Human Embryonic Stem Cells ( Hescs ) - 1627 Words

Introduction Vision loss has raised tremendous attention along with the ageing society. Relevant health expenditure has been invested into the medical field to improve patient’s quality of life, yet the (cure. the invention of iPSC, provide opportunity) MORE! Establishment of iPSC The interest in developing human embryonic stem cells (hESCs) as a regenerative medicine has been prospering due to its pluripotency and indefinite self-renewal capacity since first discovered in 19981,2. However, the method to harvest hESCs by destroying embryos raised ethical concerns and thus the progress of this therapeutics has been impeded for years. Alternative approach was not achieved until the discover of induced pluripotent stem cells (iPSCs) by integrating a combination of transcriptional factors (Oct4, Sox2, Klf4, and c-Myc) to human fibroblasts through retroviral vectors3,4. The research of iPSCs has grew rapidly since then due to its avoidance of embryo utility as well as its capacity to encapsulate disease phenotype, which is ideal for cell-based disease modelling and drug screening1,4. Furthermore, autologous iPSCs give possibility to non-immunogenic transplantation and thus provide promise to patient-specific therapy1. To realise clinical application of iPSC therapy, several new methods to produce iPSCs were developed using non-integrating approach such as recombinant proteins, Sendai virus, mRNA, and episomes1. The new lines of iPSCs eschew the risk of tumorigenicityShow MoreRelatedEmbryonic Stem Cells Pros And Cons1664 Words   |  7 Pagesone 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 â€Å"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 fromRead MoreAdvantages Of Human Embryonic Stem Cells1572 Words   |  7 PagesCompare advantages and disadvantages of human embryonic stem cells (hESC) for use in cellular therapy The research of human embryonic stem cells (hESC) is talked about a lot in the field of medical research, not just by the scientists, but also by politicians, religious groups, etc. The discovery of stem cells is known as a medical sensation, with its research having the potential to cure many diseases. But there are still ethical issues standing in the way of this research, and due to this, differentRead MoreHow Does Embryonic Stem Cells Help Treat Patients With Spinal Cord Injuries?1228 Words   |  5 Pagesapplied is the use of embryonic stem cells to help treat patients with spinal cord injuries. Embryonic Stem Cells (ESCs), as their name suggest, are derived from the inner cell mass from an early stage, pre-implantation embryo, known as a blastocyst, from eggs which have been fertilized via in vitro fertilisation (IVF). Once consent has been given by the host, these pluripotent stem cells are then cultured and donated for research purposes. The Human Embryonic Stem Cells, (h ESCs) serve a multitudeRead MoreThe Ethics Of Embryonic Stem Cell Research1520 Words   |  7 PagesAmerican Government 16 December 2014 The Ethics of Embryonic Stem Cell Research In the 21st century, disease is rampant and for most diseases, we have no cure because we haven t researched them long enough to find a specialized cure. One option that we have is human embryonic stem cell (HESC) research. HESC research consists of using human embryonic stem cells, which are very flexible and adaptive to create the necessary cells to develop future cell-based therapies for currently untreatable diseasesRead MoreStem Cells And The Human Body1421 Words   |  6 Pages Stem Cells Raven Carr Governor State University Stem Cells The human body is full of hundreds of special types of cells that are essential for ones every day health. These special cells are accountable for keeping our bodies going daily for instance making our brains think, hearts beat and, restoring our skin cells as they shed off. Stem cells are the provider for the development of new cells. â€Å"Stem cells have the amazing potential to expand into many different cell types in the body during earlyRead MoreStem Cells : Growing An Ethical Pair1427 Words   |  6 PagesStem Cells: Growing an ethical pair What if millions of Americans could have their lives changed for the better? This could be a reality if human embryonic stem cells research (HESC) was regulated and funded by the government. The reason for the lack of human trials is that many believe the use of stem cells is unethical. This combined with the fact that the process is extremely expensive, and it goes against many people’s religious or morals beliefs. Thankfully, under President Obama, the restrictionsRead MoreStem Cell Research1167 Words   |  5 Pages. Stem cell is a cell that has the ability to change into several or multiple types of cells or into any cell type in the body. There are two main types of stem cells, adult stem cells and embryonic stem cells. Embryonic stem cells are found in cells that have only undergone the first few dozen cycles of growth and division following the fusion of egg and sperm. These cells are pluripotent and can be maintained so that they grow and divide indefinitely witho ut differentiating. Likewise, theyRead MoreHeart Disease : The Leading Cause Of Years Of Life Lost Globally Essay1229 Words   |  5 Pagesregenerating cardiac muscle cells, also known as cardiomyocytes that were killed in previous heart attacks by using stem cells to replace the damaged heart tissue. First and foremost, ischaemic heart disease is a condition in which blood flow and oxygen is restricted in the heart which can lead to heart attacks. When cardiac muscles are starved of oxygen and nutrients, they will die resulting in scarring since cardiac muscles are one of the least regenerative tissues in the human body. Scarring can eventuallyRead MoreThe Conflict Between Medical Potential And Ethical Objections1358 Words   |  6 Pages Stem Cell Research: A Conflict Between Medical Potential and Ethical Objections In 2011, 23 year old Katie Sharify was involved in an automobile accident that damaged her spine, leaving her paralyzed from the chest down. Katie’s medical team proposed an experimental approach to her therapy using stem cell research, in which stem cells taken from a 5 day old embryo could be converted into cells used for communication between the brain and body. Seeing the glimmer of hope, Katie accepted.

I chose to base my research around the question, Should embryonic stem cell research be government funded? When I finish highschool I hope to pursue a career in the medical field. Although I wish to become a doctor and may not be directly researching stem cells, they may one day be a treatment that I will have to administer to patients. To answer this question
