Scientists do headless animal experiments can manufacturing headless (map)

1928 Morgan confirmed the chromosomes are the carriers of genetic gene, which won the Nobel Prize in Physiology or medicine
Homeobox genes homologous is 1984 in Drosophila body discovered

Double chest mutant fruit flies, the result would have been long 2-wings of Drosophila born out of the four wings

Normal the tentacles of Drosophila melanogaster tentacles of mutations to foot

"Scientists have proved that they can remove the embryo development of gene control head, in the lab to create a ' headless rats '. Science and medicine, one of the last goal is to live forever, I worry about the ' Headless ' experiment is a laboratory of secret plans. Scientists can create no brain and thought ' Headless ', but his body all part can be used for normal organ transplantation. "This is the India medical experts p.b. Desai at the recent world of a surgeon's speech at the meeting.  Does anyone in processing no brain and mind, but the body of the function is completely normal "headless"? Desai of worry is not groundless? headless animal experiments, undoubtedly opened the "pandoras box." According to the United States the world net daily and the India Stan times recently reported that in India Delhi a world surgeons meeting, India medical experts p.b. Desai in a field named "conquer death" speech to from around the world in more than 250 medical experts warn: the 20 th century, the United States University of Texas in the lab scientists have created a "headless rats" mouse brain, but no other body part is still alive.  Desai, worry, some scientists are likely to walk out of the scariest but also exciting next step — produced in the lab "headless"! Desai's speech was published, some of the tabloid reporters love me be rendering in a big way, and nose have eyes to distribute the so-called "explosive" News: scientists have developed several headless animals, in a mysterious Labs, there are 10 headless human embryos is pregnant, and 2 No baby was born in June in the secret, but because no head baby breath, the mortality after birth. Reporters also allocates a blurry photo, no head baby suspended in formalin solution, the "face" detestable. Insiders at a glance, this picture is fake! true or false, the United States scientists concoct a without head animal experiments, undoubtedly opened the "pandoras box", and some scientists of panic — because they believe that the mankind on the extension of the life of an urgent request, will result in a "headless" natural experiment was born.  According to introduction, Desai "headless" is more of a person, rather than a no brain and the body of thought, but "he" in the body including the heart, the lungs of various organs and ordinary people no different, "he" just missing the head and the brain, without any thought of operation.  In fact, no creature is not what the "explosive" news. Early in October 1997, the United Kingdom Paz University announced that produce no head frog embryos, prior to this, the media and headless cultivate successful reports. Just, flies and frogs are mammals, and the mouse and human genes are similar, and is a member of the mammalian family, nurturing "headless rats" of concern are reasonable. Then, head of animal breeding and how?

United States biologist Edward · Lewis to find out what the biological body structure and the relationship between genes, decades of study, certified organism from a single fertilized cell begins to become contains millions of specialized cells in the body of a frog from the flies, to human animals have almost the same set of genes. This gene is the blueprint for the animal species, the architect of the exercise of a main control functions to guide the growth and development of animals. In the embryonic growth process, each cell in a variety of genes on and off causing cells of special features.  For example, produce eye lens protein genes, just in the formation of the cells in the eye are active, and the creation of toenails protein gene, even if they appear in the same cells, but they can not be expressed. The small number of these genes, but have changeable properties. Because of their mutation, some parts of the organism misplaced. For example, in a study of the Drosophila melanogaster, control found in Drosophila melanogaster long tentacles of the gene mutates, Drosophila of forelimb may grow to be born horn parts. To control chest of gene mutation has occurred, the chest 3 section into long wings 2nd section, with the result that would have been long 2-wings of Drosophila was born out of the four wings. This control biological body structure of the gene, called by Lewis Homeobox Gene "con."  Homeobox genes are homogenous in 1984 was discovered, scientists will this finding fame as "biology a landmark milestone."  "Homologous Homeobox gene mutation," scientists in the laboratory simulation of the biological evolution of the phenomenon. Homologous gene mutations in a Homeobox began early in the embryonic when changes are not great, but with the Organization, the organ of the effect of stereotypes, mutations to be amplified, causing the body structure of significant change. Developmental biology of these discoveries, and even the scientists can in the laboratory simulation of biological evolutionary phenomenon. huge For example, in 1995, a laboratory of the University of Geneva to zebrafish homologous Homeobox Gene expression in slow, found in embryonic development, fish fin cell layer stacked into bone, last long out of the toes.  This allows scientists to understand how evolution fins into four limbs. According to the United States Desai describes, researchers at the University of Texas mouse embryo found control embryonic grow head of genes, they apply these genes from mouse embryonic removal and treatment of more than 1000 mouse embryonic implantation mouse uterus, last four "headless rats" students. In the absence of the head and the respiratory system, these "headless rats" immediately died.

Some scientists think that the "headless" can become a "human body parts factory." By cultivating "headless rats", people think of training "headless". We know that, despite the organ transplant to save people's lives has high, but the biggest problem is the lack of donor. There is information indicating that the donor and waiting for organ transplantation receptor ratio is 1: 10, tens, hundreds of thousands of patients waiting for organ transplants. United States Princeton biologist Lee · Sylvie in United Kingdom the Sunday Times reporter said: "through the ' headless rats ' technology, scientists can produce a head or brain ' Headless '. This does not have any awareness of the human body may not be regarded as a person, so scientists can legitimately let them survive, as a future rich sources of organ transplantation. ”

Biology Professor Louis, University of London · volpert, "headless" for organ transplantation has opened up a broader space. "Headless" heart beating, so the organs of the blood supply is maintained, the organ tissue will not occur as deaths, hypoxia ischemia. As an organ donor, these organizations have the stronger vitality, as a prerequisite for successful transplantation provides. If the headless organ can replace human organs function properly, you can build a lot of "human body parts factory", the mass production of headless. In this way, those who need a transplant patient will never die while waiting. Although in laboratories manufacturing "headless" let people feel disgusted, but if you lack the human organ transplant, and "really headless" again to save many lives, "headless" experiment may be reluctant to accept.  Volpert recognizes that human beings should be cautious in using this new technology to the benefit of mankind and not a disaster.  Experts believe that in the current technical conditions is not possible to produce a "headless". Although the "headless" can become an organ transplant "Po ore", but no doubt it will be thrown and the cloning of human beings equally fierce ethics dispute storm. Because the technology if the out of control, will be a black hole of organ transplantation and organ traffickers ' horrible tool.  Even if the "headless" experiment because the law prohibits the ethical reason subjected, but as a "headless" technology has broad organ transplant Business Outlook and therefore do not exclude some maniac in order to profit from consenting experiment may, this is a modern science must face one of the many ethical challenges. Worthy opponents can rest assured that most experts believe that mammalian embryo culture extreme difficulties, is not considered ethical factors, in the current technical conditions is not possible to produce a "headless" impossible "headless" applications in human organs.
