Figure 6. Using traditional serial section for imaging of maxilla of Pdgfra^CreER×Nfatc1^DreER× LGRT mice (tracing 11 days).

(A) Using this procedure, a total of 117 slices were collected in this sample. (B) Representative images acquired by confocal microscopy (scale bar = 200 μm). Box 1: coronal pulp; Box 2: root pulp; Box 3: PDL (scale bar = 50 μm). (C) Maxilla M1 after 3D reconstruction by imaris, including pulp and PDL with virtual dentin shell (white) in buccal view (scale bar = 300 μm). (D) Image stack was displayed in buccal view, coronal view, and radicular view of pulp and PDL, respectively (scale bar = 300 μm).

Figure 6—figure supplement 1. The total 117 slices of maxilla M1 of Pdgfra^CreER×Nfatc1^DreER× LGRT mice sample (tracing).

The images were acquired by confocal microscope, ZsGreen⁺ cells in green, tdTomato⁺ cells in red, DAPI in blue.
