Influence of Growth Factors on Bovine Embryo Development
… to improve the in vitro production of cattle embryos by refining in vitro maturation (IVM) and culture systems. Cysteine supplementation to IVM media of bovine oocytes increases cellular glutathione production, which reduces reactive oxygen species (ROS). Similarly, beneficial effects of …

Effect of immunoglobulins on early bovine embryo development in vitro
Bovine morulae (day 6: n=257) were obtained to evaluate the [effect of immunoglobulins (Ig) on early bovine embryo development in vitro. Fifty-four cows superovulations were conducted in 36 cows with follicle stimulating hormone. Embryos were collected by non-surgical procedures and morphologically …

The effect of uterine flushings on early bovine embryo development in vitro
Bovine morulae (day 6; n=328) were obtained to evaluate the effect of uterine flushings (UF) obtained from ovariectomized progesterone (P) or estrogen (E) treated cows or from previously superovulated cows on day 6, 10, or 15 post insemination on early embryo development. Ninety-eight cows were …

Determining the Effects of Nerve Growth Factor Supplemented In-vitro Fertilization Media on Bovine Embryo Development
… as a large source of oocytes for creating IVP bovine embryos. These techniques have allowed for more efficient dissemination of valuable female genetics compared to traditional artificial insemination or embryo flushing. IVP embryos have lower embryo development rates and quality, leading to …

The effect of steer serum, bovine serum albumin and uterine flushings from ovariectomized progesterone-estrogen treated cows on early bovine embryo development
… superovulated with follicle stimulating hormone. Embryos were non-surgically recovered 6 days post-mating. Ninety embryos were morphologically evaluated and placed in culture in Hams F-10 media supplemented with a 10% protein source (steer serum, bovine serum albumin, or uterine flushings). Embryo …

Characterization of Maternal Factor MOF/H4K16ac and the Impact of the Cryostress on Bovine Embryonic Development
Precise gene regulation is critical for mammalian embryo viability. Bovine embryos, which share high transcriptomic similarity with humans, serve as valuable models for understanding fundamental biological processes. Insights gained from studying bovine embryogenesis can transduce to broader …

Effects of culture conditions on development of early murine and bovine embryos
Early mouse (n = 501) and bovine (d = 6; n = 172) embryos were obtained to evaluate the effect of a deproteinized hemodialysate (CLBl 107) on embryo development in vitro. Bovine morulae also were cultured to examine the effect of agar embedding and the environment of immature mouse uteri on embryo …

Supplementing Bovine Embryo Culture Media to Improve the Production and Quality of In Vitro Produced Bovine Embryos
… inhibitory factor (LIF) in preimplantation bovine embryos. Neither cytokine affected the total percentage of embryos which developed to the blastocyst stage in vitro. However, supplementation of IL6 increased blastocyst inner cell mass (ICM) cell number without affecting trophectoderm (TE) …

Post-Transfer Outcomes in Cultured Bovine Embryos Supplemented with Epidermal Growth Factor, Fibroblast Growth Factor 2, and Insulin-Like Growth Factor 1
… industry. Use of in vitro fertilized (IVF) bovine embryos has become increasingly popular to help alleviate several of these reproductive issues and provide a means to enhance genetic gain for production traits. An uterine paracrine factor cocktail containing epidermal growth factor (EGF), …

Additive effects among uterine paracrine factors in promoting bovine trophoblast cell proliferation
… implicated as critical regulators of conceptus development in cattle, but it remains unclear how these factors work together to establish and maintain pregnancies. The primary objectives of this work were to establish if cooperative interactions between epidermal growth factor (EGF), fibroblast …

The Role of Amino Acids and the Threonine-SAM Pathway in the Development of Bovine Inner Cell Mass and Pluripotency
… cell mass (ICM) of preimplantation mouse and rat embryos, known as embryonic pluripotent stem cells (ePSCs) or embryonic stem cells (ESCs) or via reprogramming of somatic cells to their pluripotent state, known as induced pluripotent stem cells (iPSCs). PSCs are excellent tools for gene editing …
