Cryotop and development of vitrified immature bovine oocytes
The effectiveness of different cryodevices (open-pulled straw (OPS), electron microscopy grid (EMG), and Cryotop was evaluated for vitrification of immature bovine oocytes. Polar body, metaphase II stage (MII), survivability, and subsequent developmental rates were determined. Only oocytes with four or five layers of cumulus cells were used. Oocytes were equilibrated in two vitrification soluti...
متن کاملEffect of cryoprotectant composition on in vitro viability of in vitro fertilized and cloned bovine embryos following vitrification and in-straw dilution.
In this study the efficacy of the combination of glycerol (GLY) and ethylene glycol (EG) as cryoprotectants in a vitrification method developed for direct embryo transfer was evaluated by in vitro development of in vitro fertilized (IVF) and somatic cell nuclear transfer (SCNT) embryos after vitrification. The IVF and SCNT blastocysts were vitrified in either 40% GLY, 30% GLY + 10% EG, or 20% G...
متن کاملViability And DNA Fragmentation Assessment Of Bovine Embryos Vitrified By Different Methods
This study was conducted to compare the efficiency of four vitrification methods: straws in goblet, straws in Hasler device, cryloop and cryotop methods on blastocyst viability and the extent of apoptosis using the TUNEL technique in bovine embryos. Blastocysts were produced in vitro by standard procedures. The base medium for vitrification was Syngro holding medium. Embryos were vitrified by t...
متن کاملIntrauterine embryo transfer with canine embryos cryopreserved by the slow freezing and the Cryotop method
Canine embryos (8-cell to blastocyst stages) frozen-thawed using the slow-freezing method with glycerol (four recipients) or dimethyl sulfoxide (three recipients) as a cryoprotectant and vitrified-warmed using the Cryotop method (five recipients) were surgically transferred into the unilateral uterine horn of recipient bitches. As a result, the morphology of embryos frozen-thawed using the slow...
متن کاملCryopreservation of common carp (Cyprinus carpio) embryos using different cryoprotectant
This study reports that common carp (Cyprinus carpio) embryos were successfully frozen and preserved by vitrification. The modified Haga solution was tested by using two different cryoprotectants and three different concentrations at 4°C to obtain appropriate vitrified solutions ((dimethylsulfoxide 5, 10, 15% (DMSO) and glycerol 5, 10, 15% (gly)) in the study. The hatching rates of embryos exp...
