(A) Representative µCT reconstructions of femoral trabecular bone from 4-month-old WT and cKO mice that were either ovariectomised (OVX) or sham operated (sham), and treated with either vehicle (OVX+Veh), 20µg/kg risedronate (OVX+Ris), or 40µg/kg alendronate (OVX+Ale) for 4 weeks. (B) Trabecular bone volume (BV/TV); (C) Bone mineral content per tissue volume (BMC/TV); and (D) connectivity density determined at the end of the study by µCT in the different treatment groups (n=5). a, p< 0.05 vs WT; b, p< 0.05 vs Sham, 2-way ANOVA, and post-hoc multiple t-test (Holm-Sidak).
