عنوان انگلیسی Expression of Folliculogenesis-Related Genes in Vitrified Human Ovarian Tissue after Two Weeks of In Vitro Culture
چکیده انگلیسی مقاله Objective: This study was designed to evaluate the effects of vitrification and in vitro culture of human ovarian tissue on the expression of oocytic and follicular cell-related genes. Materials and methods: In this comparative study, ovarian tissue samples were obtained from eight transsexual women. Samples were cut into small fragments and were then assigned to vitrified and non-vitrified groups. In each group, some tissue fragments were divided into un-cultured and cultured (in α-MEM medium for 2 weeks) subgroups. The normality of follicles was assessed by morphological observation under a light microscope using hematoxylin and eosin (H&E) staining. Expression levels of factor in the germ line alpha (FIGLA), KIT ligand (KL), growth differentiation factor 9 (GDF-9) and follicle stimulating hormone receptor (FSHR) genes were quantified in both groups by real-time reverse transcriptase polymerase chain reaction (RT-PCR) at the beginning and the end of culture Results: The percentage of normal follicles was similar between non-cultured vitrified and non-vitrified groups (P>0.05), however, cultured tissues had significantly fewer normal follicles than non-cultured tissues in both vitrified and non-vitrified groups (P< 0.05). In both cultured groups the rate of primary and secondary follicles was significantly higher than non-cultured tissues (P< 0.05). The expression of all examined genes was not significantly altered in both non-cultured groups. Whiles, in both cultured tissues than non-cultured tissues, the expression of FIGLA gene was significantly decreased, KL gene was not changed, GDF-9 and FSHR genes was significantly increased (P< 0.05). Conclusion: Human ovarian vitrification following in vitro culture has no impairing effects on follicle normality and development and expression of related-genes. However, in vitro culture condition has deleterious effects on normality of follicles.
