United Kingdom will approve the cultivation of human and animal hybrid embryos (photos) _ pet baby

Human stem cells and animal embryos resulting from the combination of new species in the world led to widespread controversy.
Times appear according to the China daily reports that the United Kingdom concerned will be announced on 5 September, approved the scientists are human and animal cells mixed up and used in the manufacture of fetal medicine research plan, and the United Kingdom poll results show that most people to cultivate "human responses in hybrid" embryos. Most people support United Kingdom artificial insemination and Embryology Authority (HFEA) conducted this survey to spend $ 15 million pounds (about RMB 227.5 million), which lasted three months. It was alleged that the investigating officers "to provide further information and informative discussions, the majority of people on the project approach easy." United Kingdom Royal Society President Martin · Reese said: "the HFEA's survey, the number of people on this research welcomed the potential value, 61% of respondents indicated that if this study can help scientists better understand the disease, they agreed to manufacture human and animal hybrid embryos, only 1/4 of people opposed to this study. "Which, on the manufacturing of human egg cells and embryos of hybrid animals that support more, but for other types of hybrid embryos less support, such as the use of animals and human egg, sperm manufacture hybrid embryos. Scientists apply according to the United Kingdom media, November 6, from Newcastle University and the London Kings College for two research groups to apply for the first time to the HFEA, wishes to human and animal cells mixed up manufacturing embryos for medical research. Their plan is from the particular patient's skin cells in the cell nucleus, implantation deletion of nuclei of cattle or rabbit egg cell, create a hybrid embryo cells. The scientists said that once the embryonic cells mixed success, they will extract the stem cells, then the destruction of embryonic cells immediately, never allow it to survive for more than 14 days. It is learnt that the extract from the embryo without full development of stem cells, can produce various human tissues, is used to treat leukemia, Parkinson 's, Alzheimer's disease, heart disease and organ failure, and other diseases. As with cell providers own gene characteristics, so a patient transplantation will not produce Allograft Rejection, with very high medical value. Throws a "half-orc" dispute against and some religious organizations stated that the study may subvert human and animals. There are also some ethics experts said the offensive, it sounds like the craziest of Arabian nights. Last December, the United Kingdom Government issued a white paper, expressed plans to prohibit use of animal cells cloned human embryos as "quite a lot of the public may create mixed with animal and human genetic material of embryonic nervous." But only 5 months after authorities "let go". In theory, this "hybrid embryos" can be implanted into the uterus in pregnant women, and eventually gave birth to an owner and animal genes "investigation of hybrid creature." But this kind of "chimera (guest Myra)" but also lead to many difficult ethical issues. At present the problem in many national laws are blank. Li Hui keywords: "chimera (guest Myra)"
"Chimera (guest Myra)" is a myth in Greece by reference to HSBC 100 head monster (father) and the Echidna de (mother) hybrid born offspring. "Chimera (guest Myra)" is a myth in Greece only lion's head, sheep body and tail of a snake spit fire monster, is a reference to HSBC 100 head monster (father) and Echidna de man (mother) hybrid offspring. It extended to the medical field, it is the investigation of hybrid embryos "grow up" after the image of the rooster. Over the years, with the escalating medical technology, scientists have successfully put human cloning to bacteria and animals. In 2003, Shanghai second Medical University researchers will human skin cells and Bunny egg cell fusion, nurturing human embryonic stem cells. The study of embryos, be United States technology media as the first cases successfully manufactured investigation of hybrid "guest,". In 2004, the United States, Minnesota, of the Mayo Medical Center's Jeffrey · Platte doctors by human stem cells into the pig embryos to produce some of the "pig", guests, these pigs will stream the pig blood, also with blood. In another experiment, the University of Nevada, United States of Ismail and Zanjani, scientists will be moved into human stem cells from embryos, sheep produce a number of "guest Myra sheep". These "mestizo sheep" liver approximately 80% of the cells is the human stem cells.
