IkkβD, but not IkkαAA, mice are osteopetrotic. (A) Sections of the metaphyseal regions of the proximal tibia of 4-mo-old WT, IkkαAA, and IkkβΔ mice were subjected to H&E staining. (B) Decreased numbers of TRAP-positive (red-stained) multinucleated cells below the growth plate of IkkβΔ mice. TRAP-positive cells are marked by arrows. (C) Histomorphometric analysis of structural bone parameters in IkkβΔ (n = 6), IkkαAA(n = 6), and F/F (IkkβF/F, n = 6 ) mice at 4 and 7 mo of age. OcS/BS, osteoclast surface/bone surface; NOc/B.Pm, number of osteoclasts/bone perimeter/mm; Tr.Th, trabecular thickness (mm); Tr.N trabecular number/mm; Tr.S, trabecular separation/mm3; NOb/B.Pm, number of osteoblasts/bone perimeter/mm; ObS/BS, osteoblast surface/bone surface; MAR, mineral apposition rate. *P < 0.05.
