Abstract

One of the most intricate infertility problems among women is the number and quality of the oocytes. Menstrual blood-derived stem cells (MenSCs) are a recently discovered source of mesenchymal stem cells which is known as a suitable source of cells for regenerative medicine. We aimed to investigate whether MenSCs as autologous cell source from endometriosis, PCOS, and healthy women have different characteristics regarding their morphology, CD marker expression pattern, differentiation potential into oocyte-like cells, and oocyte-related genes expression. Menstrual blood samples (1-2 ml) from healthy and infertile women (PCOS and endometriosis) in the age range of 22-35 years were collected. Isolated MenSCs by the Ficoll-Paque density-gradient centrifugation method was characterized by flow cytometry. MenSCs were induced under 20 % follicular fluid (FF), and then they were evaluated for differentiation by Real time-PCR and immunocytochemistry assay. MenSCs derived from endometriosis women had different morphology from PCOS and healthy women, but similar regarding their CD marker pattern. All induced MenSCs showed morphological changes and expressed oocyte related genes (STELLA, GDF9, STRA8, PRDM, LHR, FSHR, SCP3, DDX4, and ZP2) in the 2nd week of culture, but there was a significant difference between the groups. Endometriosis-derived MenSCs showed higher levels of both gene and protein expressions. These findings propose that MenSCs derived from endometriosis and PCOS patients under 20 % FF, not only could differentiate into oocyte-like cells, but also showed more differential potential in comparison with healthy women. This indicates the possibility of using the patients' own MenSCs to differentiate into the oocyte-like cells.
