Improvement in Bovine Embryo Production In Vitro
Bovine oocytes were matured, fertilized, and cultured FCM 199 with serum and co-culture) in vitro (IVMFC) with addition, during different phases of the procedure, of antioxidants: superoxide dismutase (SOD) and reduced glutathione (GSH). The addition of SOD (1,500 or 3,000 IU/ml) did not improve proportions of oocytes undergoing cleavage or the development of embryos to morula and blastocyst st...
متن کاملBovine In vitro Embryo Production : An Overview
Dairy industry perfected the application of the first reproductive biotechnology, i.e. artificial insemination (AI) a great success story and also remains the user of embryo transfer technology (ETT). In addition, recently the researchers taking interest to embraced the field of Transvaginal Oocyte Recovery (TVOR) and in vitro production (IVEP) of embryos. IVF provides the starting point for th...
متن کاملThyroid hormone supplementation improves bovine embryo development in vitro.
BACKGROUND Early embryo development (EED) forms the basis of assisted reproductive technologies (ARTs), which are used to treat human infertility and to propagate other mammalian species. Thyroid hormones (THs) play an important role in the post-implantation development of the embryo in mammals; however, the effects of THs on pre-attachment embryos are not known. Currently utilized in-vitro emb...
متن کاملReactive oxygen species in bovine embryo in vitro production.
Oxidative modifications of cell components due to the action of reactive oxygen species (ROS) is one of the most potentially damaging processes for proper cell function. However, in the last few years it has been observed that ROS participate in physiological processes. The aim of this work was to determine ROS generation during in vitro production of bovine embryos. Cumulus-oocyte complexes we...
متن کاملMenaquinone (vitamin K2)-6 production by mutants of Flavobacterium meningosepticum.
Flavobacterium meningosepticum IFO 12535, a menaquinone (MK) producer, was mutagenized to improve productivity. A mutant, which was resistant to 1-hydroxy-2-naphthoate (HNA), was found to produce MK more abundantly: 34 mg/liter of culture broth and 5.5 mg/g of dry cells. The mutant was less sensitive to inhibition by HNA on MK biosynthesis than the wild-type strain. MK was isolated from cells o...
