CDH1 and adenomyosis: Several studies investigated the gene or protein (Western blot or immunohistochemical) expression of the target molecules in the ectopic and eutopic endometria of women with adenomyosis and in the endometria of patients without adenomyosis, including case-ectopic and case-eutopic tissue samples; case-ectopic and normal endometrium samples; or case-eutopic and normal endometrium samples (Figure 2 and Table 2).Fibrogenesis has been assessed through immunostaining with EMT markers (e.g., E-cadherin, Vimentin, TGF-β, Snail1, Slug, or Snail3), in vitro experiments, and mouse models.
