...Stem Cell Ethics Essay In today’s society there are many things that are deemed ethical or not unethical. Underage drinking, drug use, divorce, these are just a few that might be considered unethical. Stem Cell Research can fall into either category depending on a person’s views. A stem cell is a biological cell found in every multicellular organism that can divide into different specialized cells. In a growing embryo, stem cells help maintain the regeneration parts of organs. “Cells grown in the lab provide scientists with the opportunity to "engineer" them for use in transplantation or treatment of diseases” (National Institutes of Health). There are two different types of stem cells, embryonic and adult. Embryonic cells are in the inner cell mass and adult cells are found in tissues. “Embryonic stem cells exist only at the earliest stages of embryonic development and are capable of making any cell type in the body. Under the right conditions, these cells retain the ability to divide and make copies of them indefinitely. Scientists are beginning to understand how to make these cells develop into any of the more than 200 different types of cells in the human body” (Stem Cell Research). “Adult stem cells are more limited and specialized than embryonic stem cells. They have the ability to make just one or two kinds of tissue, such as blood and immune system cells, brain or muscle cells. Adult stem cells also have a more limited capacity to replace themselves than do embryonic...

...Stem Cell Application Assignment * Stem cells are an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. Adult stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body. * Stem cells hold the promise of treatments and cures for more than 70 major diseases and conditions that affect millions of people, including diabetes, Parkinson's, Alzheimer's, cancer, multiple sclerosis, Lou Gehrig's Disease (ALS), spinal cord injuries, blindness, and HIV/AIDS. These are all degenerative diseases and stem cells help recreate whatever body material has been lost. It is prominently used in blood diseases such as leukemia. * * A stem cell transplant (also called hematopoietic progenitor cell transplantation) infuses healthy blood-forming stem cells into the body. Stem cells can be collected from the bone marrow, circulating (peripheral) blood, and umbilical cord blood. * Yes, stem cells are being used to treat leukemia. It prolonged the life of my grandpa who suffered from leukemia by six years. * The controversy surrounding stem cell research led to an intense debate about ethics. Up until the recent years, the research method mainly focused on embryonic stem cells, which involves...

...research on how stem cells make new kidney tissue, and he did this using zebra fish. A stem cell is a unique in two ways: it is an immature cell that can turn into different cell types and it can self-replicate. Zygotes are the ultimate stem cells. To get a stem cell you can take a skin cell and force it to express 4 proteins or genes. Getting a stem cell from a zygote is controversial because some people ask if destroying an embryo is ethical. You can use stem cells for therapy. You take stem cells and turn them into the target cell and then transplant it into the person. Stem cell therapy does not have any FDA approval. There is no...

...Is Embryonic Stem Cell Research Humane? Melvin Hart EN1420 12/1/14 ITT Technical Institute Is Embryonic Stem Cell Research Humane? Stem cells are primitive cells with the capacity to divide and create more identical stem cells, or to specialize and form specific cells. “Embryonic stem cells” which can only be derived from embryos that is still in the womb. They also have the ability to form cells of all tissues of an adult. So they can be manipulated to create new body parts for any human. This research can help with many new and exciting fields in medicine. HES cells are derived from the ‘inner cell mass’ of human embryos that develop in culture in 5 days of fertilization. It does not contain Extra embryonic tissue, which is needed for complete human development, which develop things such as the placenta and membranes of the fetus. So they cannot create a complete new individual in any way shape or form. Just spare parts for a lack of better words. This is why this research is so controversial to almost everyone who knows anything about it. Even the scientist who first discovered this technic have argued about it being just as controversial as abortion because you have to have a fertilized fetus to obtain the cells needed to do this process. So it touches an issue that has been around for years. When does life really start? When an egg is fertilized or when the mother has given birth? Or once the fetus has developed a brain? Really tough question, however I don’t...

