Figure 8.

bSEM images of a wild‐type and an Ambn ^lacZ/lacZ homozygous 7‐week mandibular incisor cross‐sections at 1 mm increments. Numbers in panels indicate distance in mm from apical loop. The higher the number the more advanced is the dentin and enamel development. Top: Lower magnifications views of wild‐type above the corresponding Ambn ^lacZ/lacZ homozygous mouse incremental sections. Note that dentin formation is comparable in the wild‐type and Ambn null mice, but that enamel formation is not. Below: Higher magnification bSEM images of sections 2 through 8 and details of boxed concretions
