en Effect of Human Ovarian Tissue Vitrification/Warming on the Expression of Genes Related to Folliculogenesis Related Fields Related Fields مقاله کامل Full Length/Original Article <p>Background: Ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. This study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (FIGLA), growth differentiation factor-9 (GDF-9), follicle-stimulating hormone receptor (FSHR), and KIT LIGAND after vitrification/warming of human ovarian tissue. Methods: Human ovarian tissue samples were collected from five transsexual women. In the laboratory, the ovarian medullary part was removed by a surgical blade, and the cortical tissue was cut into small pieces. Some pieces were vitrified and warmed and the others were considered as non-vitrified group (control). Follicular normality was assessed with morphological observation by a light microscope, and the expression of FIGLA, KIT LIGAND, GDF-9,, and FSHR genes was examined using real-time RT-PCR in both the vitrified and non-vitrified groups. Results: Overall, 85% of the follicles preserved their normal morphologic feature after warming. The percentage of normal follicles and the expression of FIGLA, KIT LIGAND, GDF-9, and FSHR genes were similar in both vitrified and non-vitrified groups (P > 0.05). Conclusion: Vitrification/warming of human ovarian tissue had no remarkable effect on the expression of folliculogenesis-related genes.</p> Vitrification, Gene expression, Humans 220 225 http://ibj.pasteur.ac.ir/browse.php?a_code=A-10-1-563&slc_lang=en&sid=1 Zahra Shams Mofarahe No Marefat Ghaffari Novin mghaffarin@yahoo.com Yes Mina Jafarabadi No Mojdeh Salehnia No Mohsen Noroozian No Nassim Ghorbanmehr No
