State laws may restrict some or all sources for embryonic stem cells or specifically permit certain activities. State laws on the issue vary widely. Approaches to stem cell research policy range from laws in California and New Jersey, which encourage embryonic stem cell research, including on cloned embryos, to South Dakota's law, which strictly forbids research on embryos regardless of the source. If, however, a fetus is aborted for the health of the mother in South Dakota, the fetus may be used for research purposes with maternal consent. Many states restrict research on aborted fetuses or embryos, but research is often permitted with consent of the patient. Almost half of the states also restrict the sale of fetuses or embryos. Louisiana is the only state that specifically prohibits research on IVF embryos. Illinois and Michigan also prohibit research on live embryos. Finally, Arkansas, Iowa, Michigan and North Dakota prohibit research on cloned embryos. Virginia's law also may ban research on cloned embryos, but the statute may leave room for interpretation because human being is not defined. Therefore, there may be disagreement about whether human being includes blastocysts, embryos or fetuses. California, New Jersey and Rhode Island also have human cloning laws, but these laws prohibit cloning only for the purpose of initiating a pregnancy, or reproductive cloning, but allow cloning for research. Missouri also forbids the use of state funds for reproductive cloning but not for cloning for the purpose of stem cell research, and Nebraska prohibits the use of state funds for embryonic stem cell…...

...-Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. I think by using Stem Cells to cure a disease is a good thing and that the research should continue. -Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions. Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. "This is not about red states and blue states. This is not......

...Recent advances in human stem cell research have not only generated enormous enthusiasm on the part of researchers and optimistic predictions of revolutionary advances in biomedicine, but have also sparked considerable ethical and emotional public debate. There has been much controversy in the press about pros and cons of stem cell research . The important question to think about is Why the prospect of stem cell therapy has been greeted not as an innovation to be welcomed but as a threat to be resisted? The enormous capabilities of stem cells announce the beginning of an extraordinary advanced field of medicine that can help to cure deadly diseases . The present method , however, destroys human blastocyst that gives rise to intense controversy. (Monroe, Miller, & Tobis , 2008, p. 1) Stem cell controversy is the ethical debate centered on research involving the creation, usage and destruction of human embryonic stem cells. Around the world, many people believe that human embryo research , including the deliberate creation of embryos for valid research or clinical purposes , is wrong . Due to the controversy , some people argues that we should allow stem cell research but some of them are not in favour of stem cell research . According to S Holm , the author of Going to the Roots of Stem Cell Controversy, “A stem cell is a non – differentiated cell that can divide and multiply in its undifferentiated state, but which can also give rise to more......

Obama said his decision was a “difficult and delicate balance”. He said he wanted to side with the majority of Americans, who did support federal funding for this research. (“Obama reverses Bush-era stem cell policy.” 1) The benefits of this research can lead to new, more effective treatments for human ailments. Stem cell therapy has alleviated the suffering of thousands of people. Unused stem cells are being discarded instead of being used for research.

...The Ethical Issue of Stem Cell Research Shawn Black PHI 107 Professor Joseph Scahill November 14, 2008 Stem cell the new frontier of medical break through poses an important ethical dilemma for humanity do we support the destruction of embryos to further science or do we support the protection of embryos. We are faced with a critical decision to protect embryos from being a part of a science experiment or do we think that it is ethical to kill a few embryos in the name of science. I will discuss the pros and cons of stem cell research. I will discuss the positive outcomes associated with stem cell research from a medical aspect and the negative outcomes from a biological aspect. I will also argue for stem cell research and against stem cell research. What is Stem Cell Research? Stem cell research is the use of cells retrieved from embryos which are capable of becoming all or many of the 210 different types of tissues in the human body. Stem cells have traditionally been defined as not fully differentiated cells or tissue types. The use of these undifferentiated cells or tissues is used to replicate cells in the human body. These cells are from embryos fertilized between days 5-7 of human development. The cells are then retrieved from the embryo and used by researchers to replenish dying or damaged cells in the body. These cells show great promise to help solve medical illnesses and diseases. The argument we face with this type of research......

