Human Embryonic Stem Cells originate from a preimplantation phase embryonic cell. These cells have the unique ability to differentiate into any type of cell. These cells are able to divide quickly, like they would during the process of fetal development. These qualities have made it possible for researchers to understand when and how certain cells differentiate, or change, to develop into different types of cells. Because of this, the researchers have been able to pinpoint the locations of certain genes and their gene switches, and are able to replicate this process in order to develop new tissue. These human embryonic stem cells are generated by a process of transferring cells from an embryo into a nutrient filled culture disc. On this disc the cells grow and divide. Once cells span the whole disc some of the cells are replated into fresh nutrient discs so that they will continue to divide and multiply. This process is completed and repeated several times so that there will be several millions of cells for the researcher to work with. The cells which are produced much undergo certain testing in o...

...also been cases of induced pluripotent cell therapy causing malignant tumor formation. Much more research and testing is essential before this can become an effective method of treatment and disease research. Different viruses are being tested for the transportation of the factors, and different types of cells are being tested for their likelihood of being converted back into stem cells.
Because of the controversy that using human embryonic stem cells has caused over the definition of life itself and how it is being used or abused by research scientists, it is easy to see how people can get swept away in looking toward something like induced pluripotent cells to replace embryonic research completely within the stem cell realm.

- Induced Pluripotent Stem Cells Stem cell research debates have echoed from class to class, and to hear that someone actually has a solution to this paradox, which can really compromise two very stubborn points of views, I could not but write my report about what I thought of a very “enlightening” article: 1. Objective analysis. Maureen L Condic’s “Getting stem cells rights” serves to emphasize the ethical part of stem cells research as it tries to ground the whole debate and market a new prospect of an embryonic stem cell called the induced pluripotent stem c...

- Induced pluripotent stem cells (iPSCs) have the capacity to have a widespread impact on biomedical research and therapeutic approaches to an array of diseases and disorders. These stem cells are of extreme potency because they can self-renew in culture while maintaining the capability to become virtually any cell type (Zhu and Huangfu, 2013). While there are many ethical concerns regarding embryonic stem cells, induced pluripotent stem cells arise from adult somatic cells that can be reprogrammed to enter the pluripotent state and have similar characteristics of embryonic stem cells such as having normal karyotypes, expression of telomerase activity, cell surface markers and genes, as well a...

- ... Although the National Institute of Health states that “it is not known if iPSCs and embryonic stem cells differ in clinically significant ways”, iPSCs are already being used to achieve the same results as ESCs in some applications without the use of embryos, removing the ethical concern associated with ESCs (National Institutes of Health, 2009). ESCs are capable of differentiating into all cell types, and can be used as a source of differentiated cells. In the report by Itskovitz-Eldor et al., they discuss the induced differentiation of ESCs in suspension into embryoid bodies, including the three embryonic germ layers....

- The path of embryonic stem cell research The great debate about embryonic stem cell research maybe over. What is the debate of embryonic stem cell. The debate is whether or not it is ethically or morally right to kill an embryo for a life, to save a life. The research behind the embryonic stem cell(hES cell) is promising though, and we may have found an alternative way of obtaining it because we can sidestep the issue of morality by using induced pluripotent stem cell for research rather than embryonic stem cells....

- Dr. Dan Kaufman, Ph. D. an associate professor University of Minnesota Stem Cell Institute, has said that, “human embryonic stem-cell research is not only ethical, it is an essential field to pursue to make key advances in biomedical research to treat diseases effectively where there are currently no cures… (thesurvivaldoctor.com).” I believe that stem cell research needs to receive government funding and research should expand in order to completely understand what diseases can be cured through stem cells, and if the benefits outweigh the risks involved....

- Introduction Stem cells are a certain type of cells that are classified by their ability to differentiate into different tissues. They are also self- renewing cells. There are three different types of stem cells that have been discovered (Iwamori, Iwamori, & Matzuk M., 2012). The types are embryonic, adult, and induced pluripotent stem cells. Research is currently being done to analyze the potential medical benefits of stem cells. There are also many different ethical questions surrounding stem cells (Shahid & Irshad, 2012)....

- Embryonic stem cells are being researched worldwide in an attempt to provide treatment for some degenerative diseases and human injuries. Although research is still being undertaken, these stem cells are providing a positive outlook on potential treatments however; as a potential human life is involved, is the use of embryonic stem cells to treat human diseases justified. Embryonic stem cells are obtained from the human embryo, which is developed from a fertilised egg (NIH, 2010). These embryonic stem cells are known as being pluripotent; the ability to develop into virtually any cell within the human body (Science Daily, 2014).... [tags: Stem cell, Embryonic stem cell]

- Stem Cell Research "The human being is single, unique, and unrepeatable, someone thought of and chosen from eternity, someone called and identified by name." This was the belief of Pope John Paul II (May). Stem cell research has shown promise and success for curing disease; however embryonic stem cell research must be banned because it requires the killing of embryos, there are alternatives, and embryonic stem cell research has had no successes. Shows promise and success Adult stem cells can be found in umbilical cords, placentas, and amniotic fluid.... [tags: degenerative diseases, embryonic cells]

- Cultured cell from animal tissue can be used to replace dysfunctional and dead tissues and organs. In our daily lives, our cells are damaged and some of the damaged cells are repaired, but others are destroyed. The destroyed cells are forced into dysfunctional state where it can no longer be divide and undergo apoptosis (Sens Research Foundation, 2014). Some of the lost cells can be replaced by tissue-specific stem cell but due to aging process, the stem cell becomes less effective, losing cells progressively and they are increasingly become malfunctioning....

- The article selected for this assignment is “Targeted Gene Correction of α1-antitrypsin Deficiency in Induced Pluripotent Stem Cells”, by Kosuke Yusa, et al., and was published as a Nature Letter on October 20th, 2011.1 This is a proof-of-principle study for a new technology developed by the authors for eventual application in cell replacement therapy. The authors used a novel combination of zinc finger nuclease and piggy-Bac methodology in human induced-pluripotent stem cells (iPSCs) to correct a single point mutation in the α1-antitrypsin gene that is known to be responsible for α1-antitrypsin deficiency in humans....
