Advantages Of Human Embryonic Stem Cells - 1572 Words

Compare 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, different parts of the world have different rules and regulations regarding the research of stem cells and their use in cellular therapy, and it is even illegal in a number of countries. Before I dive straight into the advantages and disadvantages of their use in cellular therapy, I should talk about the basics of hESC and how we can make them. Embryonic stem cells are pluripotent, i.e. they can differentiate into any type of cell in our body, and they can replicate indefinitely. We can create an embryonic stem cell line in more than one method, and most of them involve creating a fertilized egg (zygote), which eventually forms into a blastocyst. The inner cell mass of the blastocyst can be transferred onto a petri-dish containing a culture medium, where it is encouraged to divide. The diagram below illustrates this process. (copied from Gepstein 2002) Another method would be by a process known as Somatic cell nuclear transfer (SCNT), which is sometimes referred to asShow MoreRelated Stem Cell Research Essay example988 Words   |  4 PagesStem Cell Research Stem cells are a large focus of study in todays biomedical world. Stem cell research offers the hope of transplants being done without the sacrifice of another person losing an organ. There are many different pros and cons when it comes to discussing the use of stem cells. In order to develop an opinion of whether or not stem cells should be used, one must first understand what they are and how they are used. ?Stem cells have the remarkable potential to developRead MoreStem Cells And Stem Cell Research1477 Words   |  6 Pagessociety is that of stem cells. Stem cells are the cells in the early human developmental stage that form to be any type of cell. Not only do these cells have the ability to transform, but they also act as the body’s repair system. With this knowledge, the scientific community has used these traits to help cure diseases and even save lives. However, there is a problem using stem cells for research. There are two kinds of stem cells that exist, Somatic stem cells and embryonic stem cells. The firstRead MoreEssay about Alternatives to Human-embryo Stem-cell Research1145 Words   |  5 Pagesto Human-embryo Stem-cell Research      Ã‚   This essay counters the media and many scientists claims that there are no viable alternatives to human-embryo stem-cell research (ESCR).    The media restate the claim (made repeatedly in NIH documents) that adult stem cells do not have the same potential as embryonic stem cells, which in theory can form any tissue. But studies done with adult stem cells (studies which mirror the ones done with embryonic stem cells) show that adult stem cellsRead MoreThe Debate Over Embryonic Stem Cell Research1710 Words   |  7 PagesEmbryonic Stem Cell Research Embryonic stem cells, according to the National Institute of Health, are cells obtained from embryos that are prepared from fertilized eggs which have been collected through the in vitro technique; in specialized clinics. Scientists use the stem cell research to have a better idea about the evolution, aging, and disease. Thus, they keep track of the stem cells progress across the lifetime; this tracking process can help scientists to figure out the genetic mutationsRead MoreStem Cell Research Debate1119 Words   |  4 Pagesï » ¿Stem Cell Research Debate There are only a small number of issues that are controversial as far as the public, the government and scientists are concerned. The father of all issues, however, is the debate that revolves around the ethics of stem cell research. Stem cells can be defined as those cells in an embryo that essentially give rise to the entire organism (Capra, 1999). In the contemporary world of today, the issue of embryonic stem cell research is one of this controversial significantRead MoreThe For An Anonymous Donor Program985 Words   |  4 PagesAdditionally, while there are solutions to the organ shortage problem, there are also alternative solutions. The first alternative solution is to establish an anonymous donor program, where organs are donated and received from complete strangers. An advantage to an anonymous donor program would be that, it would eliminate the social bias and the medical bias. On the other hand, a disadvantage would be that, the recipient of the organ would know nothing about the donor. That could present issues forRead MoreThe Human Of Human Cells984 Words   |  4 PagesHealth, Human Embryonic Cells are cells that can replicate and do not change as they divide from their parents. Human Embryonic Cells are born as cells without a specific purpose, however, they have the ability to become any type of cell in one ’s body. Embryonic cells are grown in laboratories taking eggs and sperms donated by people and fertilizing them in a process called In Vitro Fertilization. Once an egg is fertilized by sperm, the zygote turns into an embryo, which is where this cells are foundRead MoreThe Advantages and Disadvantages of Stem Cell Research Essay1197 Words   |  5 Pagescontroversy regarding the bioethical issues of stem cells and the pros/cons of its research. In order to understand the clash of opposing opinions on stem cells, it is important to know the root of stem cells, as well as their functions and scientific findings. â€Å"Stem Cells are very essential to develop organisms. They are non-specialized cells which have the potential to create other types of specific cells, such as blood, brain, tissue or muscle cells† (Experiment Resources, 2008). In addition, injuriesRead MoreStem Cell Type Is Best?1264 Words   |  6 PagesTopic: Stem research, which stem cell type is bes t? Umbilical cord stem cells or embryonic stem cells. General Purpose: To inform Specific Purpose: To inform the audience of the advantages and disadvantage of using embryonic and umbilical cord stem cells in research. Central Ideal: While medical researchers believe that the use of embryonic stem cells is their best option in research, others believe it to be unethical and immoral, and that umbilical stem cells are a good alternative to embryonicRead MoreStem Cell Research : Stem Cells1416 Words   |  6 PagesSTEM CELLS In this report, I mainly focused on Stem-Cells. You will read about Stem-Cells and its history from the moment this term was known. Also, you will know the Sources, properties, and the types of Stem-Cells. In addition, you will know some of the pros and cons researches about Stem-Cells. Stem-Cells are cells that have the ability to divide and multiply and renew itself. †¢ Sources of Stem-Cells: 1- The first source is Bone Marrow. 2- The second source is
