Impact of pro-oxidant agents on the morula-blastocyst transition in bovine embryos.
Exposing day 5 bovine morulae to reactive oxygen species induces a delayed degeneration of some blastocysts on day 8 post-insemination (pi) but without affecting the blastocyst rates. The aim of this study was to characterize the resisting and the degenerating population of blastocysts. The kinetics of degeneration of the embryos exposed to the two pro-oxidant agents: 2,2'-azobis (2-amidinoprop...

Retinoids during the in vitro transition from bovine morula to blastocyst.
BACKGROUND The conversion of retinol (ROH) to retinoic acid (RA) is crucial during development but has been not studied during blastocyst formation. METHODS AND RESULTS In vitro-produced bovine morulae were treated for 24 h with citral (which inhibits the synthesis of RA from ROH), citral + all trans retinoic acid (ATRA), ATRA or no additives. Citral interfered with blastocyst development, wh...
متن کاملthe effect of biopsy during precompacted morula stage on post vitrification development of blastocyst derived bovine embryos
improvements on embryo micromanipulation techniques led to the use of embryo biopsy in commercial embryo transfer programs for genetic analysis of preimplantation bovine embryos. the aim of this study was to evaluate the quality of bovine blastocyst derived from embryos biopsied at different precompacted morulae stages by assessment of cryosurvivability of the resulting blastocysts. the in vitr...
