Journal ArticleDOI
Bovine Embryo Culture in the Presence or Absence of Serum: Implications for Blastocyst Development, Cryotolerance, and Messenger RNA Expression
Dimitrios Rizos,Alfonso Gutiérrez-Adán,S. S. Pérez-Garnelo,J. de la Fuente,Maurice P. Boland,Patrick Lonergan +5 more
TL;DR: It is shown that conditions of postfertilization culture, in particular, the presence of serum in the medium, can affect the speed of embryo development and the quality of the resulting blastocysts.
Journal ArticleDOI
Effects of in-vivo and in-vitro environments on the metabolism of the cumulus–oocyte complex and its influence on oocyte developmental capacity
TL;DR: Manipulation of factors including somatic cells of the follicle, composition of follicular fluid, and application of gained knowledge of the in-vivo environment may result in improved in- vitro oocyte maturation and overall in-Vitro embryo production.
Journal ArticleDOI
Errors in development of fetuses and placentas from in vitro-produced bovine embryos.
TL;DR: The term 'abnormal offspring syndrome (AOS)' is introduced and a classification system of developmental outcomes is proposed to facilitate research efforts on the mechanisms of the various abnormal phenotypes.
Journal ArticleDOI
Analysis of Differential Messenger RNA Expression Between Bovine Blastocysts Produced in Different Culture Systems: Implications for Blastocyst Quality
Dimitrios Rizos,Patrick Lonergan,Maurice P. Boland,Rosa Arroyo-García,Belén Pintado,J. de la Fuente,Alfonso Gutiérrez-Adán +6 more
TL;DR: The study of 7 differentially expressed mRNAs known to be involved in developmental process in the embryo suggests roles for apoptosis, oxidative stress, gap junctions, and differentiation in the determination of embryo quality.
Journal ArticleDOI
Factors affecting oocyte quality and quantity in commercial application of embryo technologies in the cattle breeding industry.
J.S. Merton,A.P.W. de Roos,Erik Mullaart,L. de Ruigh,L Kaal,Peter L.A.M. Vos,Steph J. Dieleman +6 more
TL;DR: It is concluded that an increased understanding of the processes of oocyte growth, pre- and final maturation will help to improve the efficiency of embryo technologies.

Mice carrying null mutations of the genes encoding insulin-like growth factor I (Igf-1) and type 1 IGF receptor (Igf1r)
Jeh-Ping Liu,Julie C. Baker,Archlbald S. Perkins,Elizabeth J. Robertson,Argiris Efstratiadis +4 more
TL;DR: In addition to generalized organ hypoplasia in Igf1r(-/-) embryos, including the muscles, and developmental delays in ossification, deviations from normalcy were observed in the central nervous system and epidermis.
Journal ArticleDOI
Parental imprinting of the mouse insulin-like growth factor II gene
TL;DR: It is demonstrated that IGF-II is indispensable for normal embryonic growth and that the IGF- II gene is subject to tissue-specific parental imprinting.
Journal ArticleDOI
Successful culture in vitro of sheep and cattle ova
TL;DR: This communication describes the successful culture of one-cell to eight-cell sheep ova and one- cell and eight- cell cattle ova to the morula and blastocyst stages and reports a high embryo survival after transfer of cultured Ova to recipient animals.
Journal ArticleDOI
Production of Cloned Calves Following Nuclear Transfer with Cultured Adult Mural Granulosa Cells
TL;DR: Adult somatic cell nuclear transfer was used to determine the totipotent potential of cultured mural granulosa cells, obtained from a Friesian dairy cow of high genetic merit, and DNA analyses confirmed that the calves are all genetically identical to the donor cow.
Journal ArticleDOI
Bovine embryo morphology and evaluation
TL;DR: Results suggest that transfer of bovine embryos based on synchrony between day of recipient cycle and state of embryonic development provides higher pregnancy rates than transfers based on recipient-donor cycle synchrony.
