Development of mammalian ovary.

The roles of RFamide-related peptides (RFRPs), mammalian gonadotropin-inhibitory hormone (GnIH) orthologues in female reproduction

Objective(s): To benefit from reproduction and deal with challenges in the environmental conditions, animals must adapt internal physiology to maximize the reproduction rate. Maladaptive variations in the neurochemical systems and reproductive system can lead to manifestation of several significant mammalian reprocesses, including mammalian ovarian lifespan. RFamide-related peptide (RFRP, Rfrp)...

P-254: The Effects of Zinc in Vitrification Medium on In vitro Maturation of Oocytes Derived from Vitrified-Warmed Mouse Ovary

Background: Cryopreservation of ovarian tissue is an important option for preserving the fertility of cancer patients undergoing chemotherapy and radiotherapy. Researchers have used different cryoprotectants and various techniques to improve the cryopreservation of ovaries However, despite significant recent progress, the efficiency of ovary cryopreservation is still low. Zinc is essential for ...

P-70: Evidence for Differential Gene Expression of A Major EpigeneticModifier Enzyme, de novo DNA Methyltransferase 3b, through Vitrification of Mouse Ovary Tissue

Background: Ovarian tissue cryopreservation is a feasible method to preserve female reproductive potential, especially in young patients with cancer or in women at risk of premature ovarian failure. Vitrification has recently emerged as a new trend for biological specimen preservation. On the other hand, gene expression that changes during vitrification can influence oocyte maturation and need ...

P-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 ...

Steroid Production and Follicular Development of Neonatal Mouse Ovary during In Vitro Culture

Using transient transfected Chinese hamster ovary (CHO) cells by pET28a-LIC-NTF4 in gene therapy

Introduction: Neurotrophins, as a family of proteins, are responsible for induction of the survival, development, and function of neurons. Also, neurotropic factors are growth factors like Neurotrophins that help neurons survive. Moreover, Neurotrophins differentiate between progenitor cells so that neurons are formed. Despite the fact that the majority of mammalian brain neurons are produced p...
