TGFB1 and adenomyosis: Because adenomyosis is very prevalent and has rather an obscure pathophysiology with some evidence pointing to cell invasion abnormality, we propose a study to evaluate TGF-β1 expression in the ectopic endometrium of women with adenomyosis and to compare it with that in the endometrium of patients without this condition, considering the role played by TGF-β1 in cell proliferation and tissue remodeling.
