growth/size/body
• both males and females were significantly heavier at 9 weeks of age, but this difference was no longer apparent at 15 weeks of age
|
skeleton
• femurs show increased periosteal and endocortical diameters and greater moments of inertia in 9 and 15 week old males and in 9 week old females, with these differences no longer detected in older mice
• increased cortical area in 9 week old males
• femurs show increased bending strength and failure loads at 9, but not 15, weeks of age
|
• femoral heads ossify earlier than in wild-type, as evidenced by a trabecular bone pattern at 9 and 15 weeks of age that was not observed in wild-type at this age
