"Half-Blood Beast" behind: the destruction of human progress or
Author: Source: Beijing Science and Technology News Release: January 2, 2009
In the past few years, American scientists of human stem cells into the embryos of many animals, "cooked up a secret" a lot of experimental "He Maila mixed" products, such as pigs with human blood stream of "man-pig He Maila ", the sheep's liver in the body composition of 80% belong to the human liver" He Maila sheep, "added skulls mice's brain cells" He Maila rat. "

At the beginning of all things, the name does not, nor is there a standard form, the dog will be called as a dog, the dog became dogs, pigs will be called into a pig, so that it becomes like pig ... ... Some people say that God created the All things, it was said to be the human form fabrication Nu Wa, but the more people believe that it is all but inevitable that a coincidental.

Such information so that some people are "chilling" and imagination: "When the people of the organ in the body of the animal growth, with human or pig cells in mice, would not be the same as human thought, and has to act like animals?" Asserted: "They brought the fear of human society, has long gone beyond the limits of human knowledge and human science of the space accept."

Daihatsu and then start the anti-science platitudes such as "science is not God, should not be a substitute for natural biological selection is the key to the" (it seems to engage in human years on the breeding of animals and plants --- --- artificial selection are the Prohibition), "even if GM and the restructuring of individual life can not be entirely human as the basic utilitarian purpose, it must adapt to the life of the development of the laws of nature" (a biologist, I am afraid not know "the development of the life of the laws of nature "What specific means of what is, how to adapt to?), And even predicted:" Today, if the curse in the name of scientific development so as to create a 'He Maila', in addition to the human waiting for the legendary killed Mehmet Latin America's Heroes Baileluofeng come, but also to wait for what? "The really scary.

The reason for this panic, in part because the compiler was attributed to mystify. These experiments are open experiment, "Washington Post" in the original text did not "secret", but described by those who compiled on a "secret concoction", as if people can not see what is the secret experiments like. These experiments will compile the product known as "He Maila," This is an English transliteration of the chimera aliasing, who is more accurate Chimera, is the ancient Greek mythology as a predecessor of the Lions, as the central goats, like back The monster snake spit fire. This story is also easy to have a terrorist associations, think of the "" Book of Mountains and Seas, "in which different patterns of the monster," Resident Evil "are endowed with aggressive man-made monster is not distant."

Chimera, or chimera is nothing new, nor is it anything bugbear

In fact, "Chimera" biology is a very commonly used term is also very common in the natural biological phenomenon. "Chimera" the general intention to "chimera", referring to the individuals from different biological molecules, cells or tissues to be combined together into an organism. Twins in the same development in the womb when the exchange took place cells, most of the twins in the body are carrying some of their compatriots from the cells, they are chimera. In the course of fetal development, maternal and fetal cells in the exchange will occur, the majority of mothers carrying the body for life gave birth to their children some of the cells, many people are carrying the body of their mother, some of the cells, these mothers, children Chimeras are. Those who receive an organ, but also all chimera.

Different species can also form a chimera. For example, the two dissimilar from animal embryos embedded a synthetic embryo can dissimilar chimerism breed animals, like sheep - goat chimera, MA - Zebra chimera, and so have been successful cultivation. Many patients with heart transplant a pig or cow valves, they are dissimilar chimera. Recombinant DNA technology, transgenic technology is also a matter of fact in the molecular level to create the mosaic.

Chimera chimera, or so it is not unusual, nor is it what the scary thing. The human brain is the organ of thinking, the animals grow human heart, liver, the organ and the like, will not let any of these animals have on the human ability to think and put forward as "human organs in the body of the animal growth, with Pig or human cells in mice, would not be the same as human thought, and are acting like animals "such a doubt, it is useful to think of the brain to replace the heart of the suspects.

David Waisman Laboratory at Stanford University recently injected into fetal mouse neural stem cells in some people, to create the mouse brain cells, about 1% of the well-doping brain cells. But the human brain is a highly complex structure, just head to the other animals into a number of human brain cells, and these will not head into the human brain and has the ability to think. Weismann after the idea of the possibility of the brain to create all the components of human brain cells in mice, this mouse has been such a really long the human brain, will it follow the thinking of people as possible, which can The ethical issues. But at the moment this is only a think about it "experimental thinking" and did not become a reality, it is unlikely to become reality. Animal chimera of great value in scientific research and medical value

Scientists have long to create such a human organ Chimeric animal is not left Emily to create a monster. They have a great scientific value and medical value. For example, Weismann in the experiment, the human neural stem cells injected into fetal mice, and then on different developmental stages of the chimera of the fetal rat brain autopsy to know the process of embryonic development in human brain cells is how to migrate, thus Help our understanding of the human brain development. HIV infection can not be mice, mice can not be used as a model for AIDS research animals. But if we try to let some long-mouse's immune system, HIV can be infected with the chimeric mice, which has now been used to test the treatment of AIDS drugs. Long a human organ Chimeric animals may be used after organ transplants.
