Antiserum to the 28-kilodalton vitamin D-dependent calcium-binding protein (CaBP) was used to localize CaBP in histologic sections of the continuously erupting incisor in mandibles obtained from normal rats. With the peroxidase--anti-peroxidase technique, no CaBP was detected in undifferentiated ameloblasts or in those which had become columnar and were facing pulp. Calcium-binding protein was first noted in the cytoplasm of random ameloblasts facing dentin in the presecretion zone. As the ameloblasts became more mature in the zone of enamel secretion, CaBP was uniformly present in their cytoplasm. Ameloblasts with Tome's processes clearly contained CaBP in these processes as well as in the cell-body cytoplasm. Near the later developmental stages of the zone of enamel secretion, some of the adjacent underlying cells of the stratum intermedium also contained CaBP in their cytoplasm. In some stratum intermedium cells and papillary cells, CaBP extended into the zone of enamel maturation, but not to the end of that zone. Cytoplasmic CaBP continued to be present in ameloblasts as they progressed through the zone of enamel maturation to the final, shortened cells at the gingival margin of the erupting incisor. No CaBP was detected in odontoblasts, pulpal cells, the stellate reticulum, or the outer dental epithelium.