...Cells are defined as “a type of cell that can produce other cells which are able to develop into any kind of cell in the body.” There are two main types of stem cells. The first are called Embryonic Stem Cells. They come from 4 to 5 day old embryos that have been fertilized by in vitro fertilization. They are then donated by the donors for research. canThe second are called Adult Stem Cells. They can be found in human tissues such as the blood, bone marrow, liver, brain and some muscles. People have been studying stem cells since the nineteenth century. On February 2, 1963 two Canadian scientists experimented on mice and found evidence that there are stem cells in blood. Their names are Ernest McCulloch and James Till. In 1968 Robert A. Good performed the first successful bone marrow transplant on a child. This child suffered from an immune deficiency that had killed other people in his family. He grew to be a healthy adult....

...During this day and age lots of people still think to themselves ¨what are stem cells, ¨ I Have heard that a lot I´ve had to look back as well to find the exact meaning of what a stem Cell does what people in this day in age use them for. Stem cells are undifferentiated cell of A multicellular organism that is capable of giving rise to infinitely more cells of the same Type, from which certain other kinds of cells arise from differentiation. The main study on this is they are taking human body and using it to, test, and grow stem cells or even master cells and they form immediately after the human egg is fertilized. Which the cells are called master or stem, because they can develop into all parts of the body including muscles, brain, blood, and skin. The way I feel about them...

...Stem cells are an undifferentiated cell of a multicellular organism that can give rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. Over the years, scientists have learned much more information on stem cells. The information on stem cells has only improved which led to new technologies, cures, and of course controversies. Stem cells are incredible, they are unlike any other cell in the body. They have three unique properties: they are unspecialized; they are capable of dividing and renewing themselves for long periods; and they can give rise to specialized cell types. A stem cell is unspecialized meaning that they are basically blank body cells. They have the potential...

...Stem cells are unspecialized cell, they are cells that have the potential to develop into any type of cells in the body. Stem cells are served as sort of a repair and replace system. Our bodies create stem cells to repair or replace damaged or worn out tissues in the bodies, this is why stem cells are very important to all living organisms as they are the cure for our bodies. Stem cells have a potential to renew themselves through division systems. It can be divided with no limits to create new cells for the body to use. When a stem cell divides, each stem cell can either remain as a stem cell or becomes specialized function cells such as a red blood cell, a brain cell or a muscle cells. Because stem cells have unique ability scientists are very interested in doing the research and hopefully will develop the research into medical treatments. My question to this issue is should stem cell research be carried out in New Zealand for medical treatments. Scientists are now working on two kinds of stem cells from human and animals which are embryonic and adult stem cells. A major difference between embryonic stem cell and adult stem cell is their abilities in the numbers of different types of cells they can become. Embryonic stem cells have the ability to...

...At first glance, teenagers may view stem cells as a boring topic that only adults debate about. But what if these stem cells could cure their diseases or injuries one day? Stem cells, specialized cells that can develop into almost any type of cell, typically do not come up in an everyday conversation. However, due to recent breakthroughs in science, doctors have researched and tested stem cells and their effect on the human body. Although the controversy of using stem cells may not be a teenager's primary concern, they need to keep it in mind as scientists discover more information about stem cells, which doctors could use to treat injuries and heal diseases. Ever since the mid 1800's, scientists have explored stem cells characteristics...

...Stem Cell research is very controversial topic, but to understand what is stem cell we must first understand what exactly is it. According to Matthew C. Nisbet “When it comes to public opinion about controversial issues related to science and technology, many policy makers and scientists assume that increased public understanding of science will lead to increased public support. So as people understand science, and the research behind stem cell, than we can get support for it, but will it work”. Stem cells are unspecialized cells capable of forming into any different type of cells through cell division. They are very important, because they can form any type of human organ, and bones. Scientist have found some major research to turn stem cells,...

...Stem cells are cells that are not yet specialized but are able to be specialized to do a specific job or create a certain object within the body, for example, skin, muscle, or bone. There are many positives when working with stem cells, like curing diseases and fixing bones by regrowing new ones. On the other hand, stem cells are mostly taken from an embryo which creates a lot of ethical and controversial issues. Disassembling embryos, human cloning, and the fact that the treatments may not work are all negative effects of stem cell research. Many believe that at the moment of conception there is another life growing inside of you. To take that life and disassemble it to save another human life is perceived as unethical because the embryo does not get a say in the matter for what the human race is paying to have done to it. Thankfully, in 1996, there was a legislation created prohibiting the use of taxpayers’ money toward stem cell research, but still many private groups continue to fund for the researchers which cause many people to fight...

