In vitro culture of goat preantral follicles
Background: The majority of thousands of oocytes in the ovaries are small, non-growing and reside in preantral follicles (PFs). The development of a culture system for preantral follicle may be very useful for understanding the complex mechanism in folliculogenesis at early stages of development as wells as could offer a significant way for the propagation of livestock, including goats. This pa...
متن کاملIn vitro culture of bovine preantral follicles.
Bovine preantral follicles (40-100 microm diameter at collection) were collected from ovaries of slaughtered cows and cultured in vitro with one of the four treatments: follicle stimulating hormone (FSH; 100 ng/ml) alone; FSH plus epidermal growth factor (EGF; 100 ng/ml); FSH plus insulin-transferrin-selenium (ITS; +1%) or FSH plus hypoxanthine (4 mM) in tissue culture medium (TCM 199) suppleme...
متن کاملP-28: The Effect of Hydrostatic Pressure on the In vitro Maturation of Preantral Follicles Derived from Polycystic Ovaries in Mouse Model
Background: Polycystic ovary syndrome (PCOS) is a multifactorial, heterogeneous, complex genetic endocrine and metabolic disorder, diagnostically characterized by chronic anovulation, polycystic ovaries and biochemical and clinical manifestations of hyperandrogenism. In patients with PCOS lower apoptotic rates found in granulosa cells compared to women with regular ovulatory cycles and this lea...
متن کاملSurvival Rate of Preantral Follicles Derived From Vitrified Mouse Ovarian Tissue by Cryotop
Purpose: The aim of this study was to investigate the growth and survival rate of preantral follicles isolated from vitrified ovarian tissue by cryotop.Materials and Methods: Ovaries of 14-day-old NMRI mice were separated and divided into three groups fowling as: vitrified, toxicity tested and control groups. Ovaries in the experimental groups were immersed in equilibration and vitrification so...
متن کاملP-88: Expression Pattern of Maturation Genes During In Vitro Culture of Alginate Encapsulated Preantral Follicles Derived From Frozen-Thawed Mouse Ovaries
Background: This study was set up to evaluate the effect of ovarian tissue slow freezing on in vitro growth and pattern of maturation genes expression in mouse preantral follicles encapsulated within alginate hydrogel. Materials and Methods: Ovaries of 12-14 days old female NMRI mice were randomly allocated into control and slow freezing groups. In slow freezing group, ovaries were equilibrated...
