Torsional testing of mouse femora with different immune phenotype. Keeping mouse under non-SPF conditions increased the torsional stiffness compared to 12 months old SPF mice. Yield torque and maximal torque increased by age and was further affected by non-SPF housing. The post-yield displacement (PYD) revelaed a more brittle fracture manner at 12 months under non-SPF compared to 12 months under SPF housing, the 3 month old bone fractured in a more ductile manner. N = 6 per group, boxplot distribution with median, Mann-Whitney U-test, *p < 0.05.