...ways to derive embryonic stem cells from mice, eventually gaining the knowledge to extract them from humans, in 1998. Embryonic stem cell research is when an egg and sperm cell is obtained from a donor, mixed in a Petri dish, and the egg is fertilized to produce a stem cell line for research.The scientists begin this process by conducting in vitro fertilization, or an egg being fertilized out of the womb, and into a lab setting. A stem cell is essentially a “blank” cell, that’s capable of becoming another more differentiated cell type in the body, such as a skin cell, a muscle cell, or a nerve cell. In this case, a host cell where the embryo can prosper and grow to be used later on for research. In humans, mice, and other mammals, the embryo is a ball of approximately one hundred cells at this stage. Although embryonic stem cell research has great potential in deciphering the cause behind puzzling disorders such as Type 1 diabetes, Parkinson's, and heart infractions,...

...Ron Kind said, “More important is the fact that embryonic stem cell research could lead to new treatments and cures for the many Americans afflicted with life-threatening and debilitating diseases." Human Embryonic Stem Cell Research is greatly debated between religious and scientific groups. “Killing the embryo” or scientific research to figure out how to save others, regrow bad organs, and solve the mysteries of many diseases. Embryonic cell research may sound like a horrible ordeal but could help us solve many issues that are dealt with today. First off there is the fact that we should probably understand what it is. Embryonic stem cells are the cells of the inner cell mass of a blastocyst, which is an early-stage embryo. Human embryos reach the blastocyst stage 4-5 days post...

...The 21st century is characterized for its technological advancements. Rapid renovation in medical research, disease treatment, and advanced quality of life has marked the turn of the century. Recent development in stem cell research has brought forth an ethical debate; whether research to achieve new medical remedies is permissible at the stake of, arguably, the unborn life of frozen embryos or if stem cell research should cease at the cost of disease stricken people worldwide to preserve an embryo that may never be born. 1. Massage (Articulate) the Problem: a) What is the current undesirable situation? Identify and define issues in the dilemma. The current undesirable situation pertaining to frozen embryo donation is the donor being forced to keep frozen embryos against their own discretion. It may be unfavorable to keep embryos frozen for an extended period of time because of the financial burden. To extract, freeze, and preserve embryos, clients can expect to pay an initial fee of approximately $10,000. According to USCFertility, client can also expect a storage fee of $500 per year and to thaw frozen embryos an additional payment of $5,000 is required (uscfertility.org). Another issue apart of this ethical dilemma is whether embryos are classified as a person or property. If assumed to be property, it is debatable whether preservation of embryos can be mandated. Lastly, and perhaps the most controversial component of this dilemma is defining “conception” to establish when...

...degenerative diseases, thereby defective genes could be replaced and help improve the lives of millions. However, cloning in the human sense has had a difficult start. DNA cloning has permitted the development of modern biology, in particular within the last forty years. In this time frame the world has passed from theories to actually cloning genes. Subsequently, The University of Utah Health Sciences did a study on the history of cloning: Mitalipov and colleagues were the first to use somatic cell nuclear transfer to create a human embryo. …In this experiment, researchers took a skin cell from a patient and fused it with a donated egg cell. Key to the success of the experiment was the modification to the culture liquid in which the procedure was done and to the series of electrical pulses used to stimulate the egg to begin its division. Following the cloning controversy of 2004–2005, in which South Korean scientists falsely claimed to have used somatic cell nuclear transfer to create embryonic stem cell lines, the scientific community demanded much stronger evidence that the procedure had actually been successful. (Learn. Genetics) Subsequently, many states in the US began to prohibit the use of therapeutic and reproductive cloning. Regardless, cloning should be decriminalized, with the stipulation that serious regulations be put into place. People, often too caught in the moral implications of cloning never take the time to learn the scientific process. Moral implications are thoughts...
