Cellmates In 2013 about 580,350 Americans were projected to die of cancer, almost 1,600 people a day. Cancer remains the second most common cause of death in the US, accounting for nearly 1 of every 4 deaths (Cancer Facts). Doctors and scientists are always trying to discover new ways to help battle cancer as well as other diseases. Doctors have tried everything from plants to radiation to try and destroy cancerous cells. Instead of destroying them Scientists and doctors are now trying to replace the old cancerous cells. In order to replace these cells they will need new cells. Stem cell research is the newest way doctors are trying to help with diseases. There are different types of stem cells. Stem cells are cells found primarily in embryos, and they have not yet taken on the characteristics of any particular type of cell, such as bone, muscle tissue or brain matter. The newest research being done is with embryotic stem cells. Embryotic Stem cells have been used in medical therapies to aid patients with many types of diseases; that being said it is imperative that we continue researching, practicing, and funding these medical advancements. Pro-life supporters often claim that the use of adult stem cells from sources such as umbilical cord blood has consistently produced more promising results than the use of embryonic stem cells (Stem Cell Controversy). Adult stem cells can also be used in place of embryotic stem cells. Scientist have discovered new ways to make the adult stem cells adapt like the embryotic stem cells. In Japan scientists use a method called stimulus-triggered acquisition of pluripotency” or STAP to transform adult cells into a embryotic like state. Using this method scientists are able to take an adult cell ... ... middle of paper ... ...g stem cells destroys potential life, the benefit to the greater good greatly outweighs the destruction of potential life. In a perfect world with an unlimited amount of stem cells all diseases and illnesses could be cured. Those working in the medical world can greatly improve the quality of human life using stem cells. With stem cells, people will live longer, healthier, lives. Many diseases would be completely eliminated. However, only when scientists and doctors fully understand how to implement the embryonic stem cell, can all this happen. When the doctors and scientists have all of the lines they need, then they can cease destroying embryos to obtain the stem cells they require (More Ethical Stem Cells). The biological world and the field of stem cells specifically, require the support of the federal government as well as the people to make all this possible.
Late one night a woman is driving home on the freeway, she’s hit head on by a drunk driver and killed. The man is charged with two accounts of murder; the woman, and her four-week-old embryo inside her. By law, everyone human being is guaranteed rights of life; born or unborn they are equal. 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 cancer, congestive heart failure, Alzheimer’s and Parkinson’s disease, muscular dystrophies, and more. The methods by which they are obtained is controversial. Research on embryonic stem cells is unethical, unnecessary, and purely homicide.
Over the past decade scientist and the U.S government have been debating about funds for stem cell research (SCR), the amount spent depends on who is in office. The Democratic Party fully supports SCR, but the Republican Party somewhat opposes the concept of SCR, arfuing it violates the Christian principle of life. As a result, this topic is considered controversial, but also beneficial if allowed. Despite the controversy, SCR should be well funded for medicinal use, because blank stem cells (SC) can be used to regenerate bones and muscle tissue, they can be used to control or even reverse neurodegenerative disease, and because they can be used for therapeutic cloning.
Stem cell therapy is a controversial topic that falls on the list of things not to discuss over thanksgiving dinner, very much like religion and politics. While the potential of stem cell research and therapy stand to make leaps of progression in cures for disease like Cancer and Alzheimer’s; Pros, Cons and morality still surround the issue.
Because stem cells are essentially a blank slate, scientists are theoretically capable of growing any human tissue cell. There is enormous medical potential in this. Stem cell research is the next step in advancing the medical field. It is comparable to the discovery of penicillin or the inoculation for smallpox.
Stem cells have been under intense research because of their remarkable potential to develop into many different cell types within the body. Under certain experimental conditions, they can be induced to become tissue specific cells with special functions. When the human stem cell was first discovered, researchers primarily utilized embryonic stem cells (ESCs), undifferentiated cells derived from a 5-day preimplantation embryo known to develop into cells and tissues of the three primary germ layers (Rippon and Bishop 2004). Because the extractions of human ESCs result in the destruction of an embryo, stem cell research has been highly controversial. However, recent advances have allowed the creation of induced pluripotent stem cells (iPSCs), somatic (adult) cells that have been “reprogrammed” into a pluripotent state. (Takahashi et al. 2007). In this paper, I propose that human induced pluripotent stem cells be more strongly considered as a model for studying human development. Strengths and weaknesses of using the hiPSCs as a model, as well as the methods of inducing pluripotency will be discussed and reviewed.
The ethical issues behind the method in which stem cells are obtained out weigh the benefits of stem cell therapy. We should not try to play God, in the aspect of creation of living beings just to be sacrificed for the “betterment of mankind”. Many egregious acts have been committed under the guise of “the greater good”. This is one instance in which the ends do not justify the means.
