Secreted by ameloblasts, the enzymes MMP-20 (enamelisin) and KLK4 (kallikrein 4) play an important role in the enamel matrix degradation during amelogenesis. However, some benign and malignant neoplastic cells have shown the ability to produce them, what seems to increase the tumoral infiltrative and metastatic behavior. Thus, this paper proposes to study the immunoexpression of these enz…
