| Tooth enamel is the hardest tissue in the body. The organic matrix configuration is provided by the main proteins amelogenin, ameloblastin and enamelysin (MMP20), an enzyme that helps to shape the matrix. The aim of this study was to determine by histochemistry the expression of amelogenin and enamelysin through the rough endoplasmic reticulum in the late stages of amelogenesis, and its expression in the Complexus golgiensis (Golgi complex / Golgi apparatus) in the early stages in human fetuses. In early stages a colocalization of both proteins inside the Golgi apparatus was found, being more evident the relationship between Golgi and amelogenin (99.92 %). In the late stage, a colocalization of both proteins and rugged endoplasmic reticulum was found. With... |

| Amelogenin is one of the enamel matrix proteins secreted by ameloblasts during enamel formation in tooth development. Recent studies showed that the amelogenin is expressed in chondrocyte. Lysosome-associated membrane proteins (LAMPs) have been identified as binding partner proteins to amelogenin and it has been suggested they act as signaling receptors of amelogenin. The purpose of this study is to clarify the localization of amelogenin and LAMPs in growth plate cartilage and cartilaginous nodules in micromass culture. Mouse knee joints including tibia growth plate at 4 weeks old and micromass cultures of limb bud mesenchymal cells after 2 weeks were fixed in paraformaldehyde, routinely processed, sections were cut and immunostained with amelogenin,... |

| The amelogenin gene, AMEL, encodes an important protein for tooth enamel formation during development. It is highly conserved among mammals. The AMEL gene, which is located in sex chromosomes in humans, exhibits a length polymorphism for the X and Y copies of the gene. This length polymorphism has been reported in several mammal species, and the differences between the X and Y chromosomes are used for sex determination by amplifi cation of the polymorphic regions. In this work, we analyzed AMEL in Akodon azarae and Lagostomus maximus. In order to assess the identity of the individuals and verify the presence or absence of chromosomal rearrangements, a cytogenetic study was performed. To amplify the AMEL region, specifi c primers were designed using the... |