...Stem cell A stem cell is essentially a “blank” cell, capable of becoming another more differentiated cell type in the body, such as a skin cell, a muscle cell, or a nerve cell. Microscopic in size, stem cells are big news in medical and science circles because they can be used to replace or even heal damaged tissues and cells in the body. They can serve as a built-in repair system for the human body, replenishing other cells as long as a person is still alive. Adult stem cells are a “natural” solution. They naturally exist in our bodies, and they provide a natural repair mechanism for many tissues of our bodies. They belong in the microenvironment of an adult body, while embryonic stem cells belong in the microenvironment of the early embryo, not in an adult body, where they tend to cause tumors and immune system reactions. Most importantly, adult stem cells have already been successfully used in human therapies for many years. As of this moment, no therapies in humans have ever been successfully carried out using embryonic stem cells. New therapies using adult type stem cells, on the other hand, are being developed all the time.  Significance of the Study Stem cell therapy is a potential treatment for spinal cord injury and different stem cell types has been grafted into animal models and humans suffering from spinal trauma. Due to inconsistent results, it is still an important and clinically relevant question which stem cell type will prove to be therapeutically......

...ENGL 1010 Argumentative Paper: The use of embryonic stem cells for research. Stem cells are the center of large debates in today’s medical world. Stem cells are cells that are in an undifferentiated state and have the ability to transform into any kind of tissue depending on what the cells around them are. This ability to transform into any cell of the body makes them very interesting in medical research because they may have the ability to regenerate damaged human tissue. If adult stem cell research seems promising to cure some diseases, the research on embryonic stem cells seems unavoidable. That research is very controversial because those cells need to be taken from a live embryo; taking those cells will ultimately kill it. The embryonic stem cell research could lead the medical profession to find cures for diseases, giving hope to thousands of people, but is it worth killing a potential life for saving an existing one? Stem cells have a very high price (the lives of those embryos), but so many of those embryos may be destroyed anyway. Now, because the government does not want to take a real position on the problem, stem cell research is authorized as long as it does not use federal funds. Strict rules should be written encouraging research on stem cells but restricting the ways those embryos are collected, thereby allowing the United States to advance in modern medicine. Stem cells are cells that are undifferentiated. This means that they have no function yet;......

...Experimentation Critique Stem Cells Abstract According to human guidelines, human stem cell research is questionable. The main ethical dilemma revolves around whether or not an embryo is a human being of a cluster of cells. Stem cell research has the ability to provide treatment for many of today’s incurable diseases and disorders, and it is apparent this type of research produces many ethical issues in which one can consider both positive and negative for such research. Experimentation Critique Introduction Stem cell research is a modern method of discovering new medical break throughs. Research is involoved, using human embryos, causing heated moral debates. Human –nature and goal-based ethics theories apply to this controversial debate. The debate lies in the determionation of the embryos with moral status is owed. There has been extensive research in the underlying law and religious ethics surrounding the use of embryos for medical reasons. Discussed, is the debate, controversy, and opinion of government officials, in relation to the ethics involving stem cell research. Issues/Conflict Stem cell research proposes many ethical issues. The basis of this issue is that embryonic stem cells research holds such vast promise for so many people but obtaining the cell means destroying embryos. The ethical conflict brought on by stem cells means destroying embryos. The ethical conflict brought on by stem cell research is whether or not it is acceptable by social......

