SummaryFertility preservation is one of the most important issues in assisted reproductive technology. Previous studies have shown that cytokines and growth factors can improve follicle growth. The endometrial stromal cells secrete various factors that are involved in maintaining the integrity of uterine and epithelial secretory function. The platelet-rich plasma contains a large assembly of platelets suspended in plasma that successfully improves the viability and growth of various cell lines. This work aimed to investigate the influences of conditioned medium (CM) and platelet-rich plasma (PRP) on the development of ovarian follicles in infertile mice due to cyclophosphamide (CYC) exposure. In this study, 65 healthy BALB/c female mice (∼28–30 g and 6-8 weeks old) in five groups were studied. Immunohistochemistry (IHC) was used to detect growth differentiation factor 9 (GDF9)-positive cells. The mRNA expression levels of SMAD1, SMAD2, and BMP15 was assessed using reverse transcription-polymerase chain reaction (RT-PCR) method. The expression levels of SMAD1, GDF9, BMP15, and SMAD2 in the CM+PRP group was significantly more than in the CM and PRP groups. In addition, live birth occurred in the CM+PRP group. Treatment with CM+PRP in infertile mice due to Cy exposure increased fertility and live-birth rate. In general, our study suggested that the CM and PRP combination could improve the growth of mice ovarian follicles in vivo.

SummaryStable ovarian function is a key factor in the performance of the reproductive system. In contrast, some ovarian function-related diseases, such as polycystic ovarian syndrome, premature ovarian failure (POF), and ovarian cancer, are the main cause of infertility and death of women around the world. Despite multiple attempts, there are no effective tools against these conditions; however, mesenchymal stem cell-based therapy, especially using adipose tissue, has attracted much attention in medicine in light of its advantages such as easy isolation and accessibility. Conversely, it has been suggested that MSC-conditioned medium (CM) can restore injured tissues and has high immunocompatibility. So, here, we will summarize the effects of administration of MSCs and CM derived from adipose tissue on ovarian functions and related diseases.
