Embryonic Stem Cell Research Embryonic stem cells offer hope for new therapy. They are the cells from which more than 200 different kinds of tissues in the human body originate. Stem cells are the building blocks of all specialized cells; they are the raw material. Under the right conditions, they divide to form daughter cells. From there they become new stem cells or differentiate into specialized cells with a specific function, such as blood cells, brain cells, or bone. Stem cells could also differentiate into specific targeted cells to replace diseased cells with new, healthy ones. In the process of the development of humans, a zygote is a stem cell. A zygote is called a totipotent stem cell because it has the potential to form an entire …show more content…
They are isolated by breaking open an embryo and removing the inner cells. This process necessarily destroys the embryo. This procedure is usually performed on a two-year-old embryo following the division of the fertilized cell into eight different blastomeres. Embryonic stem cells could be extracted from blastomeres, but usually harvesting such stem cells necessitates the destruction of the embryo. Embryonic stem cells can, however, perform all the wonders claimed for them in tissue regeneration and differentiation. One author describes the wonders of embryonic stem cells as “apparently limitless growth in the lab dish.” Many tests have been proven to demonstrate that embryonic stem cells can form many different tissues that are functional. In a peer reviewed article written by Ole Johan Borge, the use of embryonic stem cells in the clinic is described. He says, “Stem cells are currently only being used to a limited extent in routine clinical practice. However, there is considerable hope that stem cells can be utilized in the treatment of a wide array of human disorders by replenishing lost or unfunctional cells. Diseases like Alzheimers, Parkinson, immune deficiencies, anemia and type I diabetes are all candidate diseases potentially suitable for stem cell-aided therapy.” So far there is evidence that embryonic stem cells cultured in the lab is extremely beneficial. There have been studies performed on animals that …show more content…
Embryonic stem cell research is unethical and should be discontinued. Mark S. Moller opens his article by saying, “The first one concerns the debate over the Stem Cell Research Enhancement Act (H.R. 810), passed by the United States Congress in 2005 and 2007, and vetoed by President Bush both times.” Embryonic stem cells is not the only means to obtain stem cells. There are alternate methods for obtaining stem cells. Other methods include: adult stem cell from bone marrow and cord blood stem cells. An article written by Bernard Lo and Lindsey Parham addresses two alternate methods for obtaining stem cells. It says, “Adult stem cells and cord blood stem cells do not raise special ethical concerns and are widely used in research and clinical care.” To avoid the ethical dilemma of destroying a fetal life for the lives of other people, adult stem cells and cord blood stem cells could be implemented instead. If other methods could be used, then there should be no reason to continue destroying lives for stem cell research. Embryonic stem cell research is unethical and should, therefore, be
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
Unquestionably, stem cell research is unethical on multiple accounts. Firstly, embryos are human beings and even though they’re a few days old they are not a “pre-embryo,” a term stating that after conception, the embryo was actually not an embryo. Thankfully, that term is now known as scientifically invalid. As soon as the
Stem cells are pluripotent cells of the body which are “undifferentiated.” This means that stem cells can ultimately give rise to any type of body tissue. Thus stem cells have the potential to cure a vast number of diseases and physical ailments including Parkinson’s, diabetes, spinal cord injury, and heart disease. Consequently, stem cell research and the development of associated medical applications are of great interest to the scientific and medical community. The area of stem cell research involving human embryonic stem cells is of particular interest in that embryonic stem cells are derived from week-old blastocysts developed from in vitro fertilized eggs. As opposed to adult stem cells, which must undergo a complicated process of de-differen...
This report does a fairly comprehensive job on educating the public to the definition of stem cells, describing them as “a diverse group of remarkable multipotent cells that are relatively undifferentiated and unspecialized cells of the body.” Stem cells have the capacity for unlimited self-renewal and the possibility to produce differentiated descendant cell types. The main in...
