Egg cell development into unfertilized single embryonic human sexual reproduction
Has nurtured the clone sheep Dolly United Kingdom research institutions 8, reported that their first sexual reproduction through sin, so that the human egg cell in unfertilized cases in embryo development adult classes.
This technology is not a clone. Korea and the United Kingdom scientists previously cloned human embryos, is the nucleus of the removal of eggs, implantation of somatic cell nucleus. While Roslin Institute scientists do not use exotic genetic material, only eggs to produce embryos.
8, Roslyn Institute scientists in Scotland in the capital Dublin Ireland United Kingdom Scientific Association section on reported that they accept the many women in surgery out 300 eggs, cultivation in the lab. Which half egg survival success, only 5% growth for the early embryo — the blastocyst. Oocyte and sperm into the genetic material and half only somatic chromosomes, scientists through a special technology makes these eggs in development into a blastocyst ago obtained sufficient genetic material.
Researchers say they do this research aims to obtain human embryonic stem cells, and present results to achieve this. They say that this way of embryonic stem cells will be directly used for human transplantation. Embryonic stem cells can differentiate into a variety of human cells "universal cell", scientists currently exploring how to use this kind of cell cultivation of different body organs, to replace the diseased organs in patients.
Scientists say that the current technology can only contribute to spawn a single sexual reproduction develop into embryos, they will attempt to use the genetic material of the sperm to cultivate embryos.
