To further understand the events occurring during embryogenesis, it is imperative to have an experimental system. While somatic embryo is the system of choice due to the prolific number and success of protocols available, it is necessary to compare in vitro results with those in vivo.

AbstractThe three methods of culturing bovine zygotes; surrogate oviducts, co‐culture and defined media are compared and contrasted. Surrogate oviducts provide the best environment and so provide a benchmark to compare in vitro culture systems. At present, co‐culture systems provide a convenient method of reliably producing embryos suitable for ...

A large contributor to success during in vitro fertilization (IVF) lies in the processes occurring within the IVF laboratory. These processes make up the "culture system." This system entails numerous procedures and technical steps that must be optimized to produce a competent embryo.

The direct effects of chemical exposures, environmental extremes, and nutrient quality/quantity have been very difficult to study in mammalian embryos due to their anatomical inaccessibility, paucity of tissues, and other factors such as real ethical concerns in human studies.

Many variables must be considered when choosing a clinical culture system. Although animal studies provide a strong evidence-based profile as to the composition of viable clinical systems, the true test of efficacy in a clinical setting is to test the system within one’s own laboratory by randomizing sibling oocytes or embryos to the test system or the

The rabbit is a mainstay of regulatory developmental toxicity testing; however, due to the historic absence of experimental tools for this species, there is a dearth of information about its fundamental embryology and the mechanisms underlying developmental toxicity.

Culture Systems: Embryo Density
2012Embryo density is defined as the embryo-to-volume ratio achieved during in vitro culture; in other words, it is the number of embryos in a defined volume of culture medium. The same density can be achieved by manipulating either the number of embryos in a given volume of medium, or manipulating the volume of the medium for a given number of embryos ...

The zygote (fertilized egg), through a series of well-defined developmental stages, forms an embryo (Fig. 11.1), the progenitor of the next generation. Several physical and chemical factors regulate the growth and development of the embryo. The surrounding tissues, especially the endosperm, also control the predetermined pattern of embryo development ...

The direct effects of chemical exposures, environmental extremes, and nutrient quality/quantity have been very difficult to study in mammalian embryos due to their anatomical inaccessibility, paucity of tissue, and other factors that make human studies unethical. Many acute and chronic developmental anomalies can trace their origins to postimplantation
