Stem Cell Information, Date retrieved: 20th September 2011. Obtaining adult stem cells, such as from bone marrow, can be painful. Though, it should not be taken lightly. The potential medical applications of stem cell therapy, particularly embryonic stem cell therapy, would appear to be endless and, once more, this fact is emphasized by those hoping to overcome political opposition to stem cell research. This can happen if stem cell research continues to expand and becomes better funded. Words: 4754 - Pages: 20. Stem cell research is a highly controversial topic that may possibly hold the cure for cancer and other diseases.
Embryonic stem cells are the embryoblasts derived from a blastocyst, embryo in an early stage of development after fertilization, which can turn into an organism. Words: 418 - Pages: 2. This hope was one that the late actor Christopher Reeve used as a platform for his activism. Of particular potential efficacy in medical research are the human embryonic stem cells. The important question to think about is Why the prospect of stem cell therapy has been greeted not as an innovation to be welcomed but as a threat to be resisted? Scientists have taken their time to get the full understanding of the principles of stem cell that relates to the long run self renewal of the cells. The possibility of stem cells to develop prospering health makes them beneficial to the human race. Animals subsequently received stem cells in the spinal cord.
Use our sample or order a custom written research paper from Paper Masters. Most of them are derived from those embryos that that grow from eggs that are fertilized in vitro and then taken for the purpose of research after gain the permission of the giver. Schaaf H, Streckbein P, Lendeckel S, Heidinger K, Görtz B, Bein G, et al. Stem cells come from many different areas in our body and they develop at different times throughout our lives. In some cases short term cloning was performed to allow for the creation and mining of stem cells; however, following the tests the cloned embryos were terminated Eve, Marty, McDermott, Klasko, Sanberg, 2008.
Umbilical cord stem cells are harvested with parental permission from umbilical cords after birth. Stem cell therapy is on the verge of being a revolutionary medical advancement in history. Stem cells have the ability to replace cells that are lost and can repair injured tissues. Blastocysts are 3 to 5 day old embryo. There are other types of stem cells like multipotent cells which are found in adult tissue like fat and embryonic stem cells which are from human embryos. July 8, 2008, from www. However, there is still a lot that need to be done in clinics and laboratory to offer to understand on how to utilize these cells for diseases treatment through cell based therapies.
Stem cell research is teaching us more about birth defects and how they can be prevented or possibly reversed. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. As far as studying the stem cells treatment continues, there can be found some practical disadvantages of using the stem cells for treatment. Although the reparative process appears to initiate following trauma to the brain, substantial recovery is rarely observed in adults, suggesting a lack of robustness. Many people say it is wrong based on the facts that it can use embryonic stem cells. They believe that embryos have the same rights against abuse as we do.
. As of this moment, no therapies in humans have ever been successfully carried out using embryonic stem cells. Blindness and vision impairment Since 2003, researchers have successfully transplanted corneal stem cells into damaged eyes to restore vision. Within the class of stem cells too there are present different types of stem cells. The embryos used in these studies were created for reproductive purposes through procedures. How to Write a Research Paper on Stem Cell Research This page is designed to show you how to write a research project on the topic you see to the left. Autologous stem cell-based treatments for ligament injury, tendon injury, osteoarthritis, osteochondrosis, and sub-chondral bone cysts have been commercially available to practicing veterinarians to treat horses since 2003 in the United States and since 2006 in the United Kingdom.
Stem cells, which owing to their property can be used stem cell therapy, can now offer the possibility of a renewable source of replacement cells and tissues to treat diseases including Alzheimers diseases, spinal cord injury, stroke, burns, osteoarthritis, heart disease, diabetes, and rheumatoid arthritis. Besides, it can be more related to some precise moments and report. When a stem cell divides, each new cell has the prospective of either remaining a stem cell or turning into a cell with more specialized functions for example muscles cells, red blood cells or brain cells. Biochem Biophys Res Commun 332:370-379. Nevertheless, unspecialized stem cells usually give rise to specialized stem cells such as blood cells, nerve cells, or heart muscle cells. In various organs like bone marrow and the gut, stem cells divide regularly to repair and replace damaged and worn out tissues in the body. Today, stem cell research is more open and accepted, due to technological advancements, but I think more importantly, a changing political mood.
This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs, although their use in people has been to date limited to eye-related disorders such as macular degeneration. The latest such development was in June 2005, when researchers at the Queen Victoria Hospital of Sussex, England were able to restore the sight of forty patients using the same technique. Embryonic stem cells are commonly cultivated from dropped fetuses or embryos springing from terminations, and can be made use of to provide life-saving treatments for lots of illness processes and health conditions. Stem cell therapy is also being used against certain types of cancer. Besides from graft-versus-host disease which have.
