What Is an Embryo Transfer?
Embryo transfer, also known as fertilized egg transfer, refers to the technique of transferring the early embryos of female animals, or embryos obtained through in vitro fertilization and other methods, to female animals to continue to develop into new individuals.
Embryo Transfer
- Embryo transfer, also known as fertilized egg transfer, refers to the transfer of
- The first embryo transfer in the world was done by British W. Ship in 1890,
- Embryo segmentation
- The main instruments required for embryo segmentation are solid microscopes and micromanipulators.
- During embryo segmentation, a well-developed mulberry embryo or blastocyst should be selected and divided with a segmentation needle or knife. When segmenting a blastocyst, care should be taken to divide the inner cell cluster equally, otherwise it will affect the embryo's recovery and further development. .
- Embryo segmentation is mainly used for the breeding of excellent breeds. Take cattle as an example, some milk is more, but reproduction is slow. At this time, the bred cow was ovulated with gonadotropins, and then the eggs were taken out of the cow, and in vitro fertilization was performed in a test tube with artificially collected sperm to cultivate an embryo, and the embryo was then passed through During the same period of hormone treatment, can accept embryos, the uterus of the same cow during pregnancy, gave birth to calves.
- Although embryo segmentation technology has been successful in a variety of animals, there are still some problems, such as the low weight of newborn animals, and differences in hair color and markings. Practice has proved that the possibility of using embryo segmentation technology to produce identical multiple embryos is limited. So far, the most common are identical identical twins, and the proportion of identical multiple births is very small.
