• Essay on stem cells

  ...Stem cells are unique because they have the ability to generate new cells of any kind during early life and growth. There are about 200 different types of cells in the body; such as muscle, skin and brain cells. Most of these cells have to be repaired or replaced once in a while. For example our taste buds are replaced every 10 days, skin cells every couple of weeks and liver cells every 300-500 days. Stem cells serve as an internal repair system dividing essentially without limit to replenish other cells. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division. Second, under experimental conditions, they can be induced to become tissue or organ specific cells with special functions. Unlike muscle cells, blood cells or nerve cells which do not...

• stem cells Essay

  ... Stem cell research has been in the media since the day it was discovered. With the potential to cure many patients who are otherwise bound to die of diseases that are currently incurable, of course stem cells would be a big deal. But there are people who believe that stem cell research is a very inhuman and immoral act only because embryonic stem cells come from unborn embryos. Even within developed nations, research of stem cells is illegal because of this. These nations ignore a stem cell’s potential to cure lives; rather they focus on the source of stem cells. However, not every nation has a ban on stem cell research. Brazil, for example, completely allows stem cells to be researched on and cultivated from embryos because they understand that stem cells are the future of medicine. Contrastingly, Italy and Germany strictly forbid the creation and use of embryonic stem cells. But in a country like the US, the stem cell research policies are different because though it allows stem cell research it do does not allow any sort of federal funding for it. One could say that the US is sitting on the fence concerning...

  ... Stem Cell Research From the Viewpoint of Dr. Gamal Serour Anatomy & Physiology 11 September 2013 Anatomy & Physiology 11 September 2013 I am Dr. Gamal Serour, I am of the Muslim ethnicity. I am a Professor at Al-Azhar University and Consultant in Obstetrics and Gynecology, specializing in infertility treatment. Also the director of the international Islamic Center for Population studies and Research. I believe the study of the stem cell research can be used to help the human race. Instead of leaving stem cells to perish, why not use them for research for the benefit of human beings. In Islamic culture we tend to favor stem cell research because Islamic law believe ensoulment of the embryo only occurs on a certain day of the pregnancy, and that is the point when the baby gains moral status and rights as a legal person. I believe that stem cell research has the potential to promote human healing. “Some ‘pro-lifers’ or pro-life organizations regard the destruction of the blastocyst, which is a laboratory-fertilized human egg, to be the murder of human life. They believe that life begins at conception.” They also argue that stem cell research is killing potential innocent babies during the study of stem cell research because it...

  ...Biology 103 Stem cells are known as the foundation of our bodies, and without them we would be unable to repair various organs or tissues whenever they may become damaged. Stem cells are very extraordinary cells because after division and a new cell is created, they are able to either remain a stem cell or turn into an even more specialized cell such as a muscle cell, red blood cell, or brain cell. Until recently, there were only two major types of stem cells, known as embryonic stem cells and adult stem cells. More recently, scientists have been able to create induced pluripotent stem (iPS) cells. Human embryonic cells were first isolated and cultured in 1998, and scientists have made noteworthy progress ever since. Embryonic stem cells are acquired from embryos, which are multicellular diploid eukaryotes in their earliest stages of life. In humans, it is called an embryo until eight weeks after fertilization, and then known as a fetus. These cells are retrieved in human forms in an early stage of the development process, known as the blastocyst stage. The blastocyst is the inner cell mass of an embryo that is...

  ... STEM CELLS Where are stem cells sourced from? Stem cells are sourced from three main sources, Embryos, bone marrow and umbilical cord blood. Each different sources’ Stem Cells are either totipotent, pluripotent or multipotent. Refer to Figure 1 Figure 1 Stem Cells can be categorised into their capability of being cultured into a different cell. Embryonic Stem Cells: Are pluripotent cells meaning they can be cultured into most cell types. The Embryonic Cells are sourced from in the internal cell mass of a blastocyst, meaning that the embryo (encloses all the stem cells) has increased in its size and has transformed into a cluster of smaller balls. The Stem cells are then taken out from the internal cell mass of the blastocyst. Then it is cultured in the lab. This usually take s 5-7 days to go through this process. Because of the embryonic cells pluripotent nature it can be transformed into quite a few different cell varieties such as Nerve Cells, Muscle cells, Red Blood Cells and Whole Organs. Stomatic Stem Cells: They are multipotent and are commonly known as adult...

  ... Stem cells agreement by Zayne Burnham Many scientists are now researching special types of cells called stem cells. Stem cells are very important and have the potential to cure many diseases; however there are also many issues to consider when using stem cells. Stem cells research has created concern for some in the community, national and international.beacause the best source of stem cells is growing human embryo. The dilemma is that the growing embryo is the earliest stage of human life extracting the stem cells destroys the embryo and so a potential life is ended. What is a stem cell? A stem cell is special cell in the earliest stages of human life stem cells can divide to produce all the different specialised cells of the body. After birth as we grow the number of stem cells in our bodies decreases. The stem cells left in adults can usually only grows into certain types of cells. Adult stem cells only repair injuries to damaged tissue or broken bones as adult bodies have finished growing. The single fertilised egg in no way resembles a human but...

  ...notable advancements has been the use of stem cells to regenerate tissue in the body and cure disease such as Type I diabetes. While stem cell research is still in its infancy it represents one of the most important tools for the future development of biological science.[i] Considering the advantages of stem cell research, experts in the field have noted that this process of stem cell research enables biomedical professionals to develop treatments and possible cures for degenerative diseases such as Alzheimer’s, Parkinson’s and diabetes.[ii] This is because when stem cells are harvested from either the embryo or the adult they can be programmed to become any cell or tissue in the body. Thus, for patients with Type I diabetes that have no insulin producing cells in their pancreas, these cells can be grown in the laboratory and transplanted in the patient with the hope that these cells will produce insulin and cure the individual suffering with this disease. The same type of theory regarding the treatment of other degenerative disease has been proposed.[iii] Despite the fact that stem cell research appears to hold the promise for improving the lives of millions of individuals with debilitating diseases, controversy over the practice has made...
