Cells that have the ability to become, basically, any other cell in the body are called stem cells. These cells would most likely develop in the beginning stages of life. These cells also have the potential to grow. Stem cells have the ability to divide numerous times without limit. This works as a type of repair system within the body. This way, when a stem cell does divide, the produced cells have the ability to remain a stem cell or become any type of cell in the body. When given a route, the stem cells will take on the given job as if that was their normal purpose. Stem cell cloning uses a base of two main types of stem cells. These two main types are adult stem cells and embryonic stem cells. The adult stem cell, according to the National Institutes of Health, is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ that can renew itself and can differentiate to yield some of all of the major specialized cell types of the tissue or organ. Adult stem cells usually have a specified job, and that job is to repair the tissue where they largely reside. Another type of stem cell is the embryonic stem cell. The embryonic stem cell is taken directly from an embryo, just like the name of the stem cell suggests. Usually, these embryonic stem cells are taken from fertilized embryos that have been donated with the donors consent. These donors are usually part of an in vitro fertilization experiment. In today’s society, researchers are experimenting with the possibility of producing reproductive stem cells, with the help of embryonic and adult stem cells, to completely clone another organism. The first successful clone of an adult mammal was “Dolly the sheep”. Dolly was a sheep that was born... ... middle of paper ... ...ics: In Stem Cell Information. 10 November 2013. stemcells.nih.gov/ CNN Library. 05 July 2013.

For the past few years stem cell research has been a widely debated topic; however, former President Clinton?s stance?allowing federal money to be spent on tightly controlled stem cell research?lead to intense debates over federal funding for stem cell research. There are four ways of obtaining stem cells, which are taken from embryos that are approximately one week old. They are using unwanted embryos from fertility clinics, embryos from aborted fetuses, cloned embryos, and embryos created for research purposes. Stem cells can also be taken out of adult bone marrow, but scientists do not think that adult stem cells hold as much medical potential. Conservatives are against federal funding for stem cell research because they feel that by doing such the government would be contributing to ?murder.? This idea is rooted in the religious beliefs, which include the belief that life begins at conception, held by conservatives. However, liberals support federal funding for the research of embryos because they question whether embryos are full human beings and believe the research could expedite potential medical breakthroughs.
Understanding the facts as well as procedures between the many different types of cloning is very crucial. When everything boils down there are three types of cloning known as DNA cloning, therapeutic cloning and reproductive cloning. DNA cloning is the copying of a gene in order to transfer it into another organism which is usually used by farmers in most of their crops. Therapeutic cloning is the use of stem cells used to help take the place of whatever cell is missing which is potentially used to help the ill. Stem cells contain the potential to grow and help replace the genes that are missing in order to fix whatever is genetically wrong with your body or any genes that you may be missing. Reproductive cloning actually produces a living animal from only one parent. The endless possibilities and perhaps hidden motives of using genetic engineering are what divide as well as destroy the scientific community’s hope for passing laws that are towards pro cloning. Many people within soci...
Stem cell therapy is a controversial topic that falls on the list of things not to discuss over thanksgiving dinner, very much like religion and politics. While the potential of stem cell research and therapy stand to make leaps of progression in cures for disease like Cancer and Alzheimer’s; Pros, Cons and morality still surround the issue.

One of the most heated political battles in the United States in recent years has been over the morality of embryonic stem cell research. The embryonic stem cell debate has polarized the country into those who argue that such research holds promises of ending a great deal of human suffering and others who condemn such research as involving the abortion of a potential human life. If any answer to the ethical debate surrounding this particular aspect of stem cell research exists, it is a hazy one at best. The question facing many scientists and policymakers involved in embryonic stem cell research is, which is more valuable – the life of a human suffering from a potentially fatal illness or injury, or the life of human at one week of development? While many argue that embryonic stem cell research holds the potential of developing cures for a number of illnesses that affect many individuals, such research is performed at the cost of destroying a life and should therefore not be pursued.
Stem cell research is a heavily debated topic that can stir trouble in even the tightest of Thanksgiving tables. The use cells found in the cells of embryos to replicate dead or dying cells is a truly baffling thought. To many, stem cell research has the potential to be Holy Grail of modern medicine. To many others, it is ultimately an unethical concept regardless of its capabilities. Due to how divided people are on the topic of stem cell research, its legality and acceptance are different everywhere. According to Utilitarianism, stem cell research should be permitted due to the amount of people it can save, however according to the Divine Command of Christianity, the means of collecting said stem cells are immoral and forbidden.

...oll(2010), around 33% of U.S. voters believe that taxpayers’ money should be spent on embryonic stem cell research and more than 50% of the voters disagree that taxpayers’ money should go the research(Roe, 2010). Hence, it is believed that government should not fund the stem cell research.

Could you imagine being able to create new organs, tissues, muscles, and even food? With embryonic stem cell technology, believe it or not, these things are possible. Stem cells are the body's raw materials. Specifically, they are cells from which all other cells with specialized functions are generated. Under the right conditions in the body or in a laboratory, stem cells can divide to form more cells called daughter cells. These daughter cells either become new stem cells or turn into specialized cells with a more specific function, such as blood cells, brain cells, muscle cells or bone cells. The possibilities are almost endless. The debate and main issue with this technology is that the actual stem cells come from embryos. Embryos are an unborn or unhatched offspring in the process of development. Although there is controversy surrounding these cells, embryonic stem cells should continue to be researched and used, because they have so much potential.
