Supporters of cloning feel that with the careful continuation of research, the technological benefits of cloning clearly outweigh the possible social consequences. In their minds, final products of cloning, like farm animals, and laboratory mice will not be the most important achievement. The applications of cloning they envision are not nightmarish and inhumane, but will improve the overall quality of science and life. Cloning will help to produce discoveries that will effect the study of genetics, cell development, human growth, and obstetrics. Human cloning is not the issue, it is merely a threat to the continuation of cloning research. Their arguments for such research are displayed here.
Cloning might produce a greater understanding of the cause of miscarriages, which might lead to a treatment to prevent spontaneous abortions. This would help women who can't bring a fetus to term. It might lead to an understanding of the way a morula (mass of cells developed from a blastula) attaches itself to the uterine wall. This might generate new and successful contraceptives.
Cloning experiments may add to the understanding of genetics and lead to the creation of animal organs that an be easily accepted by humans. This would supply limitless organs to those in need. The growth of the human morula is similar to the growth at which cancer cells propagate. If information derived from cloning research allows scientists to stop the division of the human ovum, a technique for terminating cancer may be found.
Cloning could also be used for parents who risk passing a defect to a child. A fertilized ovum could be cloned, and the duplicate tested for disease and disorder. If the clone was free from defects, then other would be as well. The latter could be implanted in the womb.
Damage to the nervous system could treated through cloning. Damaged adult nerve tissue does not regenerate on its own. However, stem cells might be able to repair the damaged tissue. Because of the large number of cells required, human embryo cloning would be required.
In in-vitro fertilization, a doctor often implants many fertilized ova into a woman's uterus and counts on one resulting in pregnancy. However, some women can only supply one egg. Through cloning, that egg could be divided into eight zygotes for implanting. The chances of pregnancy would be much greater.
Cloning would allow a women to have one set of identical twins instead of going through two pregnancies. The women may not want to disrupt her career, or would prefer to only have one pregnancy. With cloning it would be assured that they would be identical.
Cloning could provide spare parts. Fertilized ova could be cloned into several zygotes, one would be implanted and the others would be frozen for future use. In the event the child required a transplant, another zygote could be implanted, matured, and eventually contribute to the transplant. Some believe that if a parent wanted to produce talents in a child similar to his own, cloning using DNAfrom the cell of the adult may produce a child with the same traits. Many are skeptical about this possibility.
