Essay On Pluripotent Cells

In October 2014, a study showed that stem cells could help people with macular degeneration, which is a disease that causes continuous loss of sight. Researchers followed eighteen patients for three years and saw no signals of rejection of the transplanted stem cells (Young). Stem cells can also be used to create brain tissue. The creation of brain tissue with stem cells will provide the treatments for Alzheimer’s, Parkinson’s disease, and Dementia. These treatments may not cure the disease completely, but it could stop the progression of the disease. It could also reverse some of the damage already done. “Anything that might reasonably be called a real brain is going to have to pass more tests than simply being made of brain cells and looking a bit like a brain under a microscope”(Coath 4). “Any technique that gives us ‘something like a brain’ that we can modify, work on, and watch as it develops has to be exciting”(Coath 4). On September 2013, the creation of cerebral organoids was achieved. Cerebral organoids are pea-sized brain tissue. This achievement of brain tissue organs can help researchers explore important questions about brain development and brain functions. All this research and new developments on stem cells gets researchers a little closer every time to actually finding the cure for a brain

The controversy due to embryonic stem cells is quite debatable. Both sides present many strong reasons that prove their point, but it is still, frankly, nearly impossible to take a stand from an unbiased view. "This is the first study showing that embryonic stem cells can be used for brain and spinal cord repair in an animal model of a human neurological disease," said researcher Oliver BrŸstle (a neuropathologist at the University of Bonn in Germany) referring to the study done on rats (CNN). Just like Oliver BrŸstle many scientists around the world agree that embryonic stem cell show much welcomed hope of cure of spinal and brain repair. In addition to healing spinal and brain injuries, the embryonic stem cells can also treat diabetes, a disease which 54%

Before we determine how stem cells can treat various diseases including spinal cord injuries, let us first

There are many different types of stem-cells which can be implanted in patients to regenerate or replace the damaged or abnormal cells caused by not only diseases like Parkinson's but also Alzheimer's and spinal cord injuries (2). A specific example in relation to Parkinson's is the harvesting of embryonic stem cells. These human embryonic stem cells can be transplanted into the brain to replace and create dopamine neurons. The controversy is in how one can obtain these stem cells. During fertilization, in humans, the embryo is hollow and contains cells that eventually develop into a fetus (1). Researchers have discovered, as recently as 1998, that the cells in the embryo contain all

“I truly believe that stem cell research is going to allow our children to look at Alzheimer’s and diabetes and other major diseases the way we look at polio today, which is a preventable disease” (Solomon). Susan Solomon has founded the New York Stem Cell Foundation and has been seen as the hero for stem cell scientists around the world. Over the past couple years, stem cell research has been at its high; scientists all over the world are using these cells to try to find new ways to cure life threatening diseases. Some have used stem cells to treat patients who have been brain dead recently and these cells made the dead portion of the brain start functioning again. Also, some scientists and doctors have

Embryonic stem cells could cure many things such as Alzheimer 's disease, Parkinson 's disease, Diabetes, and many other things (Stem Cell Information). This category could broaden but how will that ever be known

For many people, Alzheimer’s disease, Parkinson’s disease, and other neurological issues are a difficult obstacle. However, imagine a world where these problems could be solved. Scientists believe that one day, that could be our world. With the use of stem cells, it would be possible to replace cells that have been killed by disease. Stem cell research has been around for about 30 years, but hasn’t been widely practiced due to the many people who have major ethical problems with it and the ban in which removed federal funding for embryonic stem cell research. Since a large majority of stem cell research involves the use embryos, a lot people

Embryonic stem cell research is already proving useful in the study of regenerative medicine, human development, cellular responses to disease, drug testing, and many other fields. This is just the tip of the iceberg. There is still much more to be discovered and created using the research platform this stem cell research provides. Although opponents argue it to be unnecessary, it is clearly important because embryonic stem cells are the most pluripotent stem cells, and all stem cells are required for the full potential of research. Embryonic stem cell research can also be justified, because the embryos come from sources where they would otherwise be destroyed, but they are instead contributing to the advancement of medicine and science. Finally, and notably, this field is supported, and is clearly leading to a new future of science and research. This research is important to everybody because it is creating and will continue to create cures, medicines, and therapies. Any person could be struck by a disease or ailment unexpectedly, and the more research scientists are able to do with a variety of options means that person may not have to experience discomfort or pain for long. This research is helping reduce or eliminate fatal disorders as well, meaning that it could possibly save a loved one’s life, if they struggle with a terminal illness. In these ways, embryonic stem cell research continues to be an issue that affects, and should be understood by, everybody. Embryonic stem cell research, though controversial, is a field so valuable and with so much potential that it is important to contribute

