Objective: Human follicular fluid (FF) contains different cell populations including mesenchymal stem cells. Studies tried to improve their differentiation to oocyte and use them in infertility treatments. Using an antioxidant may improve the quality of these cells. The present study investigated the effects of different doses of melatonin on FF-derived cells grown to oocyte-like cells (OLC). Methods: Cell viability (MTT assay), flow cytometry, and ICC staining were utilized to evaluate CD105 and CD34 expression; colony forming unit assay (CFU-F) capability, qRT-PCR were used to investigate ZP1, ZP2, ZP3, GDF9, and SCP3 expression. AMH, Estradiol and Progesterone levels in the supernatant were measured. Morphological characteristics of fibroblast-like cells changing to a round shape were seen specifically in the group treated with melatonin 10-7M after 2 weeks. Results: There was no difference between control and treatment groups for MTT and CFU assays. ICC staining was positive for CD105 marker and negative for CD34 hematopoietic stem cell marker. qRT-PCR results indicated that ZP1, ZP2, GDF9, and SCP3 expression increased in the group treated with melatonin 10-7M in Week 2, while ZP3 decreased in this group. Progesterone and AMH were detected in differentiation medium. Conclusions: Melatonin may improve in vitro formation of OLCs.
