Recommended: Essay On The Adult Stem Cells
Stem cell research is one of the most widely expanding areas of scientific research being conducted all over the world today. In basic terms, stem cell research is the research of stem cells; however in actuality is much more complicated. A stem cell is a cell with the ability to develop into any of the cell types that make up the tissues and organs of the body. This makes these cells highly useful and provides endless opportunities in the field of regenerative medicine. There are two expansive lines of stem cell research, which involve multipotent stem cells and pluripotent stem cells. Multipotent stem cells are stem cells which can only specialise into cells of the same type of tissue, for example muscle stem cells can only become specialised muscle cells. This type of stem cell are known as adult stem cells and are found in the brain, muscles, skin, bone marrow and other fully developed parts of the body (see Appendix One for diagram). On the other hand, pluripotent stem cells can differentiate and specialise into any cell of the body (see Appendix Two for diagram). These are embryonic stem cells which are found in embryos that are five to seven days old. In 2006, Shinya Yamanaka, a scientist in Japan discovered that stem cells could also be generated from mature, fully specialised cells. These stem cells are known as induced pluripotent stem cells, and are reprogrammed so that they can mimic embryonic stem cells and become every type of cell. There is much difficulty in the research of adult stem cells, as they are hard to grow and differentiate under lab conditions, and there is still research being conducted with the induced pluripotent stem cells on the extent of their ability to differentiate, and whether they are still be... ... middle of paper ... ...[ONLINE] Available http://www.csa.com/discoveryguides/stemcell/overview.php (Accessed 30 March 2014) PBS – Religion and Ethics Newsweekly (2001) Religious Views on Stem Cell Research [ONLINE] Available http://www.pbs.org/wnet/religionandethics/2001/07/27/july-27-2001-religious-views-on-stem-cell-research/15307/ (Accessed 30 March 2014) ‘Stem cell’ (2014) World Book Encyclopedia, 2014 edn, Chicago, IL: World Book Inc. 18:889 Stem Cells Australia (2014) About Stem Cells [ONLINE] Available http://www.stemcellsaustralia.edu.au/About-Stem-Cells.aspx (Accessed 29 March 2014) Thomas, I.

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...
Stem cell research is a heavily debated topic that can stir trouble in even the tightest of Thanksgiving tables. The use cells found in the cells of embryos to replicate dead or dying cells is a truly baffling thought. To many, stem cell research has the potential to be Holy Grail of modern medicine. To many others, it is ultimately an unethical concept regardless of its capabilities. Due to how divided people are on the topic of stem cell research, its legality and acceptance are different everywhere. According to Utilitarianism, stem cell research should be permitted due to the amount of people it can save, however according to the Divine Command of Christianity, the means of collecting said stem cells are immoral and forbidden.
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.
Stem Cells are cells that scientist have began to try and use to help people. “In the mid 1800s it was discovered that cells were basically the building blocks of life and that some cells had the ability to produce other cells.” With the discovery of stem cells came the opening to a new area of development in what could be done with health and medicine of the world. Of course throughout history, stem cells have been a very heated subject between different groups of people who believe it is right or wrong. Some people believe that this form of research is against ethical or moral values. They too see this as being wrong because they view human embryos as a form of life. These cells are neutral cells that can be turned into any other one that is needed at the time. Stem cells can make more of themselves when they aren’t being used allowing them to be ready when something happens. In the human body, stem cells help repair the tissue that has been broken, torn, or lost. They help fix bones, heal abrasions, and even repair internal organs if needed. Scientist have the ability now to mani...
There are many different types of stem cells that are being looked at for research. These include embryonic stem cells, adult stem cells, and induced pluripotent cells. Embryonic stem cells are cells that have the potential to produce many different cells in the body. They are cells that are tak...

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).

Stem cell research has been a heated and highly controversial debate for over a decade, which explains why there have been so many articles on the issue. Like all debates, the issue is based on two different arguments: the scientific evolution and the political war against that evolution. The debate proves itself to be so controversial that is both supported and opposed by many different people, organizations, and religions. There are many “emotional images [that] have been wielded” in an attempt to persuade one side to convert to the other (Hirsen). The stem cell research debate, accompanied by different rhetoric used to argue dissimilar points, comes to life in two articles and a speech: “Should Human Cloning Be Allowed? Yes, Don’t Impede Medical Progress” by Virginia Postrel; “Should Human Cloning Be Allowed? No, It’s a Moral Monstrosity” by Eric Cohen and William Kristol; and “Remarks by Ron Reagan, Jr., to the 2004 Democratic National Convention” by Ron Reagan, Jr. Ethos, pathos, and logos are the main categories differentiating the two arguments.

Stem cell research is a topic that is discussed widely throughout our nation and can have many positive and negative outcomes. There are two different types of stem cells, embryonic stem cells and adult stem cells. Embryonic stem cells are able to differentiate and turn into other cells which are taken from an embryo at a few days old. An adult stem cell is a stem cell that resides in an individual, which can be used for repairing the tissue in which they reside. However, it has been proposed that embryonic stem cells and adult stem cells can either change or may be responsible for abnormal growth which could progress into cancer.
Throughout the past few decades, scientific discoveries in the medical world have advanced tremendously. One rapidly growing field is the use of human stem cells, which possess the capacity to divide and give rise to identical stem cells, and even to form new specific types of somatic tissue cells. The categorical term “stem cell” can be divided even further into two specific types: embryonic stem cells and adult stem cells. Embryonic stem cells are cells which can only be derived from preimplantation embryos, and have proven the ability to form cells of all tissue types; they are pluripotent. Alternatively, there are adult stem cells, which are undifferentiated and begin growing in the earliest stages of life and remain in the body forever.
Stem cells research can help the human with cancer, birth defects and help to build normal cells it is only normal that we should research stem cells. Stem cells are special cells that are undifferentiated and have the capability to become many other types of cells. All stem cells have the ability to renew, replicate, and divide; thus, producing new cells. These cells are separated into categories according to their potential to become other types of cells. Two main stem cell types are embryonic stem cells and adult stem cells. Embryonic stem cells come from four to five day old embryos. They can be found on the inside of the placenta. These stem cells are considered pluripotent, meaning that they can become almost all possible types of