From the medical perspective, stem cell research is viewed as very promising due to the fact that if stem cells can be introduced into patients with a range of illnesses, they could possible help regenerate the tissues and organs of the patients and thereby help heal illnesses (and especially degenerative illnesses) that are currently incurable. For example, Lovell-Badge has indicated that diabetes, Parkinson's disease, and Huntington's disease are among the illnesses that could

Will embryonic stem cells prove to be equally disappointing as many hoped for cures in modern history? No one knows. However, a tragic occurrence following one particular fetal tissue transplant for Parkinson's disease, when such was thought to be a cure, should give us pause. Some of the tissue placed in this man's brain may have been from an earlier gestational age than is customary in American clinical trials - that is, it may have been more embryonic than fetal in nature. Within two years after the transplant this man died mysteriously - and an autopsy revealed that masses of "nonneural tissue" such as skin and hair had filled the ventricles of his brain and cut off his breathing. Researchers theorized that this tissue may have

A stroke materializes when oxygen is unexpectedly cut off from the brain occasioning in brain cells dying. There are two chief kinds of strokes. One is when blood clot befalls and blocks the bloodstream decreasing oxygen flow to the brain i.e. this is called as "ischemic stroke". The other one is the "hemorrhagic stroke"

Scientists and researchers believe that Human Embryonic Stem Cells hold potential cures for numerous diseases in today's society, including multiple sclerosis, Parkinson's disease, Alzheimer's disease, diabetes, Lou Gehrig's disease, Hodgkin's disease, hundreds of immune system and genetic disorders, spinal cord injuries, heart disease and just about every type of cancer. In today's world there's over a million Americans who suffer from deadly diseases, not only adults but innocent children that deserve to live a healthy life. These deadly diseases can be cured or treated in a more effective way than they are treated now with the help of the human embryonic stem cells. According to the Poll on "American views on stem cell research in the wake of the death of Ronald Reagan" which was prepared for results of America, shows that a sum of 73% highly supports and somewhat support this controversial process (Results of America, 2004). Even though this topic has brought continuous political attacks and very limited funding, Human Embryonic Stem cell research has made considerable contribution to the battle against disabilities and incurable diseases. A great example of success by using human embryonic stem cells was made by Dr. Hans Keirstead in the Roman Laboratory at UC Irvine; he restored myelin insulation around damaged nerves, returning motion to partially paralyzed rats. (Journal of Neuroscience, 2005) .

Despite the stigma surrounding embryonic stem cell research, there are many positives that outweigh the negatives in medical and scientific settings. Due to the knowledge of this, continued funding and support is critical for the advancement of these therapies and science as a whole. Diseases that can be aided by unabating financial and moral support are but not limited to, spinal cord injury, heart disease, parkinson 's disease, alzheimer 's and Lou Gehrig 's disease, more commonly known as ALS. Funding via the government was passed into law in 2008 by President Barack Obama. As the election comes upon us it is important to keep in mind that the continued federal funding for embryonic is at stake.

Parkinson’s disease, Lou Gehrig’s disease, Sickle Cell Anemia, Alzheimer’s. This world is plague by countless diseases and there existed a time where, after many failed research attempts, scientists began to believe that people would always suffer from these diseases. However, with the introduction of stem cell research those past notions were dismissed. Upon their introduction, stem cell’s provided a new hope to the world and it proved itself to be an invaluable asset. Through stem cell research, a multitude of cures have been brought upon the world and these diseases that were uncontrollable in the past, can now be regulated and the ones suffering from now have a chance at living a better life. Sadly, there are many people who

Another potential utility of iPS cells is the modelling of human diseases. The idea to study genetic disease mechanisms (e.g. Parkinson´s disease, Alzheimer´s disease, amyotrophic lateral sclerosis) is based on the generation of disease-specific induced pluripotent stem cell lines from patient´s somatic cells. These cells should have a phenotype and properties of that particular disorder enabling us to broaden our knowledge about phenotype, genetics and progression of the disease. (Colman A. and Dreesen O., 2009) Induced pluripotent stem cell-based disease models act as an innovative tool that can be also widely used in therapeutics development and testing of new compounds. This would lead to minimizing of the use of animal models in preclinical testing and thus decreasing the cost for drug development. Further, effective development of therapeutics can be achieved by establishing predictive toxicity essays using differentiated disease-specific iPS cell lines (Inoue H. and Yamanaka S., 2011). Induced pluripotent stem cells can be also applied in the cell replacement therapies and studies. These iPS cells should be well characterized prior the transplantation. The main challenges we need to overcome are tumor formation and lack of cell type differentiation. Moreover, iPS cells generated by the traditional viral vector method cannot be used for cell replacement therapy. In conclusion, other potential
