Stem Cell Research
What is a Stem Cell?
Stems cells are immature cells found in embryos that can develop into any kind of specialized cells. They can form virtually any cell of the human body. These types of stem cells are known as pluripotent cells. Multipotent cells are stem cells that are more mature; they can be found in adults and children. Multipotent cells are not as flexible as pluripotent cells, as they have already developed into more specialized human cells.
Benefits of Stem Cells
Benefits of stem cell research can be overwhelming. Today, millions of people around the world suffer from incurable diseases. Stem cell research could help the scientific community find a breakthrough in developing a cure. By observing stem cells develop into mature human tissue, scientists can better understand how embryos develop. “Normal” human development can be recorded. This knowledge can be used to help prevent birth defects, for instance.
Scientists would be able to grow spinal cells from pluripotent stem cells. These cells could possibly repair spinal cord damage. Those afflicted by paralysis, such as Christopher Reeve, could possibly move again. Stem cells could also be used to grow nerve cells, possibly combating Parkinson’s disease or Alzheimer’s. While it will be many years before scientists may actually be able to find a way to combat these diseases, there is a great promise in stem cells.
Because stem cells are essentially a blank slate, scientists are theoretically capable of growing any human tissue cell. There is enormous medical potential in this. Stem cell research is the next step in advancing the medical field. It is comparable to the discovery of penicillin or the inoculation for smallpox.

...ting embryos specifically for stem cell research should not be allowed. Continued stem cell research will benefit all of mankind with its promise of medical advances. Opponents’ concerns about destroying human life will be quelled because stem cells will be taken from already doomed embryos. The federal government will be able to regulate the research and ensure that it is lawfully conducted.
Currently, the limitations on research are too restricting, as researchers are limited to resources already gathered. There are sixty existing stem cell lines today, already derived from embryos. Researchers are to only use these lines. These limitations severely hinder stem cell research. The government, especially President Bush, should re-evaluate stem cell research.

According to Silver, William Safire, columnist of The New York Times, views cloning as a way of taking someone’s identicality away. The uniqueness of the cloned person would be lacking, thus evolution would be restricted. Silver says that Safire is wrong because evolution and the progress of mankind don’t intertwine, and is unpredictable. Safire, along with almost everyone, cannot prove arguments of religion because religion is simply not provable. Silver thinks that some religious people are concerned that clonin...
Stem cells are the building blocks of the human body. Embryos consist of unspecialized stem cells that transform into the various specialized cells in the body such as cardiac, muscle or bone cells. Fetuses also have stem cells. However, the stem cells are divided into types like muscle, bone or nerves and don't perform a specialized function. Surprisingly, adult bodies also contain stem cells. In adults, stem cells are undifferentiated but limited to specific tissue type. When needed, the stem cells transform into the cells needed for repair and maintenance. The most common source of adult stem cells is bone marrow. Researchers also acquire stem cells from umbilical cords. Without stem cells, embryos could not develop into fetuses and adult
“Cloning represents a very clear, powerful, and immediate example in which we are in danger of turning procreation into manufacture.” (Kass) The concept of cloning continues to evoke debate, raising extensive ethical and moral controversy. As humans delve into the fields of science and technology, cloning, although once considered infeasible, could now become a reality. Although many see this advancement as the perfect solution to our modern dilemmas, from offering a potential cure for cancer, AIDS, and other irremediable diseases, its effects are easily forgotten. Cloning, especially when concerning humans, is not the direction we must pursue in enhancing our lives. It is impossible for us to predict its effects, it exhausts monetary funds, and it harshly abases humanity.
In conclusion, it is clear to see that cloning is not the taboo it has been made out to be. It is a new boundary that humanity has never encountered before and so it is understandable that people have qualms about ‘playing God’ by shaping a life. Although some might argue that it is immoral to clone human beings, the truth is that it is unethical not to. Given that such technology has the potential to save millions upon millions of lives, not tapping into that industry would have dire consequences on the future. In this case, the ends more certainly justify the means.
Drugs can be tested on stem cells that develop into the target tissue before using it on human test subjects, which improves safety. Finally, transplantation of organs created from stem cells could eliminate the need for human organ donors.... ... middle of paper ... ... The 'Standard' of the 'Standard'.
Imagine a world where everyone looked like you and was related to you as a sibling, cousin, or any form of relation, wouldn’t that be freaky? Although cloning is not an important issue presently, it could potentially replace sexual reproduction as our method of producing children. Cloning is a dangerous possibility because it could lead to an over-emphasis on the importance of the genotype, no guaranteed live births, and present risks to both the cloned child and surrogate mother. It also violates the biological parent-child relationship and can cause the destruction of the normal structure of a family. The cloning of the deceased is another problem with cloning because it displays the inability of the parents to accept the child’s death and does not ensure a successful procedure. Along with the risks, there are benefits to Human Reproductive Cloning. It allows couples who cannot have a baby otherwise to enjoy parenthood and have a child who is directly related to them. It also limits the risk of transmitting genetic diseases to the cloned child and the risk of genetic defects in the cloned child. Although the government has banned Human Reproductive Cloning, the issue will eventually come to the surface and force us to consider the 1st commandment of God, all men are equal in the eyes of god, but does this also include clones? That is the question that we must answer in the near future in order to resolve a controversy that has plagued us for many years.
