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.
P-64: Anthocyanin Effects on Sheep Oocytes In Vitro Maturation in The Presence of cAMP Modulators.
Background We have previously reported the effect of Anthocyanin and cAMP modulators on maturation and apoptosis of sheep oocytes. In this study, we investigated the reduction capacity and apoptotic gene expression results at MII sheep oocytes. MaterialsAndMethods Good ovine Cumulus-oocyte complexes (COCs) were transferred to Pre-IVM medium, then to two type IVM mediums: 1) 0.1μg/ml Delphinidin...
متن کاملUltrastructural Changes of Sheep Oocytes Follow Vitrification by Different Methods and In Vitro Maturation
Purpose: Our aim was determination of the sheep oocytes ultrastructural changes follow vitrification and in vitro maturation. Materials and Methods: Good quality isolated cumulus-oocyte complexes (COCs) were randomly divided into non-vitrified control, conventional straw, cryotop and solid surface vitrification groups. In the conventional and cryotop methods the vitrified COCs were plunged dire...
متن کاملEffect of kisspeptin on in vitro maturation of sheep oocytes
AIM The aim of this study was to investigate the effect of kisspeptin (KP) on in vitro maturation (IVM) of sheep oocytes aspirated from the ovaries collected from slaughterhouse. MATERIALS AND METHODS Two different experiments were conducted to investigate the effect of KP (5, 10 and 15 µg/ml) alone (experiment 1) or in combination with follicle-stimulating hormone (FSH), luteinizing hormone ...
