Histomorphometric analysis of numbers of (a) osteoblasts (N.Ob/B.Pm) and (b) osteoclasts (N.Oc/B.Pm) at the bone perimeter per square millimetre from vertebrae L3 and L4. c Serum P1NP (ng/ml) (d) and serum CTX-1 (ng/ml) were determined by ELISA in WT and 11β-HSD1 KO mice receiving either vehicle or oral corticosterone (100 μg/ml). e Representative images of osteoblasts and f representative images of osteoclasts on trabecular bone surface. g The ratio of RANKL/OPG gene expression in the tibia from WT and 11β-HSD1 KO mice receiving either vehicle or oral corticosterone (100 μg/ml) was determined by quantitative RT-PCR. Values are expressed as mean ± standard error of six animals per group. Statistical significance was determined using two-way ANOVA with a Bonferroni correction. *p < 0.05, **p < 0.01, ***p < 0.001. Black arrows indicate osteoblasts and osteoclasts
