Cloning could give hope to couples unable to have children of their own. By advocating cloning, doctors may find a way to cure or even prevent genetic diseases. Perhaps, though, the most important reason to advance cloning in the laboratory is to treat leukemia's and cancers. Very possibly, through cloning and genetic engineering, the growth of poorly formed cells could be stopped immediately. One reason to clone is hope for organ transplants.
Zanjani’s team hopes that the animal-human organs they are working on will have compatible new cells that are exactly the same as a patient’s organs for fixing damaged organs. With the new research they have found, it could be possible that they replace whole organs. The only problem about animal-human organs is that people could get viruses from animals that humans don’t normally acquire The original plan of Zanjani’s was to see prevent birth defects in unborn babies by injecting healthy stem cells into the fetus but in the process of doing this, he found that in doing this process, it could also be used to grow “humanized” organs. This idea came from the work of Flake. He found that the human cells develop into part of the heart, skin, muscle, fat, and other tissues when stem cells are taken out of bone marrow and injected into sheep fetuses.
After many successful cloning experiments on increasingly complex animals, scientists have begun thinking about human cloning. This has raised many debates about the ethics and safety of experimentally cloning humans. While some advantages could be gained from human cloning, it should not be performed due to significant medical, societal, and religious concerns. The most successful cloning results were produced using a procedure known as Somatic Cell Nuclear Transfer, or SCNT. SCNT cloning processes are performed by removing the nucleus with genetic material from an unfertilized egg, then replacing it with genetic material from the adult cell being cloned.
The birth of these transgenered animals provides a major stepping stone for the cloning of humans. Now groups say they are ready to clone a human being. Controversy over their plan runs high, but scientists believe the technology for human cloning, at least a limited type of cloning for now, is available. A revolution in reproductive biology is now taking place, that provides technical means for cloning humans. Many scientists who work with cloned animals say that the procedure is difficult and dangerous and too ethical to try on humans.
It is not the first time that cloning a mammal has been accomplished; however, it is the first time that a mammal has been cloned from an adult cell, not an embryonic one (Nash). The new cloning technique is raising many questions, the most controversial being the possibility of human cloning. Scientists say that, theoretically, the process used to clone Dolly would work for humans as well (Herbert). However, the cloning of humans should be regulated because of ethical, moral and religious issues. On March 4, 1997, President Clinton temporarily banned federally funded research for human cloning in the U.S., and gave the National Bioethics Advisory Commission 90 days to report on whether human cloning should be banned or regulated ("Clinton Bans.
The Benefits of Human Cloning This paper was written to show the reader with information on how cloning a human is a good idea. It may be too soon right now to clone a human, but in the near future scientists will be capable of cloning a human successfully. The rapid development of the technology for cloning has led to moral debates around the world on whether or not to ban cloning humans. With the advancement of clone technology two states, California and Michigan, have already banned the cloning of humans. "Everybody who thought it would proceed slowly and could be stopped was wrong," said Lee Silver, a professor from the University of Princeton.
These special type of cells can be a big impact on the human race and maybe even other races too, but to do that, we need to first research on them to acquire the knowledge we need to make a difference in this world. Embryonic stem cells are cells that come from embryos (eggs that have been fertilized in vitro) and these miraculous cells can become anything they want with the right DNA. The embryos are made in a specialized lab that are then donated for research, but they don’t come from a mother. Embryonic stem cells can do a lot of thing with lots of research including: can stop rejection of organs, can transfer into many stem cell lines, and can cure many diseases. Think of all the things one tiny discovery can do.
Usually scientists introduce the disease to the animals for testing. However, giving the animals the disease requires a lot of trial and error. Cloning could significantly diminish the time needed to create these animal models and the outcome would be a community of genetically identical animals. In addition, scientist can use cloning to make stem cells. Stem cells are the building blocks of the body that maintain and repair the body throughout ones life.
Scientists attempt to map out all the genes in the human genome, hoping the completion of the Project will bring great advances to medicine and biology. However, although genetic engineering of human and new technologies empower people such as the scientists and parents to bring them much benefits, genetics also create many ethical and social issues. Fist of all, germ line gene therapy brings up many ethical issues concerning the future generations. Gene therapy is generally accepted by the public. Somatic gene therapy only altars the genetic structure of an individual, therefore the gene will not be passed on to the children.
The two sides of human cloning is the side who believes that human cloning is morally, ethically, and religiously wrong and the side that believes that cloning could save countless lives and bring happiness to countless families. As a logical person I do see the possible benefits of human cloning but I believe that the results of cloning a single human would horrible disturb our already shaky way of life. The capabilities of cloning a human are endless and can help countless amounts of people. Human cloning can used to advance not only the life spans of patients, make new life, and advance the medical field. As stated earlier a clone of a person could be made and used as cattle for organs for the original.
