Stem Cells And Its Effects On Society - 909 Words
Stem cells are unspecialized cell that can both reproduce itself indefinitely and, under proper conditions, differentiate into specialized cells of one or more types. (Reece, Jane B., and Lisa A. Urry, 2011.) The term ââ¬Å"stem cellsâ⬠were first seen in scientific literature in 1868, a German biologist Ernst Haeckel used this term to describe the fertilized egg that becomes an organism. On February 2, 1963 the firs piece of evidence of blood stem cells seem, Ernest McCulloch and James Till conducted experiments on the bone marrow of mine and observed that different blood cells come from a special class of cells. In 1981, pluripotent stem cells are obtained from embryos of mice and are the first embryonic stem cells ever to be isolated. In 1989, Mario Capecchi, Martin Evans, and Oliver Smithies created mice which are missing specific genes. They created the mice using embryonic stem cells and homologous recombination. In 2007, they were recognized by the Nobel Assembly because their experiment proved to be an irreplaceable piece of evidence to understand how various human disease such as diabetes and cancer develop. On November 6, 1998 the first batch of embryonic stem cells that originated from early embryos. Then eleven years later, President Obama signed an executive order to repeal some restrictions on human embryonic stem cells research funds. On July 4, 2009, the National Institutes of Health had to create new guidelines on federal funding for stem research.

It is a single cell that can give rise to progeny that differentiate into any of the specialized cells of embryonic or adult tissues.â⬠This is a very simple explanation of stem cells by Dr. Stewart Sell, a cancer researcher. Stem cells are more or less blank cells. They are identical cells that can adapt to specialized cell types. There are two types of stem cells according to the U.S. Department of HealthRead MoreThe Debate Over Embryonic Stem Cell Research852 Words à |à 4 Pagesknowledge of stem cell research has already created the ability for doctors to print a functional organ just as easily as people can print a persuasive research essay. With great medical advancements comes great controversy. The main way researchers have been studying stem cells is by harvesting undifferentiated embryonic stem cells. Those who oppose embryonic stem cell research claim that stem cell harvesting d amages and kills the un-born embryo; however, because of advancements in the stem cell harvestingRead MoreStem Cell Research Should Be Continued For Many Reasons1303 Words à |à 6 PagesStem cell research should be continued for many reasons. Stem cell research can help save tissues, organs, and brain cells, it also helps to cure diseases. Looking at the big picture, stem cells could one day save our lives. Stem Cells are multi- cellular putty from which all tissues of the body are made.they have three general properties,. Those being that they are capable of dividing and renewing themselves for long periods of time, they are unspecialized, and they give a rise to unspecializedRead MoreThroughout centuries, scientists have discovered new and improved ways of curing certain types of1500 Words à |à 6 PagesThroughout centuries, scientists have discovered new and improved ways of curing certain types of diseases with medical treatments that continue to be discovered. When newly discovered, many treatments and cures are controversial. Immediately, society questions whether or not these medical practices are reliable, safe, and ethical procedures. Such as electroconvulsive therapy (ECT), also known as ââ¬Å"electroshockâ⬠, a medical procedure where patients who may be victims of schizophrenia or depressionRead MoreThe Medical Promise Of Embryonic Stem Cells1626 Words à |à 7 Page sEmbryonic Stem Cells Why should people suffer from diabetes, Alzheimerââ¬â¢s, sickle cell anemia, leukemia, and plenty of other degenerative diseases while the cure lies in our hands? After James Thompson, a developmental biologist, reported that he had derived the first human embryonic stem cell line (Thomson), the potential of curing degenerative diseases was revealed. Ph.D. holder and deputy director of FDAââ¬â¢s office of Cellular, Tissue and Gene Therapies, Stephanie Simek, explains that stem cells are unspecializedRead MoreA Research Study On Stem Cell Research1665 Words à |à 7 Pages Stem cells have advanced the way researchers look at curing what were once considered untreatable diseases. Modern technology has played a key role in the discovering of these stem cells and how they are used in the body. Many argue that the use of adult and embryonic cells is unethical and inhumane to society, however, there is one point taken into consideration when making that statement; if researchers could develop a cure for a disease that was affecting a family member of those who oppose itRead More A Look at Stem Cell Research Essay1424 Words à |à 6 PagesA Look at Stem Cell Research 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 preciseRead MoreStem Research On Stem Cell Research1747 Words à |à 7 PagesKelly English 111-36 25 November 2014 Stem Cell Research Stem cell research has cultivated a new, miraculous study in the health field. The study has led to an increase in curing diseases over the past couple of decades. Before stem cell research, diseases were destroying and devastating lives continuously on end. With the use of stem cells in modern time, diseases are no longer taking control of lives. The innovation in biomedical technology, such as stem cell research, has greatly impacted the understandingRead MoreHematopoietic Stem Cells to Cure Leukemia980 Words à |à 4 Pages Hematopoietic Stem Cells to Cure Leukemia Genetic Engineering consists in altering the DNA of a cell with the purpose of researching, as well as correcting genetic defects. (learn.genetics.edu) One of the human bodys cells has the ability to grow into any one of the bodys more than 200 cell types and this is called Stem Cells. They are not specialized and unlike mature cells, they can renew themselves and create new cells. Stem cells have a great potential, but extremely limited is the
