Growth, development, and gene expression by in vivo‐ and in vitro‐produced day 7 and 16 bovine embryos
The effects of the embryo production system on growth and transcription rate of day 7 and 16 bovine embryos were investigated. In vivo‐ (controls) and in vitro‐produced (IVP) embryos were transferredExpand

Morphology and morphometry of in vivo- and in vitro-produced bovine concepti from early pregnancy to term and association with high birth weights.
This study was designed to characterize conceptus development based on pre- and postnatal measurements of in vivo- and in vitro-derived bovine pregnancies. In vivo-produced embryos were obtainedExpand

Hot topic: using a stearoyl-CoA desaturase transgene to alter milk fatty acid composition.
Stearoyl-CoA desaturase enzyme converts specific medium- and long-chain saturated fatty acids to their monounsaturated form. Transgenic goats expressing a bovine beta-lactoglobulin promoter-ratExpand

Evidence of increased substrate availability to in vitro-derived bovine foetuses and association with accelerated conceptus growth.
Changes in placental development have been associated with foetal abnormalities after in vitro embryo manipulations. This study was designed to investigate bovine conceptus development and substrateExpand

Increased Efficiency of Transgenic Livestock Production
Production of transgenic livestock by pronuclear microinjection of DNA into fertilized zygotes suffers from the compounded inefficiencies of low embryo survival and low integration frequencies of theExpand

Measures of maternal-fetal interaction in day-30 bovine pregnancies derived from nuclear transfer.
Embryonic mortality and abnormal placental morphology have been reported by most researchers studying nuclear transfer (NT), and it now is accepted that placental anomalies and poor development ofExpand

Perinatal physiology in cloned and normal calves: hematologic and biochemical profiles.
Although a majority of clones are born normal and apparently healthy, mortality rates of nearly 30% are described in many reports. Such losses are a major limitation of cloning technology andExpand

Effect of the nuclear-donor cell lineage, type, and cell donor on development of somatic cell nuclear transfer embryos in cattle.
Potential applications of somatic cell nuclear transfer to agriculture and medicine are currently constrained by low efficiency and high rates of embryonic, fetal, and neonatal loss. Nuclear transferExpand

Attempts to enhance production of porcine chimeras from embryonic germ cells and preimplantation embryos.
Porcine embryonic germ (EG) cells share common features with porcine embryonic stem (ES) cells, including morphology, alkaline phosphatase activity and capacity for in vitro differentiation. PorcineExpand

Progestin implants can rescue demi-embryo pregnancies in goats: a case study.
Survival after transfer of demi-embryos (i.e., half-embryos produced by embryo splitting) to recipients usually is lower than survival after transfer of intact embryos. Reduced survival afterExpand
