What Are The Pros And Cons Of Encapsulated Cell T & T

Embryonic stem cell research is a highly debated and sensitive topic.  There is a lot of good that can come from researching this technology of stem cell research because many people all across the globe would benefit from it.  The United States will soon fall short while other countries are already using this advancement if we cannot come to a logical conclusion on this vital issue.

Stem cell derivatives may be a beneficial source of transplantable cells that may be able to repair and regenerate certain tissues. If this could be accomplished, the medical benefits would be enormous, such as helping Parkinson disease, MS, diabetes, and muscular dystrophies. Although, this could be an extremely important advancement in the field of medicine, there exist many ethical and religious issues that look down upon destroying embryos for research. The stem cells that are focused on in this report are embryonic stem cells. However, adult stem cells may also be used to give rise to lineages of cells that are more specialized than themselves. They are more differentiated than embryonic stem cells. Research using adult stem cells is much less controversial since they can be obtained without destroying an embryo. There is also a strong political aspect that has been brought up in recent discussions regarding groups who try to push adult stem cell research over embryonic stem cell research since they consider it a more permissible option. In contrast, people in favor of embryonic stem cell research try to discredit the potential of adult stem cell studies.

In humans adult stem cells, not embryonic stem cells, have been used in therapies for more than forty years. People with blood disorders have used stem cell therapy to take the opportunity to improve upon their life. On the other hand, embryonic stem cells have a very high potential to treat or even cure numerous diseases like diabetes and heart disease. They are much more versatile in their usage compared to adult stem cells. Another practical use for embryonic stem cells is to treat damaged nerves ("Testing The Use…”). These nerves could have been impaired in a spinal cord injury. As of today, scientists have already performed stem cell transplants in people whose cells were damaged through chemotherapy of disease.

. Embryonic stem cells have been identified by scientist as a type of stem cell that can advance regenerative medicine. The potential of regenerative medicine ranges from allowing pancreatic cells to produce insulin for diabetics to reconnecting the nerves in severed spinal cords. However, the greatest potential embryonic stem cells presents are its ability to change into any of the more than 200 different cell types in the body. This ability to change into any cell type can produce cures for Alzheimer’s disease, Parkinson’s disease, or any of the other conditions that stem cell therapy might help therefore improving the lives of those who live with these

Stem cell research is the future of medical and biological research and remedies, and it is fascinating to watch the progression of this new and important science as it unfolds. These cells were discovered in mouse embryos in the 1980s, and are remarkable because of their potential to grow into a variety of different kinds of cells within a body. Common in fetuses, and more rare in adult animals of all kinds, stem cells can be manipulated in useful ways to repair many tissues, dividing limitlessly for therapeutic purposes. When a stem cell divides, each new cell has the potential either to remain a stem cell or to differentiate into more specialized tissue, such as nerve, pancreas, bone marrow, or unique blood components. Initially

Researchers successfully attained embryonic stem cells from the embryos of mice in 1981, which led to the discovery of this process in human beings in 1998 (National Institutes of Health, 2001). Embryonic stem cells are derived from an in vitro embryo between five days and seven weeks. Regenerative medicine can benefit greatly from the characteristics of embryonic stem cells. This process enables damaged organs and tissues to heal themselves with the help of implanted stem cells matching the organ (Hunziker, 2010, p. 1). There are two traits

Adult stem cells are not necessarily derived from adult human but merely not from embryos. These stem cells can found in bone marrow, connective tissues, hair follicles, umbilical cords and other areas of the body. It is said that these cells have been used to treat an estimated 11,000 patients in the United States in the past two years alone, and over 70 diseases, including Parkinson’s and diabetes. (Pence, 2009) There have been 0 recorded successful treatments achieved by the use of embryonic stem cells. As well, stem cells from umbilical cord blood have been used to treat 65 diseases such as leukemia, and lymphoma. (Sweat,

This supports my claim because it shows that even if you are blind you can get damaged cell replaced by stem cells. Also it show that even with damaged eye cells they can be replaced because stem cells can be programed into any cell in the body.

stem cells were discovered a long ago that they can be beneficial for fighting against the killer diseases but after passing of two decades of the discovery it has been profound that (hESCs) are being tried as a treatment for two noteworthy illnesses: heart fail and type 1 diabetes.

While embryonic stem cells can restore and repair tissue, there also can be a risk when inducing them into

. However, embryonic stem cell research is also generally considered to have the greatest potential for delivering medical and scientific breakthroughs, since they are even more flexible (so to speak) and undifferentiated than adult stem cells (see Bongo and Richards).

Imagine an all-powerful miracle cure that could help treat devastating spinal injuries or eliminate the need for insulin injections. To some extent, one already exists. For years, researchers have been studying the miraculous potential of human embryonic stem cells. Human embryonic stem cells, also known as hESC, have the ability to develop into any kind of specialized cells in the human body, ranging from as simple as a skin cell to as complex as a neuron. This “miracle cure,” however, comes with a great cost; the stem cells have to be extracted from a human embryo, completely destroying it. Research institutions often obtain embryos either from abortion clinics or, most commonly, as a donation from a fertility clinic. Fertility clinics

Stem cells are undifferentiated cells that have the ability to become many different cell types by the process of mitosis and differentiation. Due to this unique property, many scientists are keen to researching and working with these cells. Furthermore, Stem cell is one of the most potential gates to curing diseases and developing new technologies.

Induced pluripotent stem cells were first reported in 2006 by two scientists in Japan. A Japanese patient was suffering from degenerative eye disease accepted therapy with using Induced Pluripotent Stem Cells in September. 2014. Although these cells have been approved use in undergoing human clinical trials, but there still are some disadvantages for using them compare with Human embryonic stem cell. For example, organ transplantation, because of human embryonic stem cells can become all types of cell in a specific area of organs, so these cells can develop, grow ，and repair the damaged organ. But they can only get from early embryo, and this way will have harm for the embryo, that’s why it is very hard to get and still has many limits for using them on therapies. Induced pluripotent stem cells come from adult stem cell through reprogramming to make them have similar functions as human embryonic stem cell. Otherwise, they can make from any cells by several steps, so it would be easier, but there is a problem that The ectopic transcription of Oct4 , Sox2 , Klf4 , and c–Myc can lead to neoplastic development from cells derived from iPSCs, because the expression of Oct4 , Sox2 , Klf4, and c–Myc genes is associated with the development of multiple tumors known in oncogene tics [22, 24]. Finally, when IPSC is transplant into the body, it may lead to increase the risk

Currently, stem cells are used to treat a few diseases, including the Stargardt’s macular dystrophy and leukemia. Stargardt’s disease is a genetic disease that may lead to the loss of vision. This is due to the degeneration of photoreceptive cells, the component in the retina of the eye that detects light. This disease is a result of a recessive mutation of a gene named ABCA4, which leads to the malfunction of membrane proteins that are responsible for the active transport in retina cells. By using embryonic stem cells, scientists are able to develop retina cells which are then injected into the eye of the patient. Theoretically, the cells will attach themselves to the retina and stay, which ultimately improves the vision of the patient. This
