From: Prognostic significance of Oct4 and Sox2 expression in hypopharyngeal squamous cell carcinoma
Expression of Oct4 and Sox2. Immunohistochemical staining for Oct4 and Sox2 expression in hypopharyngeal squamous cell carcinoma. Brown grains represent a positive signal (3, 3-diaminobenzidine staining). The positive expression site of Oct4 and Sox2 was mainly localized in the nucleus of tumor cells. (A) High Oct4 expression in tumor cells, (B) low Oct4 expression in tumor cells, (C) high Sox2 expression in tumor cells, and (D) low Sox2 expression in tumor cells.
