Inhibiting ferroptosis promotes the bone regeneration. A, B Representative micro-CT images (scale bar = 2 mm). C Micro-CT analysis results of BV/TV, Tb,N, and Tb,Th. in the control group (n = 6), OMVs group (n = 6) and OMVs + Fer-1 group (n = 6). D H&E staining showed that Fer-1 could promote the bone formation of extraction sockets, which was inhibited by OMVs (scale bar = 400 μm). E Collagen fiber deposition observed by Masson staining (scale bar = 400 μm)
