All samples from the conventional ameloblastoma (CAM), mural unicystic ameloblastoma (MUA), luminal unicystic ameloblastoma (LUA), intraluminal unicystic ameloblastoma (IUA), and dental follicle (DF) groups showed expression of the proteins MT1-MMP, cortactin, Tks-4, and Tks-5 in neoplastic parenchymal cells as well as in the epithelium of the DF. This evidence concerns the gene SH3PXD2B and ameloblastoma.
