The aim of the present study was to assess the maturational competence and the cytoskeletal pattern of bovine oocytes reconstructed by a germinal vesicle transplantation (GVT) technique using nuclear and/or cytoplasmic components from cryopreserved G

Reactive oxygen species (ROS) are produced under normal culture conditions, but when production increases, it generates a harmful condition called oxidative stress (OS), leading to apoptosis and developmental blocks. Addition of antioxidants as melat

Prepubertal bovine females have been suggested as a source of oocytes in order to accelerate genetic gain and decrease the generation interval. However, prepubertal oocytes have a lower developmental competence than their adult counterparts. In vitro

Cell co-culture during in vitro maturation or embryo culture has been reported as a method to improve the efficiency of maturation or embryo development (Kidson et al. 2003 Theriogenology 59, 1889; Romar et al. 2005 Anim. Reprod. Sci. 85, 287). Here,

Enucleation in traditional nuclear transfer (NT) is an invasive procedure for which alternative protocols have been sought. The present study was designed to explore the time course effects of demecolcine, a microtubule-depolymerizing agent, in bovin

Assisted reproduction technologies (ARTs) are achieving increasing prominence in reproductive medicine. With the increasing application of ARTs comes increased interest in optimizing efficiency while minimizing potential risks to the offspring. One a

Mitogen-activated protein kinase (MAPK) is involved in many signal processes within eukaryotic organisms. Its active form is phosphorylated. For meiotic resumption in oocytes the MAPK cascade plays a central role, because it participates in the trans

The Eld’s deer, native to Southeast Asia, is threatened with extinction. Although artificial insemination is effective for offspring production, in vitro fertilization (IVF) would be more useful for rapidly disseminating genetic material from valua
