Fig. 2From: Enhanced expression of the stemness-related factors OCT4, SOX15 and TWIST1 in ectopic endometrium of endometriosis patientsExpression analyses in 49 paired cases with endometriosis. 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. All p-values of paired comparisons were analysed by paired t-testBack to article page
