Selection of Ovine Oocytes by Brilliant Cresyl Blue Staining
Sheep oocytes derived from the ovaries collected from the slaughterhouse are often used for research on in vitro embryo production, animal cloning, transgenesis, embryonic stem cells, and other embryo biotechnology aspects. Improving the in vitro culture efficiency of oocytes can provide more materials for similar studies. Generally, determination of oocyte quality is mostly based on the layers...
متن کاملDevelopmental competence of prepubertal goat oocytes selected with brilliant cresyl blue and matured with cysteamine supplementation.
The aim of this study was to assess the effect of oocyte selection using the brilliant cresyl blue (BCB) test plus the addition of cysteamine to the in vitro maturation (IVM) medium to improve the in vitro embryo development of prepubertal goat oocytes. The oocytes were exposed to 26 microM BCB and classified according to their cytoplasm coloration: BCB+ (oocytes with blue cytoplasm) and BCB- (...
متن کاملCholesterol added prior to vitrification on the cryotolerance of immature and in vitro matured bovine oocytes
This study examines whether incorporating cholesterol-loaded methyl-β-cyclodextrin (CLC) in the bovine oocyte plasma membrane improves oocyte tolerance to vitrification. In vitro matured oocytes were incubated with 2 mg/ml BODIPY-labeled CLC for different time intervals in FCS or PVA supplemented medium or exposed to different CLC concentrations to examine the subcellular localization of choles...
متن کاملBrilliant Cresyl Blue in Sap of Nitella
It has been shown by several investigators I that when the pl-I value of the external dye solutions is increased, the rate of accumulation of a basic dye in the cell sap is accelerated. Two different explanations for this have been given. Some have accounted for it on the basis that the basic dye enters the cell in the form of a dye hydrate and combines with the substances in the cell; and that...
