Research in the development of stem cells has become increasingly popular over the past decade. The fascination in the study of stem cells by scientists comes from the mystery of what the essential properties are and how cells differ. With the discovery of determining how stem cells are self renewing and identifying what causes stem cells to become specialized leads to the ability to create more cell-based remedies as well as preventing birth defects, more precise screening for new drugs and cloning of organs and tissues. Stem cells are unspecialized cells that renew themselves for long periods through cell division. They can also become specialized functional cells such as beating cells for heart muscles and insulin-producing cells for the pancreas or nerve cells. However, this development is controversial being that there are benefits and downfall in which humans are being to an extent “genetically engineered.” Although there are pros and cons of using stem cells, the numerous beneficial possibilities indicate that we should perform the experiments to better our society under extensive scrutiny by the government and public.
Embryonic stem cells and adult stem cells are the two primary types that scientists work with. Stem cells are unique because they are unspecialized to any tissue-specific structures but can develop specialized cells and in culture develop indefinitely. They replicate themselves over and over again causing large growths of cells over a period of time called proliferation, yielding many other unspecialized stem cells. However if the parent stem cells give rise to specialized stem cells the process is called differentiation. Scientist are only at the tip of the ic...

...future for improving human diseases and disorders. If put into the wrong hands stem cell technology could be very detrimental to society however with the help of governmental controls and laws I do not believe there would be many problems. Although the PCB and NBAC have not been able to come up with a clear line of where to begin and end stem cell research and experiments they are improving their communication skills with the public about the ethical issues that will arise from stem cell research and are working on the awareness of the issue and sovereignty of the consequences.

- Stem cell research. Simple words that to some mean a lot more than a new potential scientific field. It is simply the creation or repair of another life form from an earlier form. Stem cells have the chance to change all that we know in the medical field as well as the potential to heal old wounds and heal damaged organs. This point causes much debate and anger of those opposed to stem cell research but they ultimately look at the process and not the form or result of it. Stem cell research has incredible potential.... [tags: Stem Cell Biology, argument]

- Stem cell research has been met with major ethical concerns in the media and as a result the research has tried to address the concerns of funding and ethical dilemmas. There are 6 major concerns raised in the review, such as: Tumor Formation, Contaminating Animal Products, Genetic Compatibility, Funding Issues, Selecting and generating the Right cell type from transplantation and new approaches to generating embryonic stem cells (ES). In the use of stem cells, there is room for error, especially in transplanting cells to renew or help cells.... [tags: transplanting, research, disease, stem cell]

- An interesting aspect of stem cell research is how politically charged it was from its very beginning. Originally born into a conservative playing field, the bounds on stem cell research were never as open as they are now, having been suppressed by political opinion for several decades. Numerous accounts of voting to support stem cell research were blocked by individual opinions of people with the influence to do so. Today, stem cell research is more open and accepted, due to technological advancements, but I think more importantly, a changing political mood.... [tags: Stem Cell Research Paper]

- As the research teams of the EuroStemCell project teach in their educational short film A Stem Cell Story, there are certain stages of development while in the uterus where most of our cells stop dividing and stabilize into a specific kind of cell. They do not mutate throughout our life. These cells are referred to as specialized cells. Once they are damaged or die they cannot regenerate themselves. There is one kind of cell that never specializes during development. They are called stem cells and they are the only known cells that can renew themselves....

- "Stem cell research is the key to developing cures for degenerative conditions like Parkinson's and motor neuron disease from which I and many others suffer." -- Stephen Hawking As college students, it is important that we know and care about the issue of stem cell research. Stem cell research is currently legal in most countries. The United States, normally a leader in new frontiers, is one of the last to explore this territory. As it is slowly being pushed forward, we are going to have to know about it.... [tags: stem cell argumentative persuasive argument]

- In England, during the late 1790s, physician Edward Jenner discovered how to vaccinate people against smallpox. Approximately 190 years later, in 1980, smallpox was declared eradicated (Edward Jenner). Today, humanity continues to follow in Jenner’s footsteps through working to cure and eradicate diseases that threaten people across the globe. Unfortunately, however, vaccines and antibiotics do not always work, and scientists need to find new ways in which to cure the diseases that have yet to be cured, such as Alzheimer’s disease, Parkinson’s disease, and diabetes....

- Introduction Stem cell technology is developing rapidly to bring tissue and organ regeneration from the foreground of current research to the hands of physicians for therapeutic interventions of injuries. Though this field is rapidly progressing, several limiting factors have reduced the efficacy and survival of many transplanted cells. To understand the limitations, a deeper understanding of the chemo–mechanical environment of an injury is needed. Tissue and organ development from specific progenitor cells is tightly controlled by the surrounding biochemical environment.... [tags: science, medicine, stem cell research]

- The Controversy Over Stem Cell Research In a lab at the University of California, a scientist carefully isolates several cells and locates them to a petry dish. A few days later, he returns to find the cells pulsating like a human heart (Gorman 58). This account has actually been occurring at several scientific labs across the nation. These cells, known as stem cells, produce nearly all the other cells and tissues found in the human body (Sobel Sep 4, 22). Intensive research has found that when these stem cells are grafted with human tissue, new tissue is formed and the diseases found in that tissue are cured....

- Stem Cell Research This research paper will focus on stem cell research and the ethical issues that are attributed to this subject. This topic will be narrowed down to Embryonic Stem Cell research in that there is a great debate going on how to conduct this research ethically. The importance of embryo stem cell research is that the research could help save lives and also the debate is that it is morally wrong to kill an embryo due to the fact it still a living organism. The issue with embryo stem cell research is that an embryo is a living being and should not be used for research, because then the embryo would not be allowed to develop into the living form it is meant to be....

- Stem cells are cells that can form into any type of cell, they are found in bone marrow, embryos, fetuses, and blood from the umbilical cord. Early in development, a human embryo is made up of a hollow ball of cells called a “blastocyst”. Blastocyst cells divide and eventually develop into all of the tissues and organs of a human being, a process called “differentiation”. Embryonic stem cells can be grown in the laboratory from blastocysts and made to differentiate into nerve, liver, muscle, blood, and other cells.... [tags: Controversy, Debate, Politics]
