Optimization of cryoprotectant loading into murine and human oocytes.
Loading of cryoprotectants into oocytes is an important step of the cryopreservation process, in which the cells are exposed to potentially damaging osmotic stresses and chemical toxicity. Thus, we investigated the use of physics-based mathematical optimization to guide design of cryoprotectant loading methods for mouse and human oocytes. We first examined loading of 1.5 M dimethyl sulfoxide (M...
متن کاملDevelopment and viability of bovine embryos derived from oocytes matured and fertilized in vitro and co-cultured with bovine oviducal epithelial cells.
A co-culture system using a suspension of detached bovine oviducal epithelial cells (BOEC) has been developed as an effective culture method for supporting the development of bovine embryos derived from oocytes matured and fertilized in vitro. Four commercially available culture media (Waymouth's, Ham's F-10, TCM 199 and Ménézo's B2) supplemented with 10% oestrous cow serum, and a modified Tyro...
متن کاملP-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...
متن کاملEvaluation of polyvinylpyrrolidone as a cryoprotectant for adipose tissue-derived adult stem cells.
The objective of this study was to test the hypothesis that human adipose tissue-derived adult stem cells (ASCs) can be effectively cryopreserved and stored in liquid nitrogen using a freezing medium containing a high-molecular-weight polymer, polyvinylpyrrolidone (PVP), as the cryoprotective agent (CPA) instead of dimethylsulfoxide (DMSO). To this end we investigated the postfreeze/thaw viabil...
متن کاملCurrent status of vitrification of embryos and oocytes in domestic animals: ethylene glycol as an emerging cryoprotectant of choice.
The cryopreservation of mammalian embryos has become an integral part of methods to control animal reproduction. Numerous vitrification solutions have been formulated with ethylene glycol in combination with macromolecules, sugars and other cryoprotective agents. These indicate that a study of ethylene glycol as a cryoprotectant of choice in vitrification studies would be promising. To understa...
