Figure 1From: Expression of RECK and matrix metalloproteinase-2 in ameloblastoma A representative immunohistochemical reactivity for RECK. (A) Keratocystic odontogenic tumor showing strong reactivity (× 400); (B) Follicular ameloblastoma showing strong reactivity in central polyhedral cells and weak in peripheral columnar cells (× 200); (C) Plexiform ameloblastoma showing reactivity in peripheral columnar cells and nearly no expression in central polyhedral cells (× 200); (D) Ameloblastic carcinoma showing no expression in tumor cells (× 400).Back to article page
