P-107: Vitrification and In Vitro Culture of Mouse Preantral Follicles in Presence of Growth Factors
Background: Cryopreservation of oocytes is an effective technology in assisted reproductive technology. Although successful vitrification of gametes has been reported in several mammalian species, the survival is generally low. The aim of this study was to investigate the effects of fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) on preantral follicle development after vitrifi...
متن کاملRole of Follicle Stimulating Hormone in the Survival, Activation and Further Growth of in vitro Cultured Sheep Primordial Follicles
The aim of the present study was to investigate the effect of follicle stimulating hormone (FSH) on survival, activation and growth of ovine primordial follicles using histological studies. Pieces of ovine ovarian cortex were obtained and cultured for 6 days in Minimum Essential Medium supplemented with or without FSH (50 ng/mL). These fragments were then process to be used for histology compar...
متن کاملvitrification and subsequent in vitro maturation of mouse preantral follicles in presence of growth factors
objective: cryopreservation of ovarian tissue or follicles has been proposed as an alternative method for fertility preservation. although successful vitrification of follicles has been reported in several mammalian species, the survival rate is generally low. the aim of this study was to investigate the effects of fibroblast growth factor (fgf) and epidermal growth factor (egf) on in vitro pre...
متن کاملIn Vitro Growth of Mouse Preantral Follicles Under Simulated Microgravity
14 day-old mouse ovarian tissue and preantral follicles isolated from same-aged mice were incubated in a simulated microgravity culture system. We quantitatively assessed follicle survival, measured follicle and oocyte diameters, and examined ultrastructure of the oocytes produced from the system. We observed decreased follicle survival, downregulation of expressions of proliferating cell nucle...
متن کاملThe Effects of Fibroblast Co-Culture and Activin A on in vitro Growth of Mouse Preantral Follicles
Background: This study was conducted to evaluate fibroblast co-culture and Activin A on in vitro maturation and fertilization of mouse preantral follicles. Methods: The ovaries from 12-14-day-old mice were dissected, and 120-150 μm preantral follicles were cultured individually in α-MEM as based medium for 12 days. A total number of 456 follicles were cultured in four conditions: (i) base mediu...
