N normal phenotype
skeleton
• the number of osteoclasts is increased along the diaphyseal endocortical surface
• however, number of osteoclasts is normal in trabecular bone
• in 8 day growing mice, the number of osteoclasts along the endosteum is increased
• width of bones at the midshaft is increased
• thin cortical bone in femora and tibiae in 2 week old mice
• thin cortical bone in the calvaria
• treatment with a sclerostin-neutralizing antibody increases cortical bone thickness
• decrease in cortical bone formation
• rates of periosteal and endocortical mineral apposition are equally reduced
• increase in bone-formation rates
• failure of bone remodeling during growth
• increase in endocortical bone resorption
• reduction in mechanical strength measured at the diaphysis

hematopoietic system
• the number of osteoclasts is increased along the diaphyseal endocortical surface
• however, number of osteoclasts is normal in trabecular bone
• in 8 day growing mice, the number of osteoclasts along the endosteum is increased

immune system
• the number of osteoclasts is increased along the diaphyseal endocortical surface
