P-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...
متن کاملO-11: Diverse Effects of Polyunsaturated Fatty Acids on Oocyte Maturation and Development In vitro
Background: Polyunsaturated fatty acids (PUFAs) have been shown to influence fertility and endocrinology of reproduction and metabolic activity in many species. In dairy cows, we and others have shown changes in steroid and metabolic hormones and prostaglandins leading to alteration of ovarian activity and uterine function. These can influence fertility by changes in folliculogenesis cyclicity ...
متن کاملThe Study on Expression of Mous Oocyte and Preimplantation Embryc Mct1 and Mct3 Genes in Vivo and in Vitro
Purpose: The aim of this study was to assay the profile of MCT1 & MCD in mouse unfertilized & fertilized oocytes and preimplantation embryos In vivo and In vitro. Materials and Methods: The presence of mRNAs encoding MCT1 & MCD3 were determined On unfertilized and fertilized oocytes, 2-cell, morulae, blastocyst and cultured embryos in plus glucose KSOM, minus glucose KSOM and pulse glucose KSO...
متن کاملDifferential Effect of Medium on the Ratio of ICM/TE of Bovine Embryos in a Co-culture System
Background This study was undertaken to investigate the efficiency of two different embryo somatic cell co-culture conditions tissue culture medium 199 (TCM199)–vero cells and Menezo B2 (B2)-vero cells for the in vitro developmental quantity and quality of bovine embryos. MaterialsAndMethods Bovine oocytes were allowed to mature and subsequently undergo fertilization in vitro. Their presumptive...
متن کاملAberrant expression of maternal Plk1 and Dctn3 results in the developmental failure of human in-vivo- and in-vitro-matured oocytes
Fertilisation is the first step in embryonic development, and dynamic changes of key genes may potentially improve assisted reproduction techniques efficiency during this process. Here, we analysed genes that were differentially expressed between oocytes and zygotes and focused on cytokinesis-related genes. Plk1 and Dctn3 were identified as showing dramatic changes in expression during fertilis...
