Bone regeneration of Ti ring implants with or without GO coating and BMP-2/SP loading in mouse calvarial defect model.

Notes: Histological analysis with Goldner’s trichrome staining of mouse calvarial defects with implants 8 weeks after treatment. (A) Lower magnification (×12.5) images of the implants. The black arrowheads and red arrows indicate the implant and newly formed bone, respectively. Scale bars =1 mm. (B) Higher magnification (×100) images of the implants. Scale bars =100 μm. (C) The area of new bone formation was determined using histomorphometric analysis (n=5). *P<05 between designated two groups.

Abbreviations: Ti, titanium; GO, graphene oxide; BMP-2, bone morphogenetic protein-2; SP, substance P.
