The distribution of proliferating cells during odontogenesis in the incisor teeth of Plecoglossus altivelis.
To examine the distribution of enameloid and proliferating cells during odontogenesis in the incisor teeth of Plecoglossus altivelis, we investigated the distribution of enameloid using alizarin red S and the distribution of bromodeoxyuridine (BrdU)-immunoreactive cells during odontogenesis of the teeth of the fish. Enameloid was present over the entire surface layer of the incisor teeth. BrdU-immunoreactive cells were observed in the inner and outer enamel epithelium, the odontoblasts, and dental papilla cells around the regions currently being formed. These findings suggest that ameloblasts and odontoblasts actively divide around the region currently being formed, suggesting that enameloid and dentin are made in cooperation by ameloblasts and odontoblasts.
