Objective(s): Endometriosis is a complex gynecologic disease with unknown etiology. Noscapine has been introduced as a cancer cell suppressor. Endometriosis was considered as a cancer like disorder, The aim of present study was to investigate noscapine apoptotic effect on human endometriotic epithelial and stromal cells in vitro. Materials and Methods:In this in vitro study, endometrial biopsies from endometriosis patients (n=9) were prepared and digested by an enzymatic method (collagenase I, 2 mg/ml). Stromal and epithelial cells were separated by sequential filtration through a cell strainer and ficoll layering. The cells of each sample were divided into five groups: control (0), 10, 25, 50 and 100 micromole/liter (µM) concentration of noscapine and were cultured for three different periods of times; 24, 48 and 72 hr. Cell viability was assessed by colorimetric assay. Nitric oxide (NO) concentration was measured by Griess reagent. Cell death was analyzed by Acridine Orange (AO)–Ethidium Bromide (EB) double staining and Terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) assay. Data were analyzed by one-way ANOVA. Results: Viability of endometrial epithelial and stromal cells significantly decreased in 10, 25, 50 and 100 µM noscapine concentration in 24, 48, 72 hr (P
