Introduction Human embryonic stem cells (hES cells) are currently discussed not only by the biologists by whom they were discovered but also by the medical profession‚ media‚ ethicists‚ governments and politicians. There are several reasons for this. On the one hand‚ these ‘super cells’ have a major clinical potential in tissue repair‚ with their proponents believing that they represent the future relief or cure of a wide range of common disabilities; replacement of defective cells in a patient by transplantation

difference between embryonic stem cells and adult stem cells is that an embryonic stem cell is not fully developed and with no specific cell tissues. Embryonic stem cells are found in the inner cells mass of the early embryo. The very first embryonic stem cells are totipotent (can be able to create all kinds of cells) but the rest after that are pluripotent which means that it can create many different types of cells such as white blood cells‚ nerve cells‚ and neurons. Adult stem cells are less flexible

Johns Hopkins University] had isolated fairly potent stem cells from early human embryos and grown them in a culture (Harkin‚ Frist‚ Skirboll‚ and West).” Embryonic stem cells are derived from the earliest human embryos which are developed from eggs that have been fertilized in vitro at fertility clinics. They can migrate to the site of infection or damage in the body and transform into any kind of cell that will fight it off. With the research that James Thomson and John Gearhart did‚ the scientific

Embryonic stem cells help treat tough diseases that our bodies attracted‚ and can not fight off. If we continue to use embryonic stem cells then the treatment for these tough diseases will be more efficient. “ Stem cells are expected to be most useful in treating tough diseases.(those that arise from problems with various genes‚ and are often related to environmental causes)” (Pearson). This information is saying that embryonic stem cells are more useful than any other stem cells because they are

One of the most controversial debates in recent history has been the human embryonic stem cell debate. Millions and millions of embryos are not used each year when they could very well lead to a cure for fatal diseases such as leukemia and cancer. As well as become a cure for neurological diseases like Alzheimer’s disease and Parkinson’s disease. Human embryonic stem cell research has enormous potential to cure many diseases and change the face of modern medicine. However‚ there is much debate

extracting the stem cells from the embryo. The only way to obtain the cells is by destroying the embryo‚ placing the moral status of an embryo into question. This research plays with two important principles: “the duty to prevent or alleviate suffering‚ and the duty to respect the value of human life” (Hug 108). Embryonic stem cell research poses an unruly question that places one in a position where one principle is of higher value than the other. There is not a global consensus to what should be done

fertilized egg cell divides millions of times to form the approximately six billion cells that make up the human body. These types of cells (4 to 7 day old embryo) are called embryonic stem cells that are unspecialized and have the ability to renew themselves and give rise to specialized cell types (they have not yet developed into cells that perform a specific function). A stem cell is uncommitted and remains that way‚ until it receives a signal to develop into a specialized cell‚ unlike a heart

Pros: Embryotic stem cells could cure numerous diseases‚ and provide organs to people on the transplant list. Because of the high demand of organs‚ innumerable people die waiting for a transplant. If scientist discover how to create organs‚ lives will be saved. There is research that shows that it could be possible to use the patient’s own cells instead of embryonic stem cells. Cons: There are concerns with obtaining stem cells. Stem cells are acquired from human embryo or fetus‚ and can cause birth

to lift certain limitations on federal funding for embryonic stem cell research (“Embryos and Unintended Consequences”). In 1973‚ the United States legalized abortion with the landmark supreme court case Roe vs. Wade. According to The Michael J. Fox Foundation for Parkinson’s Research‚ stems cells are‚ “a renewable source of tissue that can be coaxed to become different cell types of the body.” Embryonic stem cells in particular are‚ “stem cells derived from embryos that develop from eggs that have

Embryonic stem cells are stem cells that come from inner mass cells of a human embryo that are undifferentiated. They are a new and innovative way to help people of society‚ and with all innovative ideas comes controversy. Some people believe that embryonic stem cells should not be researched or toyed with‚ while others are all for it. Embryonic stem cell research is a positive thing that can enhance the world in several ways. It can boost the economy‚ save the lives of many people‚ and not offend
