Mice deficient for β-catenin in osteoclast precursors are osteopenic. (A) Microcomputed tomography (µCT) analysis of the femurs of LysM-Cre+/+ β-catenin+/+ (β-cat+/+) and LysM-Cre+/+ β-cateninfl/fl (β-catΔ̃Δ mice. Upper photographs: longitudinal view; lower photographs: axial view of the metaphyseal region. The parameters are based on the µCT analysis of the metaphyseal region of mice at the age of 6 weeks. (B–D) Histological analysis of the tibiae. (B) Photographs represent TRAP and hematoxilin staining. (C) Osteoclastic and (D) osteoblastic parameters were obtained from bone morphometric analysis of mice at the age of 6 weeks. Graphs show mean ± SEM, N=5. *, P < 0.05; **, P < 0.01.
