Let us come to the what is trending today.
The day before, China Academy announced: the world's first cloned monkey in individual cells China birth. When people are excited, they also have a hidden fear: will one day be cloned, too? Will the success of primate cell cloning bring more ethical dilemmas to human beings? The scene in Hollywood's 2005 sci-fi blockbuster "escape the island of clones" seems no longer a science fiction.
In fact, from the day of Dolly sheep's birth, or even earlier, people have realized that cloning is no longer a theoretical problem, and the success of technology is sooner or later. Therefore, ethical discussion on cloning technology has never ceased. In 2000, the first embryonic cell clone of Macaca mulatta was born in the United States, and it has been widely discussed in the world.
However, in the view of most scientists, it is not only an ethical problem, but a law that can not be violated. Not only the cloning technology, 20 years, the rapid development of life science and technology, gene editing, transgenic technology, scientists and religious circles, the public have been discussing the ethical issues which may involve and cause, and gradually in a wider range and trend reached theunanimous. Since then, various countries have introduced relevant laws and regulations to conduct ethical norms on the use and research of many technologies, including cloning technology. For example, the ethical guidelines for human embryonic stem cell research, published in 2003, clearly stipulate that any research on reproductive cloning is prohibited.
The results of cloned back somatic cell cloned monkeys. According to the introduction, the experiment was carried out under strict ethical norms. In early 2005, China Neuroscience Research Institute of Shanghai Academy of Sciences China Life Science Research Institute, established by the Scientific Committee on ethics ethics expert, biology experts, medical experts and members of the community life, "guide to Shanghai life science researchers and relevant project in life science research involving human and animal ethical and procedural issues and help", "carry out the ethical review management, basic standards of life science research project of ethical review, life science research on plan involving the human body and animal's prior review, approval of projects in line with the standards of ethics, and to study the approved for monitoring, to ensure that the object has been research involving protection, for all research projects contrary to the ethical norms of veto Or require an amendment to the misconduct. The experiment of somatic cell cloned monkeys was also carried out under the review and supervision of the ethics committee.
So, does the use of primates violate the ethics of scientific research, especially the principle of protecting animal life as far as possible? There is no consistent answer to this question. However, as the China Neuroscience Research Institute, Academy of Sciences Academician Pu Muming, the United States, Britain, Germany, Japan and other countries every year with a lot of monkeys for drug screening and other scientific research, but because of the different genetic background of the macaques, need a large number of animal experiments can effectively screen. With somatic cloned monkey technology, it will be able to produce model animals with the same genetic background, which will reduce the number of experimental macaques.
Of course, the ethical issues involved in the survival and development of human beings, and how to be prudent, need to be involved and fully discussed, including the scientific and technological community. However, technology itself is not good or bad, the key lies in the people who use them - the man who can threaten the human existence is never the technology, but the human itself.
