Abstract

Biotechnologies for cloning animals and in vitro embryo production have the potential to produce biomedical models for various researches. Especially, pigs are a suitable model for xenotransplantation, transgenic production and various areas of reproductive research due to its physiological similarities to human. However, utilization of in vitro-produced embryos for transfer remains limited. Despite improvement over past few decades, obstacles associated with the production of good quality embryos in vitro still exist which limit the efficiency of cloning. One of major problems includes improper in vitro maturation (IVM) and culture (IVC). Oxidative stress caused from in vitro culture conditions contributes to inadequate IVM and IVC which leads to poor developmental competence of oocytes, failure of fertilization and embryo development. To reduce the oxidative stress, various antioxidants have been used to IVM and IVC system. However, limited information is available on the effects of resveratrol on livestock reproductions. Resveratrol is a polyphenolic natural product and well known as an antioxidant in foods and beverages (e.g. in grapes and red wine). Resveratrol is known to be cardioprotective, anticarcinogenic, anti-inflammatory, antioxidant and antiapoptotic. This paper will review the effects of resveratrol on in vitro maturation of oocytes and embryo development.
