Fig. 4: Hindlimb unloading and X-ray radiation aggravate osteopenia development as evidenced by the bone morphology of distal femurs evaluated by micro-CT analysis.
From: The combined effects of simulated microgravity and X-ray radiation on MC3T3-E1 cells and rat femurs
a Rat body weights of four groups after 4 weeks (n = 6). b 3D micro-CT images within the distal femur of the four groups. c The three-dimensional architecture parameters of micro-CT analysis of four groups (n = 6). The data are expressed as the mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, ns not significant.
