In vitro survival of in vitro-produced bovine embryos cryopreserved by slow freezing, fast freezing and vitrification
In order to compare the survival rate of bovine embryos cryopreserved with different protocols, oocytes obtained from abattoir-derived ovaries were used for in vitro maturation (IVM), fertilization (IVF) and co-culture. Expanded blastocysts were cryopreserved by two slowfreezing [(i) 0.5 and (ii) 1.2°C/min], (iii) one quickfreezing and two vitrification [(iv) ethylene glycol + ficoll + sucrose ...
متن کاملTranscriptomic difference in bovine blastocysts following vitrification and slow freezing at morula stage
Cryopreservation is known for its marked deleterious effects on embryonic health. Bovine compact morulae were vitrified or slow-frozen, and post-warm morulae were cultured to the expanded blastocyst stage. Blastocysts developed from vitrified and slow-frozen morulae were subjected to microarray analysis and compared with blastocysts developed from unfrozen control morulae for differential gene ...
متن کاملIn vitro survival rate of bovine oocytes following vitrification in glass capillary micropipette (GCM)
The purpose of this study was to evaluate the use of glass capillary micropipette (GCM) as a vessel forvitrification of bovine oocytes. Cumulus-oocyte complexes (COCs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (TCM-199 + 20% FBS) and randomly assigned to treatment andcontrol group. In the first step of vitrification, COCs were exposed to first vitrification...
متن کاملStimulatory effect of ROCK inhibitor on revivability of in vitro-produced bovine blastocysts after vitrification
Inhibition of Rho-associated coiled-coil kinase (ROCK) activity has been reported to promote recovery and growth of frozen-thawed human embryonic stem cells. Since in vitro-produced and/or manipulated bovine embryos are sensitive to cryopreservation, the present study was conducted to investigate whether the presence of ROCK inhibitor (Y-27632) in post-thaw culture medium improve the revivabili...
متن کاملSerum free embryo culture medium improves in vitro survival of bovine blastocysts to vitrification.
The aim of this study was to examine the effects of co-culture with Vero cells during the in vitro maturation (IVM) and three culture media, B2+5% fetal calf serum (FCS) on Vero cells, synthetic oviduct fluid (SOF)+5% FCS, and SOF+20 gL(-1) bovine serum albumin (BSA), on the developmental competence of the embryos and their ability to survive vitrification/warming. We also tested the effect of ...
