RECENT ADVANCES IN OOCYTES IN-VITRO MATURATION PROCESS IN BOVINES

Abstract

Cattle play a vital role in national economy; therefore, the cattle population must be raised by all possible ways of production. Maturation of oocytes outside the body of animal is principal method in dairy production field which is used to produce the mature oocytes for pre-implantation embryo development. This technology has great potential to increase efficiency for both clinically and commercially purposes. In the last few decades, the progress in in-vitro Maturation (IVM) of oocytes has been very slow. Many factors affects the IVM of oocytes. However pre-IVM with cAMP modulators could contribute to the acquisition of developmental competence by bovine oocytes from small antral follicles through the modulation of EGF receptor signaling and oocyte-cumulus/cumuluscumulus gap junctional communication, however, the main aim of the review is to understand the ability of oocyte development and its control mechanism during in-vivo and in-vitro processes. In addition, the various perspectives of in-vitro maturation of oocytes in bovines have also been discussed
