Effects of 6-week and 12-week PEMF exposure on cancellous bone histology in the region of bone defect via Masson-Goldner trichrome staining.
(A) Representative histological images for bone microarchitecture in the region of bone defect by Masson-Goldner trichrome staining. The black areas represent titanium alloys and the red areas represent cancellous bones. Scale bar represents 100 μm for all images. (B) Quantitative comparisons of bone area fraction (bone area per total area) determined by the histological analyses between the Control and PEMF groups (n = 6). Values are all expressed as mean ± S.D. *Significant difference from the Control group at 6 weeks with P < 0.05. #Significant difference from the Control group at 12 weeks with P < 0.05.
