Fig. 1: Representative 3D µCT reconstructions of the trabecular compartment of the L4 vertebra.

a Saline + Earth; b TPO + Earth; c Saline + ; and d TPO + Flight. Tridimensional microstructural assessment of the vertebra evidencing increments in trabecular number in the TPO + Flight group as compared to the Saline+Flight group. TPO did not exhibit such osteogenic effects on Earth.
