Abstract Bone organoids, in vitro models mimicking native bone structure and function, rely on 3D stem cell culture for self‐organization, differentiation, ECM secretion, biomineralization, ultimately forming mineralized collagen hierarchies. However, their development is often limited by the lack of suitable matrices with optimal mechanical properties sustained growth differentiation. To address this, a dynamic DNA/Gelatin methacryloyl (GelMA) hydrogel (CGDE) developed to recapitulate key biochemical features ECM, providing supportive microenvironment organoid formation. This dual‐network engineered through hydrogen bonding between DNA GelMA, combined GelMA network crosslinking, resulting appropriate strength enhanced viscoelasticity. During 21‐day culture, CGDE facilitates cellular migration promoting woven (WBO) formation via intramembranous ossification. These WBOs exhibit spatiotemporal architectures supporting mineralization tissue remodeling. In vivo studies demonstrate that CGDE‐derived self‐adaptive properties, enabling rapid osseointegration within 4 weeks. work highlights as robust scalable platform development, offering new insights into biology innovative strategies regeneration.

Non-alcoholic fatty liver disease (NAFLD), now recognized as metabolic dysfunction-associated steatotic (MASLD), represents a significant and escalating global health challenge. Its prevalence is intricately linked to obesity, insulin resistance, other components of the syndrome. As our comprehension MASLD deepens, it has become evident that this condition extends beyond liver, embodying complex, multi-systemic with hepatic manifestations mirror broader landscape. This comprehensive review delves into critical interplay between gut-liver axis oxidative stress, elucidating their pivotal roles in etiology progression MASLD. Our analysis reveals several key findings: (1) Bile acid dysregulation can trigger stress through enhanced ROS production hepatocytes Kupffer cells, leading mitochondrial dysfunction lipid peroxidation; (2) Gut microbiota dysbiosis disrupts intestinal barrier function, allowing increased translocation endotoxins like LPS, which activate inflammatory pathways TLR4 signaling promote via NADPH oxidase activation; (3) The redox-sensitive transcription factors NF-κB Nrf2 serve crucial mediators axis, regulating responses orchestrating antioxidant defenses; (4) Oxidative stress-induced damage function creates destructive feedback loop, further exacerbating inflammation progression. These findings highlight complex interrelationship pathogenesis, suggesting potential therapeutic targets for management.
