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, embryos, fetuses, and blood from the umbilical cord (Bailey 100). Stem cell research is the latest advancement in biotechnology which shows how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. This technique has lead scientists to research about the possibility of cell-based therapies to treat disease, which is often referred to as regenerative or reparative medicine.The stem cell formation involves several steps. Early in development, a human embryo is made up of a hollow ball of cells called a "blastocyst". Blastocyst cells divide and form into the tissues and organs of a human body. This process is called as "differentiation". Embryonic stem cells can be grown in the laboratory from blastocysts and made to differentiate into nerve, liver, muscle, blood, and other cells. Scientists believe that this would help to replace cells in diseased organs in human beings. Embryonic stem cells can also be used to test the effects of new drugs without harming animals or people. It is a life changing technique and should be allowed, however, some opponents claim it to be immoral. The opponents claim that since the cells come from embryo, therefore they are alive and extracting these cells means the death of a living organism which is immoral (Ojeda 113).Stem cell research can have a significant impact on regenerative medicine and therapeutic cloning. Regenerative medicine involves the use of stems cells for the growth, either in the test tube in the laboratory or in a human body, for consecutive transplantation. The tissue or organ parts can repair or replace those damaged by abnormalities, aging, disease or injury (Johnson 130). While, therapeutic cloning is a procedure in which cells are taken from a patient (often from skin) and inserted into a fertilized egg whose nucleus has been removed. The resulting cell is stimulated to divide repeatedly to form a blastocyst. Stem cells are then taken out from it and used to grow tissues that are a perfect genetic match for the patient (Bailey 105). These cells can be transplanted in the patients to cure the disorders such as Alzheimer's disease, Diabetes, and Parkinson's disease.Scientists have always been curious about the origin of humans and their evolution. The stem cell research has provided an opportunity to them in a way that they would be able to study human growth and the development of cells in our body with. Stem cells are classified as being pluripotent or multipotent. Stem cells that are pluripotent are...

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

As the controversy rises, it is very helpful to understand and realize what stem cells are and how helpful Edwards 3 they can be in both scientific and medical research. Every cell has the characteristics and code that makes us all different and who we are. Some of us are made to help others, while some are made to rely on others. Hopefully, in the near future we can find new ways to help others that would affect everyone in a good way, which would make us one step closer to a better and perfect universe.

Proponents of stem cells say that until an embryo has not been embedded into the uterus, it does not have a human status and therefore could be used to treat patient who already are persons. Opponents say that since an embryo has the potential to become a person, it should be treated with the same regard as that of a person. For example, Christian Brugger said that stem cell research “would
