Stress-strain response of wild type and oim/oim bone obtained from testing FIB-created micropillar samples under uniaxial compression loading. The curves represent the measurements taken up to the moment when peak force achieved after which strain bursts followed due to the abrupt failure of specimens, which, in turn, inhibited a smooth collection of load displacement data. Overall, wild type bones exhibited an appreciable amount of inelastic deformation prior to failure, whereas oim/oim bones largely failed in a brittle manner.