Stem Cells

...A Pluripotent Challenge Recent advances in human stem cell research have generated enormous enthusiasm on the part of researchers and optimistic predictions of revolutionary advances in biomedicine. These same advances have also sparked considerable ethical debate. The main ethical challenges associated with stem cell research have to do with the source of those cells. Although some advances have been made in the use of adult stem cells, the consensus seems to be that the most promising categories of stem cells are embryonic stem (ES) cells (derived from the five- to seven-day-old embryos known as blastocysts) and embryonic germ (EG) cells, derived from immature aborted fetuses. In fact, there are four main sources of (non-adult) stem cells, and each presents its own challenging ethical issues. The first such source (of ES cells) is the surplus embryos that are a by-product of the activities of in vitro fertilisation (IVF) labs. One ethical concern here has to do with the status of the embryo itself. The degree of respect that ought to be granted to a human embryo is highly controversial. Some hold that the embryo - genetically human and a potential person - deserves our full respect and protection. Others hold that while the embryo may be genetically human, it has (particularly at early stages) none of the characteristics of persons. It is not conscious; it is not self-aware. It is a cluster of cells with no independent ethical status. Still others hold an in-between view,......

..."Embryonic stem cells...are in effect, a human self-repair kit," (Christopher Reeve, activist – Larry King show). For the advancement of science, stem cells are infinitely valuable, especially when considering all the potential applications in the field of medicine. Stem cells usage is a very controversial topic, because most people think of abortions, cloning, and other negative topics when they here the term stem cells. However I think those thoughts are because they don't understand what a stem cell is, where it comes from, or its monumental possibilities that could greatly benefit the medical field. In today’s medical world there is so much that can be done with stem cells whether it is generating new organs or saving an individual with terminal disease? There are already demonstrations of Stem cells possibilities, because treatment with stem cells has already begun. They have been taken from umbilical cords and become healthy red cells used to cure sickle-cell anemia. Stem cell therapy is also being used against certain types of cancer. Stem Cells are valuable due to the fact that they are non-designated and they have the ability to divide and multiply indefinitely. Thus, theoretically stem cells could fix and even replace any damaged or lost specific cells within a body. They are easily found in early embryos, but their numbers variety for development seems to become less in the adult stem cells. The information above is only what we know right now, but that's just......

...Stem cell research is a highly controversial topic that may possibly hold the cure for cancer and other diseases. A group of scientists in the late 90’s created several techniques to isolate and grow stem cells. We to need to discuss several topics before an argument can be made to support or not support stem cell research, the types of stem cells, the uses, and who should fund stem cell research. There are many different types of stem cells and each one has a different role in promoting breakthroughs in the many diseases that can possibly be cured. There has been fierce debate in the world about research using embryonic stem cells compared to using adult stem cells. The main criticism against embryonic stem cell research is that the embryo is destroyed in the process of accessing the stem cells during the research period. It is an intriguing how the human body repairs and replaces the cells and tissues of certain organs, but not others. A great example is a burn victims cannot regenerate their own damaged tissues. Trying to figure out why scientists are now focusing their attention on adult stem cells is still a mystery. Evidence shows us that stem cells are present in far more tissues and organs than once known, and that they are capable of developing into more cells than previously thought. Adult stem cells posses the great advantage that an embryo does not. The development of cell therapies can be generated from adult stem cells. For instance, there......

...2013 Formal Essay I Stem Cell Controversy Religion and science, two forces that mix as well as oil and water. For thousands of years people have argued which side is correct: one extreme will tell you that a strong faith in God will lead to a better life, the latter extreme will tell you that life has many more complexities than just a faith a deity. These two both see life differently, the Christians think life should be cherished no matter how small or suffering. While science believes there can be something extracted from one’s small life, scientists have found, that the earliest cells of an embryo can be developed into any sort of cell. The study of this is known as stem cell research. The inner cell mass of blastocyst is extracted from the woman’s ovaries and differentiated into embryo bodies and from there they differentiate into either neuronal or pancreatic cells (bethesda). From here, it is difficult to produce enough stem cell lines or to produce the correct cell type (National Cancer Institute). This finding can save or increase many humans quality of life. But is it ethically correct? Is it morally correct? Could these findings interfere with the “circle of life”? Could this interfere with the genetic code of humans and astronomically change the world forever? Are we interfering with God’s will or the circle of life? The history of stem cell research is brief. In 1962, a new frog was produced by taking an adults frog’s intestinal cell and transporting......

