From: Expression Pattern of Stemness-Related Genes in Human Endometrial and Endometriotic Tissues
Representative IHC staining of OCT4 in human endometrium and in endometriotic tissue. Hematoxilin counterstaining. Endometriotic tissue (A, B) is compared with endometrial tissue (E, F). IHC staining of serial sections of the tissue used in A without antibody was done as a negative control of the reaction (C, D). Immunohistochemical staining of serial sections of the tissue used in E without antibody was done as a negative control of the reaction (H, G). Black arrows in B and F indicate representative OCT4 IHC-positive cells. Subparts (B, D, F, H) represent 100× magnification of the area enclosed in the black perimeter in A, C, E, G (40× magnification).
