Fig. 3From: Enhanced expression of the stemness-related factors OCT4, SOX15 and TWIST1 in ectopic endometrium of endometriosis patientsExpression analyses in 50 control patients, and 110 patients with endometriosis (eutopic and ectopic). IHC was used to analyze the protein expression of OCT4 (a), SOX15 (b), TWIST1 (c) and DCAMLK1 (d). Results are expressed as mean score of the immunohistochemical staining ± SD. Epithelial and stromal expression was analyzed separately. Comparisons with the control group were analysed by t-test, comparisons between EP endometrium and endometriotic tissue were performed using Fisher combination testBack to article page
