Stem cells are a special form of human life: they are alive and contain human DNA. They have a unique feature in that they can be coaxed into developing into some or all of the 220 cell types found in the human body. Eventually, stem cells may be routinely used by doctors to generate new organs or new replacement body parts for people: They might become a new pancreas to cure a person with diabetes, or new nerve cells to cure a paralized person, etc.
To realize the promise of novel cell-based therapies for such pervasive and debilitating diseases, scientists must be able to manipulate stem cells so that they possess the necessary characteristics for successful differentiation, transplantation, and engraftment. The following is a list of steps in successful cell-based treatments that scientists will have to learn to control to bring such treatments to the clinic. To be useful for transplant purposes, stem cells must be reproducibly made to:

History of Stem Cell Research QUESTION: What is the history of stem cell research? ANSWER: The history of stem cell research had a benign, embryonic beginning in the.
Throughout your academic career, you will usually be asked to write an essay. You may work on an assigned essay for class, enter an essay contest or write essays for college admissions. This article will show you the writing and revision processes for all types of essays. Then, it will explore how to write narrative, persuasive and expository essays.
Stem cells are base cells, they are like cell blanks. As we age, these cells are no longer blank, but rather become things like eyes, tissue, white blood cells /etc. The research is the process in which they are obtained, and how best to use them. Stem cells could, in theory, resolve most of our diseases and genetic illnesses. The controversy is where we are currently getting them. Since these are new cells that have not been given a form, we can only harvest them from unborn fetuses. Whatever your views are on that, there are some studies now indicating a grown man could harvest them off his arm, or other existing cells. Hope that helps
Pro "The politics of abortion keep stem cell research in limbo." Daniel Perry, executive director, Alliance for Aging Research "Keep stem cell research publicly funded, carefully regulated." Arti K. Rai, assistant professor, University of Pennsylvania Law School "These studies are of great importance for biomedicine." Ihor Lemischka, associate professor, Department of Molecular Biology, Princeton University Con "Conduct studies in which no humans are killed to obtain stem cells, and no patients are harmed from receiving them." Micheline Mathews-Roth, MD, associate professor of medicine, Harvard Medical School "Human beings should not be … biological raw material." Douglas Johnson, legislative director, National Right to Life Committee "Instead, increase funding for adult stem cell research." David A. Prentice, founding member, Do No Harm: The Coalition of Americans for Research Ethics Argument against embryonic stem cell research: People who believe that personhood begins at conception generally oppose stem cell technologies, because these involve the destruction of human embryos. this is something i wrote a few years ago: it s not too much but you can address the questions i answer 1. What is a stem cell? What is an embryonic stem cell? A stem cell is a cell that can make copies of it’s self and the copies may become other types of cells. Scientists are trying to cultivate the stem cells to reproduce other specific parts of the body. An embryonic stem cell is from an “embryo generated by in vitro fertilization.” When an egg cell divides, a multi cellular blastocyst is formed. The inner cell mass of the blastocyst is consists of embryonic stem cells. Stem cells can be transferred into Petri dishes to be cultured with pipettes. Embryonic stem cells are very “pluripotent,” meaning the multiply easily and unlimited numbers could be produced. They can differentiate into cardiac cells, pancreatic cells, bone cells, and nerve cells. 2. How are stem cells different from other body cells? What properties make them uniquely useful? Stem cells can differentiate into different types of cells. 3. How can embryonic stem cells be used in medicine? (Give two specific examples). Embryonic stem cells can be used to treat diabetes, Parkinson’s disease, and spinal cord injury. Embryonic stem cells could differentiate into beta cells which would restore the ability to produce insulin, which help take in glucose from the bloodstream. 4. Why is the use of embryonic stem cells so controversial? It is controversial because although stem cells can treat several diseases, it requires an embryo or fetus, which would “give rise to” the illegal sale of the embryos or fetus by doctors. It also is involved with religious and social issues. 5. What is your opinion on the use of a) stem cells and b) embryonic stem cells. Explain your reasons. I think that if they could thousands of lives then why not use them, but only get the embryos from lives that are already lost, even if it means they will be more rare.

PubMed is freely available on the open Web http://www.ncbi.nlm.nih.gov/pubmed?term=stem%20cells The best thing to do would be to go to your local public library (college library if you re in college) and search through the databases offered there. Examples of databases to look for include: HealthSource: Nursing and Academic Edition (Ebsco) Medline (sometimes offered through Ebsco, sometimes another platform) ProQuest Nursing and Allied Health Source (there are several others which your library may or may not subscribe to) Many libraries today offer research assistance through some form of chat service.
