On July 5, 1996, Dolly, a domestic sheep, was born at the Roslin Institute, a research center in Scotland. The birth, however, was far from normal. Dolly had been produced by cloning methods and was born to a surrogate mother (“Cloning Fact Sheet”). The methods used to clone Dolly were once considered to be biologically impossible (Wilmut and Highfield 12). Thus, once Dolly’s birth was announced to the rest of the world, an immediate debate over the ethics of cloning began. In particular, reproductive cloning was widely discussed because it could possibly be accomplished through somatic cell nuclear transfer to clone entire humans (“Cloning Fact Sheet”). For medical, social, religious, and political reasons, there are both proponents and opponents of reproductive human cloning and its ethics. Currently, the best way to deal with reproductive cloning is to ban its use because there are many negative consequences that could arise from using cloning technology. There are two different types of human cloning: therapeutic cloning and reproductive cloning. The goal of the former is to obtain stem cells from embryos that can be used to study the growth of the human body and to find possible cures and treatments for various diseases (“Cloning Fact Sheet”). The purpose of the latter, on the other hand, is to create a whole human being through cloning. Specifically, reproductive cloning is done using somatic cell nuclear transfer and can theoretically produce a human that has the same exact nuclear DNA as another individual. Currently, though, this technology has only been used to clone animals and has not yet been successful in cloning humans (“Cloning Fact Sheet”). The process constituting somatic cell nuclear transfer begins with the extraction of nuclear genetic material from the cell of an adult donor. Then an egg is deprived of its nucleus, and the DNA taken from the donor cell is placed into the egg. Afterwards, the egg is stimulated by either electric current or chemicals so that it will start dividing into more cells. Eventually, an embryo forms from the cell division, and this embryo is implanted in a host uterus, where it develops until birth (Morris). The arguments for and against reproductive cloning are diversified. There are more people who oppose this form of cloning than those who support it because of the unknown implications of cloning in general (Morris). Even when applied only to animals, the technology for reproductive cloning is still immature. Nevertheless, proponents of reproductive cloning claim that reproductive cloning should be permitted due to a wide variety of reasons. One of these is freedom of choice, which supporters argue should not be taken away from those who want to procreate by methods of cloning. Persons who might want to procreate via cloning include same-sex couples and persons with infertility (Morris). Another common argument is that the process of cloning entire humans can provide insight into how certain genetic diseases can be cured (Morris). In addition, clones could be used as replacements for lost family members, and they could be used as replicas of persons with high intellectual ability or social status, like science geniuses and celebrities (Wilmut and Highfield 36). Opponents of reproductive human cloning base part of their argument on the low success rate of animal cloning. On average, the success rate for somatic cell nuclear transfer is between a low of 0.1 percent and a high of 3 percent, and critics point out that human cloning may yield similar success rates (“Risks of Cloning”). Opponents also note that cloned animals often have many health problems during their lives, including deformations, immune system deficiency, and various other disorders, which could also be present in human clones (“Risks of Cloning”). In addition, it is argued that if made reality, reproductive cloning will challenge the individuality of each clone and will put “undue pressure [on the clone]
Stem Cell Therapy Research Paper Stem cells are the body’s raw materials that your body produces to replace old or dying cells anywhere around the body. There are two broad types of stem cells, Embryonic and Adult stem cells. Embryonic stem cells comes from the embryos that are three to five days old. The origin of the Adult stem cells are the adult tissues. In the United States, it is not illegal to work with or create embryonic stem cell lines, but it is illegal for federal funds to be…
Cultural Biology The existence of the stem cell was proven in 1961. Since the discovery stem cell research, useful applications remain a large focus in the biomedical world. Doctors have been performing bone marrow stem cell transplants for decades. But when scientists learned how to remove stem cells from human embryos in 1998, both excitement and controversy ensued. (NIH) The excitement is due to the huge potential these cells have for curing human disease, such as diabetes, and…
Stem Cell Research By: Deuchester Mogeni print 4 copies The doctor took a cautious step into the room. This was the part of his job he hated the most. He gazed at the ailing man in the bed before him, surrounded by his love one’s. “Well?” the wife inquired. The doctor took in a breath and let it slowly out. He spoke directly to Don, the man with stage 4 mantle cell lymphoma, “You have weeks to a month to live.” He tried to avoid the looks of dismay from the other family members…
Stem Cell Research Stem cells are undifferentiated types of cells, which mean that they have the capacity to renew themselves. Their ability to differentiate into other cells is an unlimited process that can be found in all different tissues and organs. Stem cells serve as a “repairing system” for the body, meaning that they can divide without any limit to cure other dead cells. When a stem cell divides, it has the choice to either remain a stem cell or transform into another type of cell. The…
scientist working with Adult Stem Cells in the CERN Laboratory in Switzerland. I am here for you to listen to this one request. That is for you to provide funds for Adult Stem Cells ONLY. I believe that Embryonic Stem Cells are an unnecessary loss of life in the scientific research community. I am here to not only take a stand in ethical controversies, but also in what is for the good of science. Adult stem cells are a benefit to science. Stem cells are an undifferentiated cell of a multicellular organism…
Stem Cell Research A stem cell is the cell from the embryo, fetus, or adult that has, in some circumstances, the ability to reproduce itself for epic periods or, throughout the life of the organism, in the case of adult stem cells. It can also give specialized cells that make up the organs and tissues of the body. In the mid 1800s, it was discovered that stem cells are the building blocks of life. They also discovered that stem cells can create other cells. Federal Funding is limited to stem cell…
Neonatal Cord Blood Stem Cells: Haematopoietic Stem Cells Before being proven beneficial to saving lives, cord blood was discarded as waste material, now being used as a source of helpful stem cells. Since 1989, these stem cells have been used to treat children with blood diseases and is progressing to become beneficial to adults too. The, rare, stem cells found in the bone marrow can be found in the umbilical cord blood too. These stems cells can be collected without any harm or risk to the…

Mitchell Madden College Composition Section 0M Final Paper Stem Cells- The Cell That Can Save Us All Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide to produce more stem cells. Undifferentiated means it is not a specific cell, like a kidney or brain cell for example, meaning the stem cell can be stimulated to differentiate into any cell in the human body. Stem cells can be harvested in a number of different ways. In 1998, researchers…
Should stem cell research continue to be funded? Medical perspective Stem cells help in the creation of other cell types, which then can form into tissue and other body organs. Rather than surgery and medicine, these cells create a potentially new alternative method of restoring the human body to a healthy state. There are two forms of stem cells: embryonic and adult. Embryonic stem cells have no specialized functions and are pluripotent, which means they have the ability to develop into specialized…
