Interspecies embryo transfer in animals has been used for agricultural, conservation, and basic scientific purposes. At least 24 different combinations of taxa have been involved in intertaxon embryo transfer. Although relatively little is known about the mechanisms that control compatibility between ...
the union of thespermwith theovumresults in a zygote, or fertilized egg, which begins a rapid series of cell divisions called cleavage, or segmentation (seemitosis). Each kind of organism has its own characteristic sequence of development, and related species usually have similar developmental patt...
Embryo Transfer has been used in many domesticated species to improve production and performance by increasing selection intensity of the desired trait. In the dromedary camel this has occurred almost exclusively in the racing camels of the United Arab Emirates. The technique is particularly useful in...
An organism in its earliest stages of development, especially before it has reached a stage at which it can be distinguished from other species. The human embryo is so called up to the eighth week after fertilization. After that it is called a fetus. ...
The physiological mechanisms that lead to the requirement for synchronous embryo transfer have been defined in some species, particularly the sheep. In mat... I Wilmut,DI Sales,CJ Ashworth - 《Theriogenology》 被引量: 171发表: 1985年 Reproductive Technologies in Farm Animals Embryo transfer, in ...
Embryo production and possible species preservation by nuclear transfer of somatic cells isolated from bovine semen. Theriogenology 74, 1629-1635.Liu J, Westhusin M, Long C, Johnson G, Burghardt R, et al. (2010) Embryo production and possible species preservation by nuclear transfer of somatic ...

Oral transfer of adult Ancylostoma ceylanicum hookworms into permissive and nonpermissive host species Weanling hamsters given an oral AWT of 40 or 60 mixed-sex A. ceylanicum worms rapidly developed anemia; in the higher-dose group, hemoglobin levels ... RD Bungiro,BR Anderson,C Michael 被...
while we assessed mutagenesis efficiency at the whole-embryo level before single-cell sequencing, low levels of mosaicism in F0 crispants are a concern, especially when this approach is used for morphogens or other secreted factors where a small amount of mosaicism may be sufficient to rescue a ...
These species are still used as models for the development and refinement of many of the systems used in human ART procedures. In most species studied, researchers observed that the embryos arrested at specific stages of preimplantation development in vitro. The developmental blocks and retardation ...
