Cyclic AMP affects oocyte maturation and embryo development in prepubertal and adult cattle
Bernal Ulloa, Sandra Milena; Heinzmann, Júlia; Herrmann, Doris; Hadeler, Klaus Gerd; Aldag, Patrick; Winkler, Sylke; Pache, Dorit; Baulain, Ulrich (2016)High cAMP levels during in vitro maturation (IVM) have been related to improved blastocyst yields. Here, we employed the cAMP/cGMP modulators, forskolin, IBMX, and cilostamide, during IVM to unravel the role of high cAMP ... -
Effects of different oocyte retrieval and in vitro maturation systems on bovine embryo development and quality
Bernal Ulloa, Sandra Milena; Heinzmann, Julia; Herrmann, Doris; Timmermann, Bernd; Baulain, Ulrich; Großfeld, Rudolf; Diederich, Mike (2013-04)Cyclic adenosine monophosphate (cAMP) modulators have been used to avoid spontaneous oocyte maturation and concomitantly improve oocyte developmental competence. The current work evaluated the effects of the addition of ... -
Oocyte pre-IVM with caffeine improves bovine embryo survival after vitrification
Bernal Ulloa, Sandra Milena; Lucas Hahn, Andrea; Herrmann, Doris; Hadeler, Klaus; Aldag, Patrick (2016)Cryopreservation of in vitro produced bovine embryos is associated with significantly reduced survival rates, mainly due to insufficient quality of the embryos. Caffeine supplementation during IVM has been used to delay ...
