Development of an Interferon Bioassay and Primitive Endoderm Cell Lines to Study Lineage Specification During Early Bovine Embryogenesis
(Virginia Tech, 2015-01-09)
Embryonic wastage is rampant in cattle during early stages of pregnancy, particularly the first few weeks of gestation, a time recognized for significant remodeling of the embryo. Of particular interest to this laboratory ...
The Role of Nutrition and Administration of Estrogen in Holstein Calf Growth, Development, and Adenogenesis
(Virginia Tech, 2015-05-07)
Raising replacement heifers consumes a large portion of dairy and beef producers' income. An ultimate goal of producers is to decrease inputs and maximize outputs to produce fertile replacement heifers. Manipulating early ...
Post-Transfer Outcomes in Cultured Bovine Embryos Supplemented with Epidermal Growth Factor, Fibroblast Growth Factor 2, and Insulin-Like Growth Factor 1
(Virginia Tech, 2017-06-16)
The high incidence of pregnancy loss is a major issue facing the cattle industry. Use of in vitro fertilized (IVF) bovine embryos has become increasingly popular to help alleviate several of these reproductive issues and ...
Additive effects among uterine paracrine factors in promoting bovine trophoblast cell proliferation
(Virginia Tech, 2014-06-10)
Several uterine-derived paracrine factors have been implicated as critical regulators of conceptus development in cattle, but it remains unclear how these factors work together to establish and maintain pregnancies. The ...
Manipulating Embryonic Development and Endometrial Function in Ruminants
(Virginia Tech, 2018-04-13)
Early embryogenesis is highlighted by the emergence of several embryonic end extraembryonic lineages. One such lineage is the primitive endoderm, which will eventually give rise to the yolk sac. Once believed to be a ...
