Histomorphometric analysis of cortical bone parameters in femurs from 12-week-old female WT and Wnt16 KO mice. A, CSA. B, Marrow area (Ma.Ar). C, Periosteal BFR (Ps.BRF). D, Periosteal BFR/bone surface (Ps.BFR/BS). E, Periosteal MAR (Ps.MAR). F, Periosteal bone-forming surface (Ps.BFS). G, Periosteal TRAP (Ps.TRAP). Values are means ± SE. (n = 4–6). A, P < .05 vs WT mice.
