Stem Cell Controversy Essay

1055 words - 4 pages

Stem Cell-Undifferentiated, primitive cells in bone marrow with ability to multiply and differentiate into specific blood cells.Many people ask the question "What is a stem cell and how can they be used in the medical field?" Researchers say that stem cells have become very important in figuring out the many questions of life, and may be able to help us in the near future (Edwards 54). Using these stem cells may help in finding cures to many diseases, yet on the other hand there still could be a possibility of a defect. Although there are a variety of advantages that come with using stem cells in the medical field, there are many effects that tag along with this process that many don't agree. Some call stem cells "magic seeds" for their ability to replicate and can develop into any into any kind of tissue needed. The embryonic stem cells come from the inner cell masses of donated human blastocysts. A blastocyst is a hollow ball of about 140 cells that develops several days after fertilization. Stem cells are capable of changing into any of 220 cell types that make up the human body, which is definitely helpful in many ways. Human embryos, only days old, must be destroyed to get these stem cells. This is what causes this "Stem Cell Controversy" because many people believe that the idea of destroying a human embryo is not morally right, while others do not mind at all. There are only four ways that stem cells can be obtained, such as from aborted fetuses donated by women at abortion clinics. There is also the process of fertility clinics. During the in-vitro process, clinics routinely fuse more than one egg with sperm. If planting a fertilized egg does not work the first time, then they can try again. Edwards 2 Also stem cells can be obtained by cloning human embryos. This way the mother can keep her baby and the doctors can use the embryos for testing. And lastly, scientists can get stem cells by making them such as mixing egg and sperm cells to create embryos, or in other words a test tube baby. The embryos from where the blastocysts developed were made in a laboratory dish, prepared to help couples having...

The Controversy over Embryonic Stem Cell Research

1161 words - 5 pages There is an ever growing controversy surrounding stem cell research. First off, stem cells, are the earliest of cells (basically the first cells that are created to form the human body) that give rise to other types of cells, and have the potential to turn into many different types of tissue. They are similar to cells called Totipotent cells, which are considered the master cells of the body, because they contain genetic information needed to

The Controversy of Stem Cell Research

1484 words - 6 pages The Controversy of Stem Cell Research One of the most controversial topics these days is Stem Cell Research. There seems to be a split opinion among societies about the research and whether it is socially and morally acceptable. As a society, we need to open our minds to the possibility of broadening our scientific horizons with stem cell research, and take the time to learn and understand whatever we can about it. There are a

The Embryonic Stem Cell Research Controversy

1006 words - 4 pages When James Thomson at the University of Wisconsin and John Gearhardt at John Hopkins University were able to culture human embryonic stem cells in a lab in 1998, they opened up an entire world of controversy now known as the stem cell debate. The importance of embryonic stem cells to modern science and medicine rests largely on the fact that they are pluripotent. This means that they have the ability to form into any cell necessary within the

Stem Cell Research Controversy: Argumentative Essay

1152 words - 5 pages The advancement in technology has lead to the treatment of many diseases. Stem cell research has provided hope and has brought optimism among the scientists and doctors in curing the patients who suffered or died due to the once called "untreatable" diseases decades ago. Stem cells are the ones which can develop into any type of a body cell including the cells of blood, liver, brain, muscles, and many more. They are found in adult bone marrow

Advantages of Adult Stem Cell Therapy

1593 words - 6 pages The advancement of biomedical research has improved stem cell therapies immensely. There is a lot of unnecessary debate about the advantages and disadvantages of adult stem cell therapy versus embryonic stem cell therapy, which could be avoided if people were more knowledgeable of both therapies. Adult stem cell therapy is far superior to embryonic stem cell therapy because it avoids ethical concerns, the patients can use their own cells, and

Even with the future looking optimistic, stem cell research has many risks involved, not to mention a mass of controversy around the world. Stem cells are the foundation for every organ and tissue in a living organism’s body. They were given the name “stem cell”, because they are what all cells stem from. Stem cells are unlike any other cells because

Ethical and Beneficial Replacement for Embryonic Stem Cell Research

Research involving cells of all types demands the attention of scientists in search of new discoveries in medicine, but embryonic stem cell research sparks a controversy that only an alternative solution can resolve. Embryonic stem cell research should cease due to the fact that it eliminates a human being and research involving adult and IPS cells should supersede it because of the obvious benefits each

As with any debate there are two sides to the issue. Scientific researchers want to expand their research into emerging fields like stem cell research in hopes of bettering medicine for the future. Human right activists and some religious groups are against this type of research because the
