Bone remodeling is influenced by temperature. (A) Calcium and alizarin red double labeling were performed to determine the bone formation rate. (B, C) BFR/BS and MAR shown in A were calculated. (D) Representative TRAP staining of femur bone sections. (E) Histomorphometric quantification of Oc.N/BS in femur bone. (F–H) CTX-1, P1NP and IL-6 in the serum were detected by ELISA. Black arrows: TRAP positive cells. Data are shown as the mean ± SD (n=5 per group). Significance (p-value) was calculated using two-way ANOVA, *p < 0.05; 1 day (1 d), 14 days (14 d), 28 days (28 d), Normal: mice at room temperature (23°C), Cold: mice at 4°C.
