| Biglycan and decorin are small leucine-rich proteoglycans that play several biological and structural roles in different tissues and organs. Several reports have indicated that biglycan participates in odontoblast and ameloblast differentiation and in the calcification process. In the present study we show that the expression of biglycan changes from within the ameloblasts and odontoblasts to the extracellular space according to the stage of animal development. In predentin and in the pulp space, however, biglycan was continually expressed throughout the period of investigation. In contrast, decorin was absent in odontoblasts and in ameloblasts and was exclusively expressed in predentin throughout the period of observation. In young rats, however, decorin... |

| During experiments in animal studies, it has been observed that enamelysin (MMP-20) is expressed during tooth development in the late secretory stage of amelogenesis but not in the mature enamel.The aim of this research was to determine the location of MMP-20 in human tooth germs in the different structures of the enamel organ.The detection of MMP-20 was performed by immunohistochemistry in 20 specimens obtained from human fetuses. Immunostaining of MMP-20 was observed from the presecretor stadium in stellate reticulum and intermediate stratum and in the basal portion of ameloblasts in the secretory stage in stellate reticulum, stratum intermedium, secretory ameloblasts, odontoblasts and dental papilla. The results of this research show the location of... |
