Both tuftelins and amelogenins have been associated with various functions during nucleation and maturation of the developing enamel matrix. In this study we conducted experiments to investigate whether tuftelins and portions of the amelogenin molecule were deposited and processed in spatially distinguished portions of the developing enamel matrix, using antibodies specific against tuftelin or amelogenins. The amelogenin antibodies were raised against recombinant and native amelogenins and also included an antibody against a polypeptide encoded by amelogenin exon 4. To compare spatial expression patterns of enamel protein epitopes, 3-day postnatal mouse molar tooth organs were processed for paraffin histology and cut into serial sections. Adjacent sections were exposed to antibodies against either tuftelin or various amelogenin epitopes. To investigate age-related changes of enamel protein expression, amelogenin and tuftelin antibodies were applied to tooth organs of developmental stages E19 and 1, 3, 5, 7, 9 and 11 postnatal days. Tuftelin was detected within the odontoblast processes during earlier stages of development (E19 and 1 day postnatal), whereas during later stages (3\u201311 days) it was recognized in a portion of the enamel layer adjacent to the dentine\u2013enamel junction. In contrast, all four antibodies against amelogenins reacted with parts of the ameloblast cytoplasm and the entire enamel layer. Using immunohistochemistry, we were not able to detect any differences in the spatial distribution of the four amelogenin epitopes investigated. The spatial differences in the distribution of amelogenin and tuftelin as observed in this study may be intepreted as an indication of functional differences between both proteins during early enamel biomineralization.<\/jats:p>","DOI":"10.1177\/002215549704500610","type":"journal-article","created":{"date-parts":[[2011,4,1]],"date-time":"2011-04-01T03:01:27Z","timestamp":1301626887000},"page":"859-866","source":"Crossref","is-referenced-by-count":42,"title":["Immunohistochemical