...One of the most popular clinical studies being researched these days is stem cell transplantation. Until recently, moral issues of states and countries haven't allowed research to expound deeply into the unknowns. Within the last ten years though, scientists have made leaps and bounds in finding out concrete facts that this stem cell research has supplied. New ways of conducting stem cell research have made the healing and repairing treatment for many diverse applications. To prove their point, scientists have broken down the basic facts of their studies throughout the last ten years. Embryonic stem cell transplantation is a related course of cells that are in charge of certain functions and systems of the body. The cells used in the transplantation process are contrived from "cryopreserved suspensions" from the fetal liver, thymus, bone marrow, spleen, brain, and the pancreas. Introducing these cells to the body can be approached in different ways. The first step taken is engrafting or multiplying cells in the affected area. These cells will then supplement missing or declining cells and replace/repair missing functions of the body. Production then commences with considerable amounts of biologically active substances such as nerve growth factor, tumor necrosis factor and interleukins etc. When these cells have been transplanted, they are capable of migrating, establishing intercellular links and responding to various effects. However...

When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. Different types of stem cells Embryonic stem cells - These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs, although their use in people has been to date limited to eye-related disorders such as macular degeneration. Adult stem cells - These 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. Until recently, researchers thought adult stem cells could create only similar types of cells. For instance, researchers thought that stem cells residing in the bone marrow could give......

...English 102 Stem Cells: There are 3 main types of stem cells- embryonic, adult, and induced pluripotent, that provide great advances to modern medicine (Power). In recent years, the discussion of stem cells has become that of a political and moral debate. There are many misconceptions about stem cell research. The advantages far outweigh the disadvantages. “Stem cells promise great advances in the treatment of injury and disease, but many problems must be overcome before their potential can be realized.”(qtd. in Power) Before an opinion can be developed on if stem cells should be used, one must know what and how they are used. Stem cells have caught the eye of scientists since the early 1800‘s where cell propagation and differentiation were witnessed for the first time. It was a Russian histologist named Alexander Maksimov who, in 1908, first put forward the existence of the stem cell (and coming up with the term himself) as part of his theory of hematopoiesis (What). According to Maksimov’s hypothesis, all cellular blood components were derived from hematopoietic stem cells(What.). However, there had been no major developments in the field of stem cell research for some 60 years after Maksimov’s theory was proposed In the early 1900‘s European researchers made the discovery that all blood cells and platelets came from a specific ‘stem cell’(What.). However it was not until later in 1963 that the first quantitative......

...Pierron March 28,2016 Stem Cell Research Stem cells are a different from other cells in the body. Three general properties are common to all stem cells: (1) they are unspecialized (2) they give rise to specialized cell types and (3) they can divide and renew themselves for a long time. Unlike nerve cells, muscle cells and blood cells, stem cells rapidly reproduce. Millions of cells can be grown in the laboratory from a beginning group of stem cells. The unspecialized stem cells are capable of long term self-renewal like parent stem cells. There are two types of stem cells: embryonic and adult stem cells. Also there are some advantages and negative things about stem cells. Stem cells are an important part for living organisms for serval reasons. Blastocysts are 3 to 5 day old embryo. They encompass the whole body including specialized cells and organs. Adult stem cells focus more on the cells that need to be replaced that were injured, diseased or worn out. Adult stem cells are rare and hard to isolate and grow. Embryonic stem cells are fairly easy to grow in a lab. The unique abilities stem cells offer is potentially treating diabetes and heart disease. There is still a lot of work that has to be done by the clinic and laboratory to understand how these cells can be used for cell based therapies to help treat disease. Since stem cells are unspecialized, they can give rise to specialized cells including nerve cells, blood cells and heart cells. This process is......
