Name: October 16th 2012 Stem Cell Research Stem cells are those biological cells that are found in creatures, which are multi cellular and these can split and separate into a varied number of specialized cell types, which can restore themselves to produce more cells of this type…
However, in an embryo that is developing, stem cells can differentiate into a large number of specialized cells and may maintain the normal output of those organs, which regenerate such as blood and skin. The main difference between stem cells and other cells in the body is the fact that they are able to differentiate into other types of cells or tissues. This ability allows them to replace the cells that have died, moreover, this has been used by scientists to replace those cells that are defective in patients who have diseases and effects that cannot be effectively cured by other forms of medicine (Dresser 181). “Scientists believe that stem cells, from which all other types of cells can grow, will help cure Alzheimer's disease, Parkinson's disease, diabetes, spinal injuries, congestive heart failure and other maladies” (Kelley). The usage of stem cells, especially embryonic stem cells in the cure of diseases such as Parkinson’s disease has come to breed a lot of controversy, and there has been a great deal of support for those who are for it and for those who are against it. There are different types of stem cells andmany different terms have been used to describe them, and these descriptions tend to come from the area of the body or the state of development from which they have come. Among the different stem cell forms are the following: tissue stem cells, fetal stem cells, cord blood stem cells, embryonic stem cells and finally, induced pluripotent stem cells. Moreover, many adult stem cells can substitute cells that die or restore tissues that have been damaged in injuries and such adult tissues as skin and muscle have their own stem cells, and in the bone marrow, blood-forming stem cells help in the production of blood cells. It is yet to be determined whether all organs have stem cells and it can, therefore, be said that the term adult stem cells is used very broadly and may contain other categories of stem cells, which are not necessarily found in adults. There are certain accepted stem cell therapies in the medical field, which require the use of stem cells, which are tissue specific. These tissue stemcells used in these therapies include the bone marrow and cord blood stem cell transplantation, which treat diseases related to blood or the restoration of blood after treatments of such conditions as cancer. In this situation, the tissue stem cells are used to mend the parts of the body from which these cells came. Another adult stem cell type is the mesenchymal stem cells, which are found in a number of tissues, and they are speculated to be able to produce bone, cartilage, and fat (Siegel 215). This has yet to be proven for human beings, but there is ongoing research on animals to determine whether these cells can be used to treat such conditions as bone fractures that do not normally heal. In addition, there is a possibility that these cells or cells that are similar to them play a role in altering the immune system in response to injury. Fetal stem cells are those, whichare taken from the fetus, which is a developing baby that has gone approximately ten weeks into gestation. The majority of the tissues in the fetus include cells that can help in the swift growth and maturity of organs and are extremely much like adult stem cells, which are often tissue specific. The fetus stem cells often produce the cell types that are mature inside the organ from which they were ...

In that aspect, this paper is going to present in-depth research on stem cells and facts surrounding the stem cells. The paper will also analyze legal views of various countries concerning the stem-cell research. In addition, the paper will analyze various controversies that surround the stem-cell research alongside advantages and disadvantages of adopting stem cell research in the contemporary societies.
Stem cell research is particularly useful for patients suffering from hemophilia. Hemophilia is very complicated and stem cell research helps in curing it, there are other blood related diseases which can also be cured using stem cells this goes to show that we have made tremendous progress in the field of science and research.
The origin and development of stem cell research has elicited different reactions from many quarters. It has come to be known over the years as the stem cell research controversy. Many people do not agree with the research carried out on different organism cells (Pollack, 2012).
Many are relying on stem cells as a new miracle medicine and a “great hope”. (Khan 2008) Which ever stance one may take regarding stem cells and whether or not research is morally worth it is important to consider when forming an opinion. With stem cells it is important to look at facts regarding stem cell research.
Advocates for stem cell research highlight its benefits and they support the laws which have been suggested in its favor. Others are however not highly enthusiastic about its application within the current health system. As a result, many laws and versions of stem cell research legislation have been suggested throughout the years.
In addition, the paper will analyze various controversies that surround the issue of stem-cell research and analyze the merits and demerits of stem-cell research. The paper will conclude with an elaborate conclusion bearing personal view with regard to the stem-cell research.
It was in the year 1998 that the University of Wisconsin scientists developed the first human embryonic stem cell lines. The medical field is eager to explore this field because of the possibility of generating replacement tissues for cells and organs that are not functioning.
Stem cell research began during the 19th century when it was found that certain cells in the body had the potential to transform into other cells and by the early 20th century greater research was being carried out on these potential cells. Stem cell research have been conducted on human as well as animal cells, and in general, stem cells are of 3 types namely, totipotent cells, pluripotent cells and multipotent cells.
Science and technology has developed so much that in the recent years scientists hope to use these cells to develop new tissues, treatments and potentially even organs for transplanting into a patient. First and foremost argument made by the scientific community is that human stem cell research is said to promise new life changing treatments and possible cures for many devastating diseases and injuries, such as Parkinson's disease, diabetes, heart disease, multiple sclerosis, burns and spinal cord injuries (Young 2-16).
