Radiographic and histological analysis of femoral specimens. a, b Radiographic imaging by X-ray was performed at 8, 14 and 20 weeks after the surgery, and rat femurs were harvested at 20 weeks after the surgery. c H&E, toluidine blue and safranin O-fast green staining of the femurs. d Quantification of fracture healing in calluses. e Bone nonunion rate of the control, CM-Exo and Exo groups. Abbreviations: 8w, 8 weeks; H&E, haematoxylin-eosin. **Statistically significant difference compared with the control group (P < 0.01). ##Statistically significant difference compared with the CM-Exo group (P < 0.01)
