Can cloning be beneficial to us? Or is cloning a waste of time and dollars? Cloning as of recent years, has become a very controversial issue. Society is firmly divided on the uses and ethics of cloning. Cloning can range from copies of plants and animals to clones of humans and human organs. Should we clone humans and human organs?
Why clone human embryos? There are many legitimate reasons for investigating cloning. Embryologists believe that the research could help improve the lives of further generations. "Cancer research is possibly the most important reason for embryo cloning. Oncologists believe that embryonic study will advance the understanding of rapid growth of cancer cells. Cancer cells develop at approximately the same phenomenal rate as the embryonic cells do. By studying the embryonic cell growth, scientist may be able to determine how to stop it, and also stop cancer growth in return."
Another use for cloning is growing organs and / or tissues for humans. Cells can be manipulated to revert their embryonic stage and then these cells will have potential to grow into other tissues, cells, etc. This is done through chemical signals called fibroblast growth factors. These signals "tell" the cells what to do. These same chemical signals are also used on embryos. The fibroblast growth factors tell the cells what to become. Hans Spemann found the organizer effect, which is how the embryonic cells are aligned. The organizer effect shows that "the interior parts of it (the cell) tend to produce the parts of the head and the posterior parts of its parts of the tail (bottom)."
If cloning were allowed to be experimented scientists could use this process to clone exact replicas of a humans organ. This would prove very to be very beneficial to a person who may have lost a body organ such as a kidney, scientists could clone that particular organ for the individual, which, in the long run, would work better than a transplant organ.
Cloning would certainly expand the scope of medicine greatly, thus enhance the possibilities of conquering diseases such as the Parkinson's disease, cancer and other diseases that are considered incurable. Cloning can be used to produce vaccines and hormones, it already has led to the inexpensive production of insulin for diabetes and of growth hormones for children who do not produce enough hormones for normal growth. Monoclonal antibodies used the immune system to fight off disease could be injected into the blood system where it would seek out and attack a tracer element to the cloned antibody that would be able to locate hidden cancers in the body. They would attach cancer fighting drugs to the tracer and the treatment dose could be transported directly to the cancer cells (Clone...
