The loss of EfnB1 by osteoprogenitors influences osteoclast formation and function. (A–D) Representative methacrylate embedded sections of the distal femora from (A,B) sham and (C,D) ovariectomised (OVX) (A,C) Osx:Cre (Osx) control and (B,D) EfnB1OB−/− (EfnB1) mice 12 weeks post-surgery stained with TRAP. (E,F) Histomorphometric analysis quantitating (E) the number of TRAP+ osteoclasts lining the bone perimeter, and (F) the percentage of osteoclast surface to bone surface within the trabecular region of the distal femora of Osx:Cre and EfnB1OB−/− sham and OVX mice (n = 4–5 samples/strain/condition). (G) Circulating collagen type I was measured by ELISA (n = 5–8 samples/strain/condition). All statistical analysis performed by 2-way ANOVA, multiple comparisons, *p ≤ 0.05. Magnification A–D = 10 µM.
