Evaluation of apoptosis-related genes showed that E-MenSCs significantly decreased mRNA expression of BAX (proapoptotic gene) (0.052 fold, P = 0.05) and significantly increase mRNA expression of BCL-2 (antiapoptotic gene) (1.60 fold, P = 0.01) in endometriosis cells, as compared with NE-MenSCs (Figure 3). This evidence concerns the gene BCL2 and endometriosis.
