Chromatin modifications in the germinal vesicle (GV) of mammalian oocytes.
The nucleus of eukaryotic cells is organized into functionally specialized compartments that are essential for the control of gene expression, chromosome architecture and cellular differentiation. The mouse oocyte nucleus or germinal vesicle (GV) exhibits a unique chromatin configuration that is subject to dynamic modifications during oogenesis. This process of 'epigenetic maturation' is critic...
متن کاملP-217: The Effect of Progesterone on The In Vitro Maturation of Mouse Germinal Vesicle Oocytes Derived from Polycystic Ovary
Background: Polycystic ovary syndrome (PCOS) is characterized by chronic anovulation and hyperandro genism and affects approximately 5-10% of women of reproductive age. In vitro maturation (IVM) of mammalian oocytes has become an efficient method to produce mature oocytes in order to use in assisted reproductive techniques such as in vitro fertilization (IVF), intra cytoplasmic sperm injection ...

متن کاملVitrification of human germinal vesicle oocytes; before or after in vitro maturation?
Background The utilization of immature oocytes derived from stimulated cycles could be of great importance, specially for urgent fertility preservation cases. The aim of the current study was to determine whether in-vitro maturation is more successful before or after the vitrification of these oocytes. MaterialsAndMethods The study was performed in a private IVF center. 318 germinal vesicle (GV...
متن کاملReconstruction of mammalian oocytes by germinal vesicle transfer: A systematic review
Nuclear transfer procedures have been recently applied for clinical and research targets as a novel assisted reproductive technique and were used for increasing the oocyte activity during its growth and maturation. In this review, we summarized the nuclear transfer technique for germinal vesicle stage oocytes to reconstruct the maturation of them. Our study covered publications between 1966 and...
