Journal ArticleDOI
Cellular and Molecular Deviations in Bovine In Vitro-Produced Embryos Are Related to the Large Offspring Syndrome
Giovanna Lazzari,Christine Wrenzycki,Doris Herrmann,Roberto Duchi,T.A.M. Kruip,Heiner Niemann,C. Galli +6 more
TL;DR: The hypothesis that persistence of early deviations in development is causally involved in the incidence of LOS, in particular in increased birthweights, is supported.
Journal ArticleDOI
Alterations in the relative abundance of gene transcripts in preimplantation bovine embryos cultured in medium supplemented with either serum or PVA
TL;DR: Timing and magnitude of the alterations varied among the different transcripts and were significantly affected by the presence of exogenous protein in a stage‐specific manner, predominantly at critical developmental time points, suggesting that alterations in mRNA expression are associated with culture environment.
Journal ArticleDOI
Nuclear Transfer Protocol Affects Messenger RNA Expression Patterns in Cloned Bovine Blastocysts
Christine Wrenzycki,David N. Wells,Doris Herrmann,A.L. Miller,J. E. Oliver,R. Tervit,Heiner Niemann +6 more
TL;DR: An aberrant expression pattern in NT embryos was found with respect to genes thought to be involved in stress adaptation, trophoblastic function, and DNA methylation during preimplantation development.
Journal ArticleDOI
Effects of in vivo prematuration and in vivo final maturation on developmental capacity and quality of pre-implantation embryos
Steph J. Dieleman,P.J.M. Hendriksen,D. Viuff,Preben D. Thomsen,Poul Hyttel,H.M. Knijn,Christine Wrenzycki,T.A.M. Kruip,Heinrich Niemann,Barend M. Gadella,M.M. Bevers,Peter L.A.M. Vos +11 more
TL;DR: It is shown that the natural environment during final maturation is not essential for the mere in vitro development of the prematured oocyte beyond the 8- to 16-cell stage, and that the beneficial effects of in vivo maturation are possibly exerted at initial stages of embryonic development.
Journal ArticleDOI
In Vitro Production and Nuclear Transfer Affect Dosage Compensation of the X-Linked Gene Transcripts G6PD, PGK, and Xist in Preimplantation Bovine Embryos
TL;DR: Results of the present study show for the first time that differences in X-chromosome-linked gene transcript levels are related to a perturbed dosage compensation in female and male IVP and female NT-derived embryos.
