Endometriosis is a chronic estrogen-dependent disorder and one of the most common causes of infertility in women. Resveratrol (RES) is a polyphenolic and phytoestrogenic compound with anti-oxidative, anti-inflammatory, anti-angiogenic, and anti-estrogenic properties. The aim of the present study was to investigate the effect of different concentrations of RES on human endometrial growth and angiogenesis in an in vitro three-dimensional (3D) model of endometriosis.Human endometrial tissues of endometriosis (endometriotic) and normal (endometrial) subjects (n = 9/groups) were biopsied in sterile conditions and cut into 1 × 2 mm pieces. Tissue fragments of each biopsy were given concentrations of 0 (control), 10, 50, 100 and 200 μM RES for 21 days in 3D culture condition using fibrin as an extracellular matrix. Scoring methods were used for tissue changes, including; cellular invasion, monolayer formation and angiogenesis. Nitric oxide (NO) was measured using Griess's reaction, and quantitative real-time polymerase chain reaction (qRT-PCR) was used to evaluate the apoptotic gene expression.The mean of growth scores of endometriotic and endometrial tissue showed a significant dose dependent inhibition (P < 0.05). The levels of NO also significantly decreased in different groups. Apoptotic genes (P53, Bax, Bcl2 and caspase 3) and Sirt1 showed a significant increase in various concentrations of RES in both tissues (P < 0.05).RES exert dose- and time-dependent inhibitory effects on human endometrial tissue, and its higher doses suggested it as a natural supplement to inhibit the growth and treatment of endometriosis.
