“Embryonic stem cell research offers both great promise and great peril.”
- President George W. Bush, Aug. 9, 2001
Stem cell research is not new but only recently has it become widely known to the public because the benefits of the technology are coming closer to reality; the field of stem cell biology is advancing at an incredible pace with new discoveries being reported in scientific literature on a weekly basis. Scientists first announced a method of growing embryonic stem cells in a laboratory in 1981, but the cells were from a mouse. It wasn’t until five years ago that James Thomson (pictured to the leftP3) at the University of Wisconsin- Madison announced that he was able to isolate cells from the blastocyst of an early embryo.5 From research he gathered in the fields of applied reproductive biology and mouse embryology, he was able to develop the first human embryonic stem cell lines. At the same time as Mr. Thomson, John Gearhart (pictured to the rightP4)reported the first derivation of human embryonic germ cells from the primordial germ cells located inside the fetal gonadal tissue that is key in the development of eggs and sperm. Dr. Gearhart, working at Johns Hopkins University with other prominent stem cell researchers, was then able to develop pluripotent stem cell lines by isolating stem cells from early human embryos and grow them in culture. Most recent research is focusing on two types of stem cells: pluripotent cells and adult stem cells that have been in clinical use for use but just recently were discovered to be able to develop into cells that have many of the characteristics of neurons. But even with all the information known alrea...

- We have known the amazing benefits of human tissue in medical research. These cells have helped with some of the most important advances in the sciences. They are used to develop vaccines for rabies, smallpox, and measles or used for radiation, drugs, cosmetics and viruses research which launched a million dollar industry [ Skloot, 316]. They have been used to find the cure for multibillion people, including most of us today. However, not that many people know where are these tissues come from or the stories of the “donors” who were desperate to protect their bodily rights and property rights....

- Over the past decade scientist and the U.S government have been debating about funds for stem cell research (SCR), the amount spent depends on who is in office. The Democratic Party fully supports SCR, but the Republican Party somewhat opposes the concept of SCR, arfuing it violates the Christian principle of life. As a result, this topic is considered controversial, but also beneficial if allowed. Despite the controversy, SCR should be well funded for medicinal use, because blank stem cells (SC) can be used to regenerate bones and muscle tissue, they can be used to control or even reverse neurodegenerative disease, and because they can be used for therapeutic cloning....

- In the 2004 presidential election, one of the most controversial issues facing voters was the battle over embryonic stem cell research. In the weeks leading up to the election, polls were indicating that 47 percent of Bush supporters agreed that the destruction of embryo cells is unethical; however, 53 percent of Bush voters supported stem cell research. The overwhelming majority of Kerry backers also supported stem cell research, indicating that the majority of American voters support stem cell research.... [tags: Ethics]

- Genetic Engineering: Humanities Saving Grace or the End of the Human Race. This is the first time history that humans can directly manipulate an organism’s genome to our own benefit. The first genetically modified organism, or GMO, was created in the seventies and has led to GM crops and GM medical treatments. The whole ideology is not new to humans. Artificial selection bred well mannered wolves into man’s best friend. And yet, the controversy has only arisen in the past decade or so. Those who support this specie of scientific advancement and those who wish to uphold their organic roots are butting heads with more passion than ever.... [tags: dna, cells, GMO]

- Research which involves human participants who undergo uncomfortable circumstances can raise moral, social, and political concerns (Schwartz, 2001). This ensues a whole new field of research known simply as research ethics. Research ethics is generally interested in the analysis of ethical matters that arise when people are used as subjects in such studies. Research ethics requires the application of necessary ethical convention to a variety of topics involving any scientific study. There are quite a number of experiments brought to what is known as the Internal Review Board.... [tags: Research Ethics ]

- In general, a cell can be defined as a stem cell if two basic criteria are met. First, stem cell is capable of self renewal for indefinite period throughout life while maintaining undifferentiated state, i.e., the cell can divide and produce two identical daughter cells and thereby maintains the stem cell pool. Second, stem cell possesses capacity for differentiate into specialised and functional progeny under the right conditions, or given the right signals. It may divide asymmetrically to yield an identical cell and a daughter cell that acquires a particular cell type’s properties, such as morphology, phenotype and functional physiology that classified it belongs to a particular tissue (Bu...

- In the first ten days after conception, several hundred stem cells already multiplied and a baby will be formed. These tiny stem cells produced osteocystes, cardiac muscle cells, and neurons. They are the building block for all 260 types of cells in our bodies. Even through adulthood, stem cells are produced by our bodies to replace old cells. However, we do not produce enough stem cells to heal a spinal cord injury or fight cancerous cells. Through research, scientist can manipulate embryonic stem cells that would treat autoimmune diseases, heart diseases, spinal cord injuries, and much more....

- Gene expression is the ability of a gene to produce a biologically active protein. This process is regulated by the cells of an organism, it is very important to the survival of organisms at all levels. This is much more complex in eukaryotes than in prokaryotes. A major difference is the presence in eukaryotes of a nuclear membrane, which prevents the simultaneous transcription and translation that occurs in prokaryotes. Initiation of protein transcription is started by RNA polymerase. The activity of RNA polymerase is regulated by interaction with regulatory proteins; these proteins can act both positively, as activators, and negatively as repressors....

- There should be a call for stricter regulation of post-mortem human tissue. It would seem obvious that what is of paramount value in life would necessarily depreciate in death. This in not true of the human body. With the emergence of biotechnology and the consequent need for post-mortem human tissue, the human cadaver has become quite valuable. In pieces and parts or in its entirety, organizations will pay top dollar for the human body, even after it houses the human spirit. Throughout history, civilizations have found uses for the bodies, organs and tissue of the dead.... [tags: Medical Ethics ]

- While some people might say that stem cell research is immoral and unethical, others believe that it is a magical solution for almost any problem, thus leading to a very controversial issue. Scientists have been searching for years for ways to eradicate incurable diseases and perform other medical procedures that yesterday's technology would not fix. With the rapidly arising, positive research on stem cell technology, the potential that exists to restore any deficiency is in the same way, likely to destroy humanity.... [tags: Ethics]
