IL-6 expression in the OVX mice during fracture healing. a, b Immunohistochemistry staining and quantifications of IL-6 in the fracture haematoma/callus of sham and OVX mice at different time points of fracture healing. DPF, days post-fracture. Scale bars, 200 μm. c mRNA expressions of IL-6 in the fracture haematoma/callus at different time points were determined by real time PCR. *, p < 0.05; **, p < 0.01 compared with the sham group. n = 6/group