Stem Cells are cells that scientist have began to try and use to help people. “In the mid 1800s it was discovered that cells were basically the building blocks of life and that some cells had the ability to produce other cells.” With the discovery of stem cells came the opening to a new area of development in what could be done with health and medicine of the world. Of course throughout history, stem cells have been a very heated subject between different groups of people who believe it is right or wrong. Some people believe that this form of research is against ethical or moral values. They too see this as being wrong because they view human embryos as a form of life. These cells are neutral cells that can be turned into any other one that is needed at the time. Stem cells can make more of themselves when they aren’t being used allowing them to be ready when something happens. In the human body, stem cells help repair the tissue that has been broken, torn, or lost. They help fix bones, heal abrasions, and even repair internal organs if needed. Scientist have the ability now to mani...
What if there was a cure for cancer or a treatment for spinal injuries? Would you support the research? What if there was a way that you could repair damaged nerves. Some believe that stem cells may hold the answers to some of these questions. What are stem cells and why should you or I even care about them? Some believe that they are a miracle treatment waiting to happen while others believe that stem cells are highly immoral. Why does so much controversy surround the issue? Why is the conversation of stem cells feared by some and praised by others? To some stem cells are the medical hopes for the future, something for us to hang on to as we do battle with major diseases that include cancer, Parkston’s disease and spinal injuries. To others stem cell researchers are murderers who are trying to play God’s hand. A many have pledged their support to stem cell research including a few well known celebrities. Reeves’, who was best known for his role in the early Superman movies, and J. Fox two well-known celebrities, have pledged to stem cell research, both have created a private fund for the research of stem cells. This celebrity however has not swayed everyone to support stem cell researches cause. Just as there are supporters of stem cells there are those who believe that the use of stem cells is immoral. Since the first stem cells were separated there have been doctors, religious groups and even some political figure head have shown their opposition for stem cell research. Even with the knowledge and promise that stem cells show many of those who truly oppose stem cells have not changed their mind. The question is are their reasons good enough to halt the research of stem cell or are they just holding back what will soon be inevi...
From the discussion above it is very clear that there are different opinions on the pros and cons of stem cell research. Based on the recent researches, scientists have the capability to work out the alternatives for embryonic stem cell research. And the usefulness compare to embryonic stem cell remains unknown. Undeniably, the stem cell research issue has its most complex parts to be resolved and surmounted. But perhaps we can disclose the way to carry out stem cell research with the balance of bioethics and most importantly, do no harm for humankind one day.
Stem cell research is the study of growth, use, and termination of human embryos. There are two main types of stem cells; the most common is embryotic cells and the other is an adult stem cell. The need and popularity of stem cell research is growing due to the advancements of technology and the growth and influx of sickness and disease. Stem cells are looked upon as an almost miracle treatment and have the potential to grow into a whole new type of cell research.
One problem that I think is an issue in the stem cell debate is the destruction of the stem cells and how it’s practically the same thing as destroying a human being. I don’t believe that researchers and scientists should continue using embryonic stem cells for research because we are obviously not finding a cure for human diseases yet although for animals we are, it’s just not right to destroy a human being if we cannot find treatments for major diseases within a decade or so.
You’ve probably heard of stem cells as the genetically modified cells, which makes us humans capable of manipulating our genetic information to get optimal results. It would be amazing to change how our genetics build us, right? Maybe, depending on your opinion, but the hidden truth about stem cell research is it is not as good as some claim it to be. There are a lot of possible consequences when dealing with stem cell research, especially when the technology is advanced but still in the research phase.
tem cell therapy is a type of cell therapy wherein cells are introduced into the damaged tissue so as to treat the disorder or the injury. There are a number of medical researchers who believes that the stem cell therapy has the potential to change the treatment of human diseases and reduce the suffering people face when they have a disease. They believe that there are a lot of potential to replace the damaged and diseased tissues in the body without getting the risk of rejections.
The scientific world is buzzing with excitement now that researchers have shown that stem cell therapy improves lung function in mice. Headlines scream that new treatment options may soon be available for COPD patients, yet people have already had stem cell therapy performed successfully. Although news articles promise a bright future for people with lung diseases, none of the articles mention that individuals can choose stem cell therapy in the United States today, if they are eligible. This is a disservice to individuals with chronic lung diseases who have a right to know all of their options.
As modern medicine advances humankind is making incredible discoveries in cell regeneration. Studies of regenerative medicine have been encouraged to work towards replacing degenerate human cells to restore full functionality to the tissue or organ concerned, however these practices are unethical and immoral as they go against the very basis of life. Regenerative medicine involves harvesting stem cells, then differentiating them in order to create specialised cells. Stem cells are defined as undifferentiated cells with the ability to give rise to more cells of the same type and form specific cells through differentiation, and so are harvested from bone marrow, umbilical cord blood, peripheral blood and embryos.
