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 کاملInhibin A and B secretion in mouse preantral follicle culture.
Conditioned media from single mouse ovarian follicles cultured from the early preantral stage up to complete maturity were analysed for different immunoreactive inhibin forms. The inhibin assays measured (i) alpha-specific inhibin, as represented by a mix of 32 and and 57 kDa inhibins, inhibin precursors, alpha-subunit and its precursors; (ii) dimeric inhibin A; and (iii) dimeric inhibin B. The...
متن کاملIn vivo and in vitro strategies to support caprine preantral follicle development after ovarian tissue vitrification.
The aim of the present study was to compare fresh and vitrified goat ovarian tissue after autotransplantation and in vitro culture. Adult goats were completely ovariectomised and each ovarian pair was sliced and distributed among six different treatment groups: fresh control, fresh transplant, fresh culture, vitrified control, vitrified transplant and vitrified culture. Follicular morphology, d...
متن کاملP-46: Vitrification of Mouse Ovaries Under Magnefic Field
Background The aim of this study was to investigate the effect of applying the 1-mT magnetic field (MF) in the ovarian tissue vitrification. MaterialsAndMethods Ovaries of 6-8 week-old Naval Medical Research Institute female mice randomly were divided into 5 groups: V1: Ovaries that immediately after leaving of the mice body, were examined histologically (control group), V2: Ovaries that withou...
متن کاملP-98: Effect of Mouse Embryo Vitrification on Histone Modifications
Background: Vitrification has been usually used as an assisted reproductive technology in animals and humans. This method needs high concentrations of cryoprotectants that can be toxic with high cooling degrees. Then, vitrification could be change histone modifications such as methylation and acetylation can performance as regulatory controls of gene transcription. So, the purpose of the presen...
