In 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 کاملUltrastructure and viability of isolated bovine preantral follicles.
Techniques for the isolation of ovarian follicles and maturation of oocytes in vitro have enormous reproductive potential. Preservation of normal tissue function is vital. This study emphasizes the ultrastructure and viability of mechanically isolated bovine small (diameter 40-100 microm) preantral and large (140-450 microm) preantral/early antral follicles. Viability studies were performed for...
متن کاملEffects of α - tocopherol and ternatin antioxidants on morphology and activation of goat preantral follicles in vitro cultured
The effects of α-tocopherol and ternatin on the morphology, activation, and growth of goat preantral follicles in vitro cultured, for one or five days, were evaluated. Ovarian fragments were immediately fixed (non-cultured control) or in vitro cultured for one or five days in Minimum Essential Medium (MEM) with or without α-tocopherol or ternatin supplementation, both at concentrations of 5, 10...
متن کاملIn vitro culture of bovine preantral follicles: a review
Preantral follicles are the majority of the ovarian follicle population and their use as a source of homogeneous oocytes for bovine reproductive biotechnologies could result in a substantial advance in this field. However, while in other species embryos and offspring have been produced, in bovine species the results have been limited to the follicular activation of small (primordial) preantral ...
متن کاملP-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...
