Fig. 5From: Exosomes derived from human CD34+ stem cells transfected with miR-26a prevent glucocorticoid-induced osteonecrosis of the femoral head by promoting angiogenesis and osteogenesismiR-26a-CD34+-Exos play a bone tissue-protective role in a rat model of ONFH. a Three plane images including coronal section (COR), sagittal section (SAG), and transverse section (TRA) of the femoral head were reconstructed in the different groups. b Quantitative analysis of micro-CT results. Trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), bone volume per tissue volume (BV/TV), and trabecular number (Tb.N) were analyzed in the different groups. c HE staining of the femoral head in the different groups. Scale bar: 200 μm. d IHC images showing COL I staining of the femoral head in the different groups. Scale bar: 200 μm, *P < 0.05, **P < 0.01Back to article page
