Stem cells have the ability to develop into many different cell types in the body throughout life and growth. Examples include bone marrow, the heart, and the pancreas. Stem cells have two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division. Unspecialized stem cells are cells that have no special function Second, they can be generated to become tissue- or organ-specific cells with special functions. Stem cells divide to repair and replace worn out or damaged tissues sometimes regularly or under special conditions depending on the type of tissue (Stem Cell Basics, 2009).
Stem cells are very important for living organisms to stay healthy and survive, and for many other reasons. In a blastocyst, which is a three to five day old embryo, the inner cells give rise to the entire body of the organism. All stem cells have three unique, general properties: they are capable of diving and renewing themselves for long periods, they are unspecialized, and they can give rise to spec...

- In present days of life in The United States, research has become a viable tool for sustaining and prolonging human life. As research evolves, it brings along with it much controversy, especially where stem cell research is involved. Stem cell research can bring new insight to today’s medical field. This may be the way of finding solutions concerning many health injuries and diseases which would diversely be thought of as implausible. Thoughts can be influenced by Deborah White, in Pros & Cons of Embryonic Stem Cell Research, “Embryonic stem cells are thought by most scientists and researchers to hold potential cures for spinal cord injuries, multiple sclerosis, diabetes, Parkinson's disea...

- Stem Cell Research This research paper will focus on stem cell research and the ethical issues that are attributed to this subject. This topic will be narrowed down to Embryonic Stem Cell research in that there is a great debate going on how to conduct this research ethically. The importance of embryo stem cell research is that the research could help save lives and also the debate is that it is morally wrong to kill an embryo due to the fact it still a living organism. The issue with embryo stem cell research is that an embryo is a living being and should not be used for research, because then the embryo would not be allowed to develop into the living form it is meant to be....

- INTRODUCTION Ethical issues are those issues which at a personal, community or global level challenge the reader to make decisions of what is right or good behavior. Morality however refers to codes that are held about what is right and good behavior (Engebreston, 2006). In today’s world medical research and technology is rapidly changing and there are increasing ethical conflicts between science and religion particularly with the recent harvest and research of embryonic stem cells. The use of embryonic stem cells has been described by “Chris McDonald, stem cell research centre, 2008” as one of the most significant breakthroughs of this century in biomedicine....

- The Controversy Over Stem Cell Research In a lab at the University of California, a scientist carefully isolates several cells and locates them to a petry dish. A few days later, he returns to find the cells pulsating like a human heart (Gorman 58). This account has actually been occurring at several scientific labs across the nation. These cells, known as stem cells, produce nearly all the other cells and tissues found in the human body (Sobel Sep 4, 22). Intensive research has found that when these stem cells are grafted with human tissue, new tissue is formed and the diseases found in that tissue are cured....

- The Moral Debate over Stem Cell Research President George W. Bush looked stern and confident as he addressed the American people on August 9th, 2001. It was an historic day for the 43rd president, as he explained the debate surrounding embryonic stem cell research, including its possible benefits for science but also its problems surrounding morals and ethics. “The issue is debated within the church, with people of different faiths, even many of the same faith coming to different conclusions,” Bush said....

- Stem Cell Research The topic of stem cell research does not affect me so much at the moment. It might in the future, but for now it does not. I do believe that stem cell research should be used for cloning organs that will be used for organ transplants. I do not however think that parents should place the doctors on pedestals just because these “mad scientists” supposedly have the power of God. The topic of heated debate does intrigue me, but not to the point as to where I would make a career of it.... [tags: essays research papers]

- Embryonic Stem Cell Research Stem cells are the newest "hot" topic in biological research. Very few other ongoing areas of research have been the focus of numerous articles, Presidential and Congressional scrutiny, and numerous ethical debates played out in the national media. This ongoing focus on stem cells is due in part to their amazing potential and in part to the controversial nature of one type of stem cell—the embryonic stem cell. The key question that is being dealt with is the issue of Federal funding for research with embryonic stem cells; the underlying issues of this simple question cause strong opinions and necessitate serious ethical considerations....

- Stem Cell Research Should stem cell research be allowed. Stem cell research has been a major biological breakthrough in recent years. It has great potential to help people and ease suffering. But there is also a moral question raised about stem cell research, and that comes from the source of stem cells. Ever since Stem Cell research started, there has been much debate over whether or not it should be allowed. Some people are completely against stem cell research because the stem cells are often taken from aborted pregnancies, they consider it murder.... [tags: Papers Essays Science]

- Stem Cell Research Few recent scientific issues have stimulated so much media attention, public debate and government involvement as that of stem cell research. Stem cells offer people hope by promising to greatly extend the number and range of patients who could benefit from transplants, and to provide novel therapies to treat debilitating diseases such as diabetes, Parkinson?s, Huntington?s, heart disease and stroke, as well as accidental damage such as spinal cord injury. So why would anyone object to research in this area.... [tags: Stem Cells Science Biology Essays Argumentative]

- Stem Cell Research Using stem cells in their research, scientists are able to discover new information that leads to advancements in the scientific society. However, what many people do not understand is that stem cells are unlike other types of cells, and this is because of two significant characteristics. These differences lead to a lot of controversy, as you'll soon see. First, stem cells are able to renew themselves for long periods of time through the process of cell division, thus making them specialized cells....
