The present study had some advantages and limitations: As we mentioned earlier, it was the first study investigated the basal gene and protein expression and also the effect of resverstrol treatment on the gene and protein expression of VEGF, TGF-β and MMP-9 in ectopic (EESCs), and eutopic (EuESCs) endometrial stromal cells of women with endometriosis in comparison with non-endometriotic controls (CESCs). Here, TGFB1 is linked to endometriosis.
