A dose-dependent response to MEK inhibition determines hypoblast fate in bovine embryos
(BioMed Central, 2019-07-04)Background: The segregation of the hypoblast and the emergence of the pluripotent epiblast mark the final stages of blastocyst formation in mammalian embryos. In bovine embryos the formation of the hypoblast has been ... -
Characterization of CD79acy + cells in placentas from ruminants
(Elsevier, 2019-11)Previous work carried out to characterise different immune cells in ruminant placentas found strong CD79αcynuclear labelling in cells histologically resembling trophoblast cells. In the attempt to characterize this ... -
Development and growth of bovine calves demi-embryos
(Elsevier, 2023-12)The aim of this study was to investigate the growth and development of animals produced from demi-embryos and compare them with whole embryos from fetus to adult life. To achieve this, calves produced from fresh demi-embryos ... -
Effect of Campylobacter fetus on in vitro fertilization and embryonic development of preimplantation bovine embryos
(Elsevier, 2024-01)Campylobacter fetus is an important veterinary pathogen that causes campylobacteriosis. This disease causes decreased productivity of cattle by inducing reproductive losses. Although several virulence factors have been ... -
Embryo yield in llamas synchronized with two different intravaginal progesterone-releasing devices and superovulated with eCG
(2015)The objectives of this study were to compare the effects of two intravaginal devices (ID) containing the same dose (0.5 g) of progesterone (P4) on subsequent ovarian response, embryo production and circulating P4 concentration ... -
Evaluación de un protocolo de superovulación con el uso de eCG recombinante en ovejas Dohne Merino = Evaluation of a superovulation protocol with the use of recombinant eCG in Dohne Merino sheep
(Asociación Argentina de Producción Animal, 2022-11-16)La producción y transferencia de embriones es una herramienta biotecnológica que permite incrementar los procesos de mejora genética, aprovechando las características productivas de hembras y machos de alto valor genético. ... -
Molecular Characterization of the First Bovine Herpesvirus 4 (BoHV-4) Strains Isolated from In Vitro Bovine Embryos production in Argentina
(Plos One, 2015-07-15)Bovine herpesvirus 4 (BoHV-4) is increasingly considered as responsible for various problems of the reproductive tract. The virus infects mainly blood mononuclear cells and displays specific tropism for vascular endothelia, ... -
Nuevas estrategias para mejorar la eficiencia del semen sexado en producción in vitro de embriones bovinos
(Facultad de Ciencias Veterinarias, Universidad Nacional del Litoral, 2017)El objetivo de esta tesis fue el de optimizar el uso de semen sexado en embriones bovinos producidos in vitro (PIVE). Para ello se realizaron tres estudios con el fin de evaluar: diferentes medios de fecundación in vitro ... -
¿Por qué y para qué producir embriones bovinos in vitro?
(Estación Experimental Agropecuaria Balcarce, INTA, 2022-07)Nuevo récord mundial de embriones bovinos producidos in vitro promueve un giro hacia el uso de la criopreservación asociada al incremento sostenido en la producción de estos embriones. -
Recuperación de embriones en hembras de alpacas y llamas con ovulación única o múltiple
(Ediciones INTA, 2022-04)La capacidad reproductiva de los camélidos sudamericanos es baja, con un periodo de gestación de 11,5 meses y sufren pérdidas embrionarias tempranas, por lo que la búsqueda de técnicas exitosas para lograr reproducción ... -
RNA-seq analysis of single bovine blastocysts
(BMC, 2013-05)Background: Use of RNA-Seq presents unique benefits in terms of gene expression analysis because of its wide dynamic range and ability to identify functional sequence variants. This technology provides the opportunity to ... -
The effect of melatonin and season on in vivo embryo production of Dohne Merino ewes
(2014-07)To determine the effect of melatonin on embryo production in superovulated donor Dohne Merino ewes, two experiments were carried out at Trelew, Argentina (43° S 65° W), during the breeding and the anestrous seasons. ... -
Upregulation of interferon-alpha gene in bovine embryos produced in vitro in response to experimental infection with noncytophatic bovine-viral-diarrhea virus
(Springer, 2020-11)In-vitro fertilization is a routine livestock-breeding technique widely used around the world. Several studies have reported the interaction of bovine viral-diarrhea virus (BVDV) with gametes and in-vitro-produced (IVP) ...