In the essay, Cloning Reality: Brave New World by Wesley J. Smith, a skewed view of the effects of cloning is presented. Wesley feels that cloning will end the perception of human life as sacred and ruin the great diversity that exists today. He feels that cloning may in fact, end human society as we know it, and create a horrible place where humans are simply a resource. I disagree with Wesley because I think that the positive effects of controlled human cloning can greatly improve the quality of life for humans today, and that these benefits far outweigh the potential drawbacks that could occur if cloning was misused.
How should we think about cloning as philosophers and feminists? Reproduction by cloning is not, in itself, morally inferior to human sexual reproduction. Moral criticism of cloning rests on condemnation of its "unnaturalness" or "impiety," but this kind of criticism should not persuade non-believers. I evaluate cloning in two phases. First, some hypothetical situations involving private choices about cloning are examined within a liberal framework. From this individualistic perspective, cloning appears no more morally problematic than sexual reproduction. A liberal feminist may welcome the possibility of human cloning as an expansion of the range of reproductive options open to women. The second phase argues for a shift in the framework of analysis in order to get a more complete evaluation of the ethical implications of human cloning, including questions of distributive justice and the ideology of reproduction.
...ly praised, but science that interferes with the creation of human life is seen by many as entirely different. People are still unsure as to whether or not and to what extent scientists should be involved in such a realm. This is, in fact, the prevailing view. Consequently, the field of human cloning has been shaped by these attitudes. At present, human cloning both nationally and internationally is essentially an unacceptable practice. Whether scientists such as Richard Seed will be successful remains to be seen, but the consensus seems to be that the world is not yet ready for full-blown human cloning. Accordingly, efforts have been made to impede the scientific process and to push human cloning into the distant future.
Most people argue that human cloning is not morally and ethically acceptable due to both religious concerns and long-term health problems. The notion of cloning organisms has always been troublesome because of unpredictable consequences. “Cloning represents a very clear, powerful, and immediate example in which we are in danger of turning procreation into manufacture” (C...
Icarus sat behind Charon staring into the endless waters of the river Acheron; therefore his human life ended and the rest of his existence had just begun. He thought faintly about what this journey entailed, would he be consigned to the fiery pits of Tartarus or would he be treated as a hero in the islands of Elysia? He hoped he would be fortunate and possibly be given another life, maybe then he would see his father again, his thoughts were abruptly halted as the Acheron ended, “This is the end.”
Cloning, a topic that has recently caused mayhem all over the world, is possible, but will it be here to stay? The astonishing news that scientists had cloned a sheep a couple of years ago sent people into panic at the thought that humans might be next. "Cloning is a radical challenge to the most fundamental laws of biology, so it's not unreasonable to be concerned that it might threaten human society and dignity" (Macklin 64). Since most of the opposition is coming from the pure disgust of actually being able to clone species, it makes it difficult for people to get away from the emotional side of the issue and analyze the major implications cloning would have for society. To better understand this controversial issue, the pros and cons of cloning will be discussed.
"See you in two years with your cloned child," says the doctor to his patient. Such a statement sounds so bizarre and futuristic, but scientists believe cloning "is no longer the realm of science fiction" (Virginia, Sirs). Its "just a matter of time before the first cloned [humans]" (Virginia, Sirs). Although this practice does not seem dangerous, cloning should be banned because it takes away the individual importance of human beings, is too risky, and also morally wrong.
The most popular objection to human cloning is the assumption that science would be playing God if it was to create human clones. Reverend Albert Moraczewski states that cloning is intrinsically morally wrong, is an attempt to play God, and exceeds the limits of the delegated dominion given to the human race. (Madigan, 8) To say that this argument is unclear and unsupported is generous. It refuses to differentiate between cloning and the interruptions of biological processes which are viewed as commonplace in today's society. Religious objections were once raised at the prospects of autopsies , anesthesia, artificial insemination, organ transplants, and other acts which were seen to be tampering with divine will. (Madigan, 3) Yet enormous benefits have been reaped by each of these...
As an individual person and human being, we are raised with family values. We are taught about the value of marriage, parenthood and respect. Cloning will bring the demise of those values. With today's technology and cultural diversity in America these values are rapidly diminishing. "Changes in the broader culture make it now vastly more difficult to express common and respectful understanding of sexuality, procreation, nascent life, family, and the meaning of motherhood, fatherhood, and the links between the generations" (Kass and Wilson 7).
