Fig. 5From: Enhanced expression of the stemness-related factors OCT4, SOX15 and TWIST1 in ectopic endometrium of endometriosis patientsColocalization of OCT4 and SOX15 in human endometriotic tissue. Paraffin sections of human endometrium were processed for immunofluorescence microscopy. OCT4 (a), SOX15 (b), and DAPI (c) stainings are shown. OCT4/SOX15 merged picture (d) denotes colocalization in all epithelial cells whereas few stromal cells were only positive for OCT4 (white arrows)Back to article page
