the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Altered composition of the cumulus-oocyte complex matrix during in vitro maturation of oocytes.
BACKGROUND In vitro maturation (IVM) of mammalian oocytes has potential health benefits for patients undergoing assisted reproduction as an alternative to gonadotrophin treatment. This procedure is also useful for studying the process of oocyte and early embryo development. However, oocytes undergoing IVM have much lower competence than in vivo matured oocytes. Efforts to optimize IVM success h...
متن کاملEffect of Cumulus Oocyte Complex Morphology on in Vitro Maturation of Bovine Oocytes*
An experimental design was framed to analyse the effect of cumulus oocyte complex (COC) morphology on in vitro maturation of bovine oocytes. Slaughter house derived bovine ovaries from South Indian breeds and crossbred cattle of Kerala were subjected to three retrieval methods to yield different quality grades of oocytes. Based on the number of layers of cumulus cells and ooplasm character, the...
متن کاملEmbryological Aspects of Oocyte In Vitro Maturation
In Vitro Maturation (IVM) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. This review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. The review is based on literature reports and the author’s experience. In IVM cycles,...
متن کاملDynamic changes of cumulus-oocyte cell communication during in vitro maturation of porcine oocytes.
Oocyte maturation is a key issue of current animal biotechnology. This study was designed to examine the morphodynamics of the cumulus-oocyte association during oocyte maturation. Porcine cumulus-oocyte complexes were recovered from slaughterhouse ovaries; matured in vitro for 0, 24, 36, and 44 h; and evaluated by scanning electron microscopy either combined or not combined with the osmium-dime...
