On day 56, the callus formation of the bone defects was observed by X-ray detection (A) and the bone microstructure indexes were measured by Micro-CT (B). *P < 0.05, **P < 0.01 vs. control group. Note: The control group refers to the model control group, which received the same amount of normal saline after establishing the rat bone defect model as the treatment group
