Figure 4.  Micro-computed tomography (μCT) analysis of distal
femur showed similar trabecular bone parameters in 14-week-old
C57BL/6J and C57BL/6N mice. (A) Males and (B) females. (C)
Cortical bone parameters from midshaft femur of 14-week-old male
mice were also unchanged between the two strains. (D)
Measurement of serum osteocalcin and urinary deoxypyridinoline
(bone formation and bone resorption markers, respectively),
indicates that bone turnover was identical between 14-week-old
C57BL/6J and C57BL/6N. Abbreviations: BV/TV, bone volume/tissue
volume; TbN, trabecular number; TbSp, Trabecular spacing; Conn-
Dens, Connectivity density; SMI, structural model index (0 for
parallel plates, 3 for cylindrical rods); DA, degree of
anisotropy; CtPo, cortical porosity; CtTh, cortical thickness;
DPD, deoxypyridinoline; creat, creatinin.  Download authors'
