Cycloheximide and 6‐dimethylaminopurine (6‐DMAP) are widely used in protocols of somatic cell nuclear transfer (SCNT) for inhibition of maturation promoting factor (MPF) activity in SCNT-oocytes in the post-activation period of their culture. Nev

As has been shown previously, fibroblast growth factor 2 (FGF2), leukaemia inhibitory factor (LIF), and insulin-like growth factor 1 (IGF1) in combination play a positive role in maintaining the quality of mammalian oocytes maturing invitro. In the p

The final stages of IVM are of great importance for the developmental competence of mammalian oocytes. The goal of the present work was to study effects of prolactin (PRL) and progesterone (PG) during the completion of IVM in serum-containing and ser

The efficiency of assisted reproductive technologies is critically dependent on the quality of the oocytes used to produce the embryos. The aim of the present research was to study dose-dependent effects of three cytokines: fibroblast growth factor 2

To date, considerable progress has been achieved in in vitro production (IVP) technologies in cattle; however, developmental potentials of oocytes matured in vitro remain low compared with in vivo-matured oocytes. Thus, a better understanding of diff

Maturing mammalian oocytes can prevent luteinization of cumulus cells (CC) both in vivo and in vitro by regulating CC steroidogenesis (Gilchrist et al. 2004 Anim. Reprod. Sci. 82-83, 431-446; Ramirez et al. 2016 Anim. Reprod. 14, 280). However, when

Data on effects of progesterone (P4) during in vitro maturation of bovine oocytes on their capacity for embryonic development are contradictory. Our study was aimed at characterising effects of P4 and 2 luteotropic hormones, prolactin (PRL) and LH, o

The technique of somatic cell nuclear transfer includes a delayed activation of reconstituted oocytes (4–6 h after IVM). The prolonged culture of mammalian oocytes is known to be associated with aging of the ova leading to a decline in their qualit

Interspecies hybrids are important resources for research and agriculture. Therefore, the aim of this study was to evaluate development, quality, and viability of embryos produced in vitro using cattle (Bos taurus) oocytes and European bison (Bison b
