In Britain, the first license to create human embryos chimeras exhibited

British agency on artificial fertilization and embryology has granted the first license for embryos to produce chimeras, both human and animal genes. You have two groups of researchers from King's College London and the University of Newcastle. Cows or pigs - In June last year, the Commission on Ethics of the British Academy of Medical Sciences recognized the ethical acceptability of the use of hybrid embryos by introducing nuclei of human cells into animal eggs. These embryos can be an alternative source of embryonic stem cells, so close in its properties to be human. Want to use scientists from King's College London, the cells in chimeric embryos develop experimental treatments for Alzheimer's, Parkinson's and other diseases of the nervous system. Researchers from Newcastle examine learn the processes of differentiation of stem cells into cells of various tissues, such as to reproduce this process in the laboratory. Using chimeric embryos allow scientists to them in the uterus of an animal or human implant, but they also need the latest on 14 Days of development may be destroyed.
