Abstract: Objective: To explore the feasibility of using the alizarin red/ alcian blue double staining to observe the whole development of mouse mandible. Methods: Alcian blue and alizarin red solution were used to double stain the E15.5, E16.5, E18.5 and P90 mouse mandibular skeleton. We observed the whole development of mandible, especially focused on the Meckel's cartilage and condylar cartilage. Results: The bone and cartilage could be stained as red or blue respectively. The morphology of the developmental mandible could be clearly observed under the stereo microscope. The Meckel's cartilage was not tightly connected to the surrounding tissues. The condylar cartilage was independent of the Meckel's cartilage, and was tightly connected to the mandibular periosteum. Conclusion: Using the alizarin red/alcian blue double staining could successfully observe the whole development process of mouse mandible. The Meckel's cartilage may not directly take part in the bone formation of mandible, and the condylar cartilage may originate from the mesenchymal cell in tail end of mandible.
