    Metal ion-crosslinking multifunctional hydrogel microspheres with inflammatory immune regulation for cartilage regeneration by Zhuoming Xu, Zhuoming Xu, Jun Ma, Hanyin Hu, Hanyin Hu, Jintao Liu, Jintao Liu, Haiyang Yang, Haiyang Yang, Jiayi Chen, Hongwei Xu, Xinyu Wang, Huanhuan Luo, Gang Chen

    Published 2025-01-01
    “…Due to the complex pathogenesis of OA, multifaceted therapies that modulate inflammatory and immune microenvironmental disturbances while promoting cartilage regeneration are key to control the progression of OA.MethodsHerein, a multifunctional nanoparticle (DIC/Mg-PDA NPs) was constructed successfully by the metal chelation effect between Mg2+ and catecholamine bond from dopamine, followed by the amidation with diclofenac (DIC), which was then prepared into an injectable hydrogel microsphere (DIC/Mg-PDA@HM) with immune-regulating and cartilage-repairing abilities through microfluidic technology for the treatment of osteoarthritis.Results and discussionThe sustained release of Mg2+ from the composite hydrogel microspheres achieved inflammatory immune regulation by converting macrophages from M1 to M2 and promoted cartilage regeneration through the differentiation of BMSCs. …”