As technology stem cell research intensifies, so does the controversy about whether such scientific progress is moral. In the past millennium to today the present stem cell research has become a controversial topic across the world. Stem cells are unspecialized cells that have unique regenerative abilities, allowing them to divide into specialized cell types. Understanding why these processes occur is essential to curing disease. Critics of stem cell research argue that the extraction of embryonic stem cells involves destroying an early embryo, equating the act of killing a human. Although stem cell research is a highly controversial topic, it is compulsory to continue stem cell research within ethical boundaries for the benefit of mankind.
I think that stem cell research has advanced in so many ways, with all the discoveries being made, and the new possibilities being explored. Although it still remains unethical because embryonic cells are one of the sources of stem cells. Why is somebody else’s life more valuable than someone else? Just because an embryo cannot talk, doesn’t mean, its life has any less value than a normal human being.
Stem cells are mother cells that have potential to develop into a new different cell in the body. It can self-renew or multiply while developing into other types of cells, for example they can become cells of the blood, heart, bones, skin, muscles and brain. Stem cells were discovered in human cord blood in 1978, and in 1998, Thompson, from the University of Wisconsin, isolated cells from the inner cell mass of early embryos (early stage of an animal or person before it is born) and developed t...
The importance of embryonic stem cells rests in their lack of specialization. These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body. Being self-renewing, they offer a potentially limitless source of cells and tissue. (Tucker)

Embryonic cells should be allowed to be used because of the medical benefits they provide. They can be used to cure diseases such as Parkinson’s disease, diabetes, traumatic spinal cord injury, Duchenne’s muscular dystrophy, heart disease, and even vision and hearing loss (nih.gov 2009). There is no problem using them for medical purposes and it is not immoral to use them for this reason. Embryonic cells have the potential to save lives. Therefore, the usage of embryonic cells outweighs the ethical issues.
Those who favour stem cell research are optimistic about the continued developments in stem cell research will open doors to many breakthrough discoveries in biomedical science. The scientific and ethical questions arise as rapidly as the reaching of milestones in stem cell research. There are two main types of stem cells, namely embryonic stem cells and adult stem cells. Adult stem cells are undifferentiated cells in our body. But they have restricted-range of cells that they can further differentiate. On the contrary, embryonic stem cells have the ability to differentiate into nearly two hundred cell types in the human body, called pluripotency. The process of harvesting embryonic stem cells involves destruction of embryos (Mooney, 2009).
Within the past few years, scientist have made several breakthroughs with human stem cells. These breakthroughs have catapulted the issue of stem cell research into the middle of a national debate. Most people have no problem with the research itself, however the source of the stem cells (adult or human embryos) used in research is the primary cause of the debate. Some people feel that destroying an embryo is comparable to murder, even if the research it promotes may help people with serious illnesses. Other believe that an embryo is not a person and therefore research on an embryo is the same as research on any other group of cells.
This belief is wrong. Many countries including the United States have laws regarding embryonic stem cells. The United States has limits on when you can take embryos and there off course has to be consent from the donor of the stem cells. All these regulations are being met and the research is being done safely and in a way that always keeps safety as a first priority. New procedures and uses of stem cells also have to be deemed safe or the risks have to at least be shared before treatment can take place. These regulations make sure stem cells are being used in a safe way and that you know the facts about the way researchers are using
Opposing Viewpoints offers unbiased opinions on the future of embryonic research as well as how they have currently been used to cure many diseases. In addition, the article specifies how developing ethical standards to ensure that the use of embryos remains moral, allows for science to remain ethical. Many of the topics mentioned in this viewpoint consider bioethics and remain consistent throughout. Essentially, the purpose of this article was to establish a middle ground between ethics and science.
Stem cell research should be allowed on adults but not on humans. Only allowed on humans who are willing to be a part of the stem cell research but no one should be used against their own will. Embryos should not be used for embryonic stem cell research. An embryo being used for their stem cells and then discarded devalues that human life. This follows along the same unethical issue as abortion. When stem cells are removed from human embryos, a unique individual dies. However, if abortion is legal in the state that this research is conducted than research may be conducted on only aborted fetuses. That would be an...
