Ion‐Driven Regulation of Ca2 + Flow by Ti/Zn Composite Activates ERK/MAPK Signaling and Maintains Mitochondrial Homeostasis to Promote Macrophage‐Mediated Bone Regeneration
ABSTRACT The field of tissue engineering is transitioning from bioinert to bioactive materials that actively regulate host biology. Here, we developed a 3D‐printed porous Ti scaffold infiltrated with molten Zn to form an interpenetrating Ti/Zn composite with immunomodulatory and osteogenic bioactivity. Corrosion charac...
