for bone regeneration strategies. Hydrogels, composed of crosslinked hydrophilic polymers, provide a three-dimensional microenvironment mimicking the extracellular matrix (ECM), thereby supporting cell adhesion, nutrient diffusion, and controlled release of bioactive ions such as Mg²⁺. Recent advances in material science have enabled the design of multifunctional magnesium-loaded hydrogels that synergistically combine mechanical stability, immunomodulation, and spatiotemporal Mg²⁺ release to address critical-sized bone defects. This review systematically examines hydrogel classifications and elucidates magnesium-mediated biological signaling pathways that drive bone repair. A meta-analysis of 10 studies retrieved from PubMed, Web of Science, Scopus, and Embase was performed to assess the efficacy of magnesium-containing hydrogels in bone repair. The findings demonstrate that magnesium significantly enhances bone repair processes, underscoring its potential as a therapeutic agent for bone defect treatment.
期刊介绍:
The Journal of Materials Science: Materials in Medicine publishes refereed papers providing significant progress in the application of biomaterials and tissue engineering constructs as medical or dental implants, prostheses and devices. Coverage spans a wide range of topics from basic science to clinical applications, around the theme of materials in medicine and dentistry. The central element is the development of synthetic and natural materials used in orthopaedic, maxillofacial, cardiovascular, neurological, ophthalmic and dental applications. Special biomedical topics include biomaterial synthesis and characterisation, biocompatibility studies, nanomedicine, tissue engineering constructs and cell substrates, regenerative medicine, computer modelling and other advanced experimental methodologies.
