Melatonin Improves The Developmental Competence of Goat Oocytes
Objective DNA methylation is one the epigenetic mechanisms, which is critically involved in gene expression. This phenomenon is mediated by DNA methyl-transferases and is affected by environmental stress, including in vitro maturation (IVM) of oocytes. Melatonin, as an antioxidant, may theoretically be involved in epigenetic regulation via reductions of reactive oxygen species. This study was p...
متن کاملDevelopmental competence of Dromedary camel oocytes fertilized in vitro by frozen-thawed ejaculated and epididymal spermatozoa
The present study aimed to compare the in vitro fertilizing capacity of frozen-thawed ejaculated and epididymal spermatozoa in order to standardize the semen preparation protocol for camel in vitro fertilization (IVF). Semen samples were collected from 7 Dromedary camels by means of artificial vagina (AV). Ten cauda epididymes were obtained from slaughtered adult camels, isolated, incised and r...
متن کاملCryopreservation of metaphase II human oocytes effects mitochondrial membrane potential: implications for developmental competence.
BACKGROUND Current outcome results with embryos derived from thawed MII human oocyes are significantly lower than with embryos cryopreserved at the pronuclear stage. Here, we investigated whether freezing-thawing was associated with changes in oocyte mitochondrial polarity (DeltaPsim) that could influence competence by altering ATP levels or the ability of the cytoplasm to regulate intracellula...
متن کاملP-118: Developmental Competence of Ovine Embryos Derived from Frozen Oocytes Co-Cultured with Embryos Derived from Fresh Oocytes
Background: Currently, a limited number of studies have been done on the vitrification of small ruminant oocytes, especially in sheep, where poor developmental rates are obtained following immature and mature oocyte vitrification. Poor ovine oocyte cryopreservation could attribute to the damage to enzymes which has role in metabolic pathways. Therefore, production of cytokines and growth factor...
