Odaph Expression in Odaph+/+ Day 12 Mandibular Incisors. In the continuously growing mandibular incisor enamel formation progressively advances from basal (left) to incisal (right). (A) Sagittal section of a D12 mouse hemimandible. Boxes show the locations of the higher magnification views in (B) and (C). (B) Odaph expression was absent or trace in presecretory and secretory stage ameloblasts. (C) Late secretory, post-secretory transition (PST) and early maturation stages of amelogenesis. Boxes show the locations of the higher magnification views in (D) and (E) Odaph expression was low, but could be detected from the middle of box (D) to nearly the end of box (E). (D) On the left the ameloblasts were ending the secretory stage. Approximately midway through image (D), they entered post-secretory transition (PST) where the ameloblasts normally shorten while converting to ruffle-ended maturation stage ameloblasts. Note that Odaph expression is observed at the onset of PST. (E). Early maturation ameloblasts were positive for Odaph expression. No significant Odaph signal was detected in odontoblasts.
