Enamel matrix proteins (EMPs)

Enamel matrix proteins (EMPs) are a complex mixture of proteins secreted by ameloblasts during the early stages of tooth development. While amelogenin constitutes the majority (approximately 90%) of this matrix, the term "Other enamel matrix proteins" refers to the remaining non-amelogenin components, including ameloblastin, enamelin, tuftelin, and amelotin. These proteins play a critical role in the biomineralization of enamel and the formation of the periodontal attachment apparatus, including cementum and the periodontal ligament. In a therapeutic context, these proteins are typically administered as a porcine-derived Enamel Matrix Derivative (EMD) to promote periodontal regeneration in patients with advanced gum disease. By mimicking the natural odontogenic environment, they stimulate cell signaling pathways that lead to the recruitment and differentiation of progenitor cells necessary for restoring lost periodontal tissues.
