In vitro Culture Conditions for the Mouse Preantral Follicles Isolated by Enzyme Treatment

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...

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...

Effect of Fibroblast Co-culture on In Vitro Maturation and Fertilization of Mouse Preantral Follicles

P-83: Development of Mouse Preantral Follicles in Fibrin-Alginate Matrix during In Vitro Culture

Background This research was conducted to assess preantral follicle development in fibrin alginate matrix following ovarian tissue vitrification MaterialsAndMethods Ovaries of 13-day-old NMRI female mice were removed and placed in control and vitrification groups. Vitrification group ovaries were transferred in media containing ethylene glycol, dimethyl sulphoxide, and sucrose then were plunged...

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...
