Methods One-year-old male beagles were selected for surgical modeling after anesthesia. The tissues of the distraction osteogenesis area were taken respectively at the early, middle and late stages of distraction osteogenesis in beagles after euthanasia. After decalcification, the sections were stained by hematoxylin and eosin(HE) staining, Masson staining, methylene blue-acidic magenta staining, Von Kossa staining and modified alizarin red S staining, and modified safranin-O fast green staining, respectively, and the effects of staining were compared. Results HE staining could be used to observe the basic structure of the distraction osteogenesis area. The Masson staining showed sharp color contrast and clear structure, which could clearly distinguish collagen fibers from muscle fibers and mature bones from new bones. The modified safranin-O fast green staining and the methylene blue-acidic magenta staining were poorly differentiated at the early and middle stages of the distraction osteogenesis, but the two staining methods could clearly distinguished mature bones from new bones at the late stage of distraction osteogenesis. The Von Kossa staining and the modified alizarin red S staining were not very effective because the samples had been decalcified. Conclusion For the staining study of the distraction osteogenesis area, Masson staining has better staining effects at the early, middle and late stages of distraction osteogenesis. The modified safranin-O fast green staining and the methylene blue-acidic magenta staining are only suitable for the late stage of distraction osteogenesis. The Von Kossa staining method and the modified alizarin red S staining method are not suitable for the staining of tissue sections after decalcification. %R 10.3969/j.issn.1674-3806.2022.04.08 %U http://www.zglcxyxzz.com/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
