the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
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...

15 صفحه اولDevelopmental competence of bovine embryos reconstructed by the transfer of somatic cells derived from frozen tissues.
The ability of frozen-thawed fetal skin was examined to generate viable cell lines for nuclear transfer. Fetal skin frozen at -35 degrees C or -80 degrees C in the presence of 5% DMSO were used as tissue explants to generate somatic cells. The resultant confluent cells were then used as donors for nuclear transfer (NT). Of the bovine NT embryos reconstructed from the somatic cells, 78% to 81% s...
متن کاملStage-specific effect of growth hormone on developmental competence of bovine embryos produced in-vitro.
Many efforts have been made to develop effective culture conditions for the production of bovine blastocysts. Growth hormone (GH) and glucose are known to affect in vitro embryo development. To improve in vitro culture conditions, the culture medium containing fetal calf serum (FCS) or bovine serum albumin (BSA) was supplemented with GH at various periods of development, and the effects of GH o...
