Yoda1‐Functionalized Nanozymes Coordinate Piezo1 Activation and Mitochondrial Protection to Reprogram the Diabetic Osteoimmune Micromilieu and Promote Vascularized Bone Repair

Advanced Science, EarlyView.
Diabetic bone defects remain a critical clinical challenge. A 3D‐printed BCPG‐MF@Y scaffold, embedding Yoda1‐functionalized manganese dioxide‐ferritin nanozymes, scavenges mtROS, suppresses the cGAS–STING pathway, and reverses cellular senescence, while Yoda1 activates Piezo1 to direct BMSCs fate to synergistically reprogram the osteoimmune ...
