Pros And Cons Of Embryonic Stem Cells

573 Words3 Pages

In this essay I plan to discuss whether embryonic stem cells should be used in the future to regenerate human organs. I will be discussing the advantages and disadvantages of using embryonic stem cells based upon my research. There are many disputes about using embryonic stem cells due to the way they are created. The ethical implications of using embryonic stem cells go against the belief of people who are “Pro-Life” (the belief that a foetus has no voice so living humans need to protect the foetus from preventable harm such as an abortion) Many people believe that culturing embryonic stem cells is basically an abortion due to the embryo dying after the stem cells have been harvested. They have proved their worth by helping people who have heart disease and can be used to regenerate badly damage human organs, some scientist are …show more content…

Embryonic stem cells are an undifferentiated cell of a multicellular organism (a foetus) which is capable of creating indefinitely more cells of the same type, and from which certain other kinds of cells arise by differentiation. They can take on any job that they need to become (based on the needs of the body) with the right conditions; they can turn into most types of cells from skin cells to root hair cells. Scientists are now trying to understand how a stem cell decides to self-renew and differentiate into a more mature cell. Another goal of the scientists research is to direct cells down certain routes,so that they become specialised cells. the reason a stem cell is harvested from a zygote, is because that is when us human are a ball of cells, waiting to be to what cell we need to become. a cell becomes the cell it needs to be when signals are sent to the cell to turn of specific

Huggies or Luv ’s I was walking through the baby section at Wal-mart and it brought back memories of the last two summers with my two year old twin niece Bailey and nephew Dakota. I keep Bailey and Dakota during the summer because they live two hours away and I don’t get to see them very often. Bailey and Dakota are hyper and very energetic.

Ian Kerridge and Ronald Fung in "Uncertain Translation, Uncertain Benefit And Uncertain Risk: Ethical Challenges Facing First-In-Human Trials Of Induced Pluripotent Stem (Ips) Cells" talk about the discovery of “induced pluripotent stem (iPS)” in 2006 and its application in cell replacement therapy, and how it changed the debate on the ethics stem cell. In the article Ian and Ronald explain how iPS is different from the regular stem cell, and how it changes the debate of ethics in this matter. The problems with the ethics and stem cells are the experiments, and use of embryos, and ova taken from women and do research with it. Although the iPS is one alternative to the stem cell research, are different from the normal human stem cells. In conclusion

The embryonic stem cells used in research come from three main sources. One source of embryonic stem cells is from leftover embryos at infertility treatment clinics (Where Do the Embryos Come From?). Once the fertilized eggs have been implanted into the mother, the rest are frozen (Where Do the Embryos Come From?). These frozen eggs are either shelved or donated to research (Where Do the Embryos Come From?). The women must give their consent for their leftover eggs to be used in research (Where Do the Embryos Come From?).

They are despecialized, so they are essentially in a sort of limbo in terms of what purpose they serve, and more importantly they can be brought out of this limbo to serve most any purpose necessary. As biologists Junying Yu and James A. Thomson state, “human embryonic stem (ES) cells capture the imagination because they are immortal and have an almost unlimited developmental potential.” Have some damaged heart, blood, or muscle cells that need replacing? Why stop there: have cells of almost any type that could be swapped for fresh spares? Through altering either the conditions of the dish in which the cells are dividing or by tinkering with the cell itself, scientists can differentiate embryonic stem cells to fulfill those

Why Embryonic Stem Cells Should be Researched Imagine, 20 or 30 years from now the medical field being radically changed. Cancer patients being cured, paralyzed victims of a car crash being able to walk and move again Even a smoker’s lungs being healed back to normal. This could all be possible with further research regarding Embryonic Stem Cells Even though one has to destroy a fertilized embryo, and some believe this is equivalent to killing a human, Embryonic Stem Cells should be used because we can make a nearly infinite supply of them and could possibly cure diseases and regrow body parts. The only real downside to ES cells are the fact that a fertilized embryo has to be destroyed to create the Stem cells.

Embryotic stem cell research is a major controversy in the United States today. This paper will provide the definition of what embryotic stem cell research is, how to get embryotic stem cells, and the process in which it undergoes, along with reasons behind the procedure. This paper will also include some positives of embryotic stem cell research such as treatment. The negatives will also be included. These will be what religions believe about embryotic stem cell research and the death of an embryo.

Editorial: embryonic stem cell research Embryonic stem cell research is a topic of that has been discussed extensively over the last two decades. Stem cells are a type of self-replicating cell that can usually differentiate to produce any specific type of cell (Liou 3). There have been many different arguments regarding these cells. Some believe that the use of stem cells will save lives in the future.

In recent years, several competing viewpoints have emerged about embryonic stem cell research. All of this debate raises an important question, Should embryonic stem cell research be conducted for treatment of present and future diseases? People who believe that an embryo should not be destroyed tend to say that embryonic stem cell research should not be conducted. On the other hand, people who believe that embryonic stem cell research creates means of curing diseases reply that the research should be conducted. Embryonic stem cell research “uses special cells found in three-to-five day old human embryos to seek cures for a host of chronic disease” (PRC).

Human embryonic stem cells are cells that are pluripotent, meaning that they are able to differentiate into any of the various cell types. Scientists are able to obtain these stem cells from eggs that have developed into embryos through the process of in vitro fertilization. In vitro fertilization is a process where the egg and sperm are combined in a lab rather than in a female. There are a few issues involving these stem cells. For these cells to have any type of use, there would need to be a sizable amount of them, which has yet to be done.

In an article written by Nancy Frazier O’Brien, she points out the fact that during a United States Conference of Bishops meeting there was a 191-1 vote in favor of a document titled “On Embryonic Stem Cell Research: A Statement of the United States Conference of Catholic Bishops”. This document basically stated that we, as a people, have crossed a certain line of morality that causes us to believe it is permissible to use a human being as a research specimen (O’Brien). This idea adds an entirely new level of difficulty when dealing with this particular conflict. If human embryos are thought of as human beings than the conflict deepens with the debate of the morality in killing one thing to save another. The conflict behind embryonic stem cell research is very difficult, and religious groups, such as the Catholic church, present a very firm stance.

Embryonic stem cell research should continue and be heavily funded due to the immense progress that it has brought towards medical innovation, the current lack of research, and the endless possibility that stem cells offer. Embryonic stem cells are cells derived from embryos that are at a stage where implantation normally occurs. Stem cells will eventually commit to a specific kind of cell, but at this point in utero, they have not which is what makes the cells so rare

A stem cell is a simple cell in the body that is able to develop into any one of various kinds of cells. There are different types of stem cells for example adult stem cells, embryonic (or pluripotent) stem cells. Adult stem cells are undifferentiated cells, found throughout the body after development. Embryonic stem cells are pluripotent, meaning they are able to grow into all derivatives of the three primary germ layers. Stem cell research is controversial because some religions believe that stem cell research is okay and others think it isn’t.

Researchers have already demonstrated that adult bone marrow cells guided to become heart-like cells can restore heart tissue in people. There is debate, however, on the ethical side of the utilization of stem cells. The controversy of the pros and cons of stem cell research clearly exhibits the problematic ethical evaluations researchers must do from time to time. All scientists must ponder whether the positive effects portrayed from their research are probable to be significantly higher than the negative effects. On the pro side, stem cell research can potentially help treat a spectrum of medical predicaments.
