Overview Of Embryonic Stem Cells - 771 Words

Stem cells play a fundamental role during all stages of development and have the potential to study and treat disease (Spitalieri et al., 2016). Embryonic stem cells (ESC) are pluripotent cells that emerge from the inner cell mass of the blastocyst and can give rise to various cell types (Liang and Zhang, 2013). Induced pluripotent stem cells (iPSC) have similar characteristics but are derived from adult differentiated somatic tissue (Liang and Zhang, 2013). This review will briefly compare ESC and iPSC in the context of cell therapy and disease modeling. The human ESCs have long been considered the gold standard for modeling disease and have served as the basis for developing cell therapies (Spitalieri et al., 2016). However, the use of†¦show more content†¦That is, ESC line are often exposed to fetal bovine serum or other animal-based media for culturing purposes (Desai et al., 2015). This increases the likelihood of activating the immune response and tissue rejection. It is, therefore, necessary for some receipts of ESC to take immunosuppressants and mitigate the immune response (Odorico et al., 2001). In recent years, researchers have developed ESC parthenogenetic lines that could provide HLA histocompatibility for the majority of a given population (Revazova et al., 2008). Moreover, ESC lines are currently being cultivated in systems that are free of animal contamination (Fu et al., 2010). Such improvements could advance the clinical application of hESC for the treatment of disease. Furthermore, iPSCs are in theory more ideal than ESCs for the modeling of disease due to two reasons. First, iPSC can capture the genotype of a particular individual and reproduce the severity of a disease (Acab and Muotri, 2015) Second, iPSC can take into account variations within different ethnic groups (Merkle and Eggan, 2013). This is not easily achieved in human ESC lines, which have thus far had limited success in modeling complex disease. In contrast, iPSCs can more closely recapitulate the genetic hallmarks of a disease (Acab and Muotri, 2015). This may prove beneficial for toxicity-testing and development of new drugs for the treatment of disease (Pappas and Yang, 2008). Nonetheless, iPSCs suffer fromShow MoreRelatedThe Debate Over Stem Cell Research1685 Words   |  7 PagesWhile the use of stem cells can offer a lot to the scientific community, the derivation of stem cells from embryos is ethically unacceptable; and the use of stem cells in humans should be completely prohibited. Since the first research on embryo stem cells in 1998 on mice the controversy has been relentless (Timeline), and even now, scientists have made great strides in waning off of embryonic stem cells and instead using induced pluripotent stem cells from adults, however these have their issuesRead MoreHuman Embryonic Stem Cell Research1313 Words   |  6 PagesJessica Rogers Kendra Gallos English III Honors 18 April 2016 Human Embryonic Stem Cell Research Human Embryonic Stem Cell Research, or HES cell research, is a very controversial ethical debate. This issues is a dilemma for scientist, religious activist, and many more. HES cell research is being disputed because the practice is morally wrong. The other side of the issue stands with many scientist, being that they see the potential lives it could save in the long run. Religious activist, andRead MoreEssay about Human Embryo Research 1019 Words   |  5 Pagesequal. The same law should be enforced concerning human embryonic stem cell research. Dr. James A. Thomson discovered stem cells in 1998 and they’ve intrigued scientist ever since. The stem cells themselves are derived from a three to four day old cluster of cells called a blastocyst and they are so coveted because they are pluripotent, meaning they can differentiate into any type of cell in the human body. Although embryonic stem cells show amazing potential to cure various disease such as cancerRead MoreStem Cel ls 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 MoreStem Cell Type Is Best?1264 Words   |  6 PagesTopic: Stem research, which stem cell type is best? 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 MoreEmbryonic Stem Cells615 Words   |  3 Pagesinto spinal cord injuries. One of the topics he pushed for was embryonic stem cell research. Christopher Reeve died on October 10th, 2004, never fulfilling his goal to walk again. But if he had gotten the support and funding for stem cell research, his story might have ended differently. Embryonic stem cell research should be funded in the U.S because it could lead to the treatment to many diseases, there are other sources of stem cells, but they are limited to their use, and the eight-celled blastocystsRead MoreThe Controversy Of Eugenics And Genetic Engineering1632 Words   |  7 Pagesproject ended in the successful mapping of the underestimated 20,500 genes that make up a human’s genome and â€Å"has given the world a resource of detailed information about the structure, organization and function of the complete set of human genes† (â€Å"An Overview†). In modern times, eugenics has evolved into genetic engineering, and it is still as controversial a topic as it was in the 1940s. But why is that so?

Scientists discover the capabilities of stem cells through their ability to repair, their opportunity of treatment, and their potential in future research. Stem cell research is the gateway to opportunities of treatments for diseases and possible cure for cancer, as scientists test the capabilities of stem cells.

This technology offers hope to millions who are victims of a multitude of diseases and disorders. It can be used to regrow limbs, create organs, attack genetic diseases, treat malfunctioning bladders, etc. However, this same technology is also one of the most controversial debates in science today. If you type â€Å"stem cells research† into your Google search bar, you will most likely find not only advances in this field or a basic overview of stem cells, but articles on
