Fig. 2From: Serum exosomes from young rats improve the reduced osteogenic differentiation of BMSCs in aged rats with osteoporosis after fatigue loading in vivoComparison of the tibial microstructures and biomechanical parameters of rats in the loading and unloading groups. A Three-dimensional reconstruction of the bone microstructure. B Volume bone mineral density and tibial bone microstructure parameters: cortical thickness and total porosity percentage, Potot. C Biomechanical parameters: maximum bending strength, ultimate tibial load value (Fmax), stiffness constant K, and elastic modulus. The data are expressed as the mean ± SEM.
