Figure 4: Photomicrographs of stained control tissue sections for solid multicystic ameloblastoma (odontogenic epithelium from dental follicle, a-d). (a) Odontogenic epithelium overlying a dense fibrous stroma (H and E, ×400). (b) Low SOX-2 focal nuclear staining of basal layer (IHC ×400). (c) Negative staining for OCT-4 (IHC ×400). (d) High membrane positivity for CD44 (IHC ×400). Photomicrographs of stained control tissue sections for ameloblastic carcinoma (oral squamous cell carcinoma, e-h). (e) Malignant epithelial island with anaplasia (H and E, ×400). (f) High nuclear staining for SOX-2 in tumor cells (IHC ×400). (g) High nuclear staining for OCT-4 in tumor cells (IHC ×400). (h) Intermediate membrane positivity for CD44 in tumor cells (IHC ×400)
