In Brazil 2009, there was an 18 year old boy that had half of his jaw and teeth removed because of a tumor. Scientists took some of his bone marrow and extracted the adult stem cells from it and formed an osteoblast, which is a bone forming cell. Six months after the osteoblast was injected, it started forming new bone material which filled the gaps (NIH Stem Cells). Stem cells could be a genius way to treat many diseases and disorders and it should be supported by everyone.
Habitually, the majority of significant scientific discoveries that have occurred over the course of human history have been the center of fierce debate and controversy for one reason or another. From radical perspectives such as the Earth’s orbital around the sun to the theory that the planet isn’t geographically flat, scientists are often at the focal point of ethical debates. In regards to current advancements, nothing may be more controversial in modern day science and it’s general public than the research of embryonic stem cells. The utilization of stem cells in the process of injury and recovery is ethically justified because it involves informed consent by voluntary egg donors who aspire to contribute to research (when referring to embryonic stem cells), and may be the only effective and efficient method in central nervous system/spinal cord injuries that involve impaired cells that are not able to go through the cell cycle for mitosis. Technological advancements pertaining to stem cells and further research towards their significance in the medical field are morally correct and could be a critical method of prevention towards injuries and impairments that may cause permanent paralysis in everyday patients.
In preparation for this thesis on the topic of stem research and application; I gathered data through various methods to reach a broad consensus on the public impression of stem cell research. In this chapter I will discuss the findings of those ventures and the impressions it made on my research. I conducted a survey asking general information on the public’s knowledge of stem cell research and held a classroom forum asking for open opinions on research.
Thesis: Stem cell research is a great example for the controversial uprisings by advances in bio-medical research. 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. Moreover, I will point out how stem cell research is beneficial in today's society.
With exponential increases in the capabilities of modern technology, it only fits that we use this technology to further our existence as a species. Embryonic Stem Cell Research is one of the ways we have come up with to advance our species into the future. However, the perpetrators and supporters have been under fire and controversy since its inception in 1979. The protesters are fighting it mainly because it is destroying unborn fetuses in the process.Personally, I have a special and specific connection to embryonic stem cell research. As a Type 1 Diabetic, I know that the Juvenile Diabetes Research Foundation uses embryonic stem cell research in its efforts to find a cure for Type 1 Diabetes. The main use for the stem cells they have is
Stem Cell Research: Should we continue to allow scientists to create new embryonic stem cell lines?
After patients have gone through heart disease, like any other injury, therapeutic steps must be taken. Therapy and rehabilitation of damaged hearts has been improved through the utilization of stem cells. Therapy includes strengthening of the damaged area as to prevent the incident from reoccurring and getting the patient back to their normal life. Scientists, again, used rats that had had induced myocardial infarctions. This
Many controversial and moral stricken issues have been put into question in today's modern society. Some of which include gay marriage, and abortion. Yet one of the most controversial has to be stem cell research. A Stem Cell is a "generic" cell that can make exact copies of itself indefinitely. It also has the ability to make specialized cells for various tissues in the body such as the heart muscle, brain and liver. But why exactly is stem cell research so controversial? Well mostly those who oppose embryonic stem cell research do so on the grounds that the cells die in the process. But what those people might not know is that an embryo is no bigger than a pinhead. And therefore there is no human suffering. Stem cell
Additionally, embryonic stem cells have allowed drug testing to be made safer. It allows scientists to test the drugs on cells that are better representations of human cells than the previous test subjects, which were animals. Embryonic stem cells also allow scientists to study human development within the embryonic stage, and cellular reactions to disease. This means that because these cells are actual human cells, they will react to disease and disorders in the same fashion as the cells within human people. By looking at this reaction and development, researchers gain a clearer understanding of what these disorders are, how they affect human development, and possible treatments, cures, or preventative measures. Another point of progress for
A Stem Cell is a similar cell to a multicellular organism. That organism has the ability make an infinite amount of the same type cells.
1) How are stem cells different from normal cells? Why are these differences important for medical research?
Stem cells make up every organ and tissue that reside inside the human body. These cells help to regenerate and replace defective tissues and cells that are injured and destroyed within our body everyday. Former President, George W. Bush, felt so strongly opposed to the development of this research that he cast the first veto of his presidency when Congress tried to broaden the scope of the Stem Cell Research Enhancement Act of 2007. In this veto he stated that, “This bill crosses a moral line that I and others find troubling.” (1)
“The proliferative and developmental potential of human ES cells promises an essentially unlimited supply of specific cell types for basic research and for transplantation therapies for diseases ranging from heart disease to Parkinson's disease to leukemia” (Thomson &Yu, 2006). As stated by Junying Yu and James A. Thomson, it is true that embryonic stem cells are very adaptable and hold many mysteries in medical science, but why are they so heavily debated upon? Embryonic stem cells, or pluripotent cells, are cells derived from embryos that have the potential to become any bodily cell. Research of these cells allows us to understand human development and how disorders or illnesses form as people grow older. The main controversy that surrounds
Stem cells are cells that are found throughout the human body. They reproduce over a long period of time without changing. Stem cells can produce specialized cells, such as brain, muscle or lung cells. Stem cells in the last few years have recently made a big debut because medical professionals have discovered so many unique qualities to stem cells. They are on the cutting edge of medicine because of all their uses and the qualities that make them so unique from any other cell in the body. Stem cells have the power to make so many breakthroughs in the medical world. Medical researchers have all ready found so many ways that stem cells can be used for the better of so many people. Genes play an important role in determining what genetic traits or mutations we receive. Researching stem cells can help determine this. Stem cell research is useful for learning many things about human development and about how the body has the power to repair itself. Researchers are finding new ways each day that stem cells can be used and the possibilities that they find for stem cells could be endless. A few ways they can be used to treat diseases, be used as graphs for burn victims or surgical use, and even to correct birth defects. The pros of stem cells are limitless.
Many of us have all heard the saying that a “lizard can lose its tail,” and bizarrely enough it will grow back. This was always considered impossible for humans, an idea belonging in the realm of science fiction, but now the regeneration of tissue is an extremely realistic possibility. Despite some opinions, this process does not happen naturally, or take place as cinematically as one might imagine. Over the past decade, there have been major advances in regenerative medicine, commonly known as stem cell research. Stem cells are undifferentiated cells within the body that have the capability to specialize into any tissue. They are most commonly found in cord blood, bone marrow, organ donations, placenta, and embryos . Stem cells are seen by some as a new miracle treatment, encouraging many countries to invest in their research.
