Woven Bone and Calcified Cartilage Outcomes at the Femur mid-shaft in Balb/C Mice.

<p>(A) Absolute WB.A was the same between age groups of each sex with males tending to be higher than females (ANOVA, p = 0.042). (B) However, when normalized by Ct.A, percent WB was significantly higher in the 6 week old mice than 13 week olds and there were no differences attributable to sex. (C) In contrast, the absolute amount of CC differed between ages and sex with older having twice that of younger and males having more than female. (D) When normalized by Ct.A it remained elevated in older animals but was not significant (ANOVA, p = 0.0581). (E) When normalized by WB.A, percent CC.A was significantly higher in 13week old mice than 6 week old mice.
