Advancements in medical technology has allowed for a new understanding of stem cells and further developments in research. The use of stem cells in regenerative medicine may hold significant benefits for those suffering from degenerative diseases. To avail such advancements in stem cell research could see the alleviation or complete cure of afflictions that take the lives of millions worldwide each year. (McLaren, 2001) A stem cell 1 is able differentiate into any somatic cell found in the human body, including those identical to itself.

Differentiation is a cellular process whereby a stem cell will divide into a specialised cell, for example a neuron2. To harness the unique cellular function of a stem cell could mean the cultivation of entirely new organs; saving countless lives and resolving acute organ transplant shortages. (Healey, 2007) Although stem cell research poses a considerable breakthrough in regenerative medicine, it raises serious ethical controversy. A specific type of stem cell used in regenerative research is an embryonic stem (ES) cell; harvested through the destruction of human embryos. (Hurlbut, 2006) This poses a significant ethical dilemma, as ES cells are sourced from pre-implantation embryos leftover from In Vitro Fertilisation (IVF). The destruction of embryos is seen by many as an abuse of human life, an exploitation of those that are living, but cannot decide their own fate. (Masters, 2005) Before ES cell research is to make a positive impact on modern medicine and the global scientific community, this ethical predicament must first be considered.

Embryonic stem cell research will allow for an emerging era of medicine, where researches will be capable of providing a cure for many of todays degenerative diseases. ES cell research offers hope to those suffering from some of todays most common and severe diseases, including; cancer, heart disease, diabetes, cystic fibrosis and Parkinson's Disease. (Pera et al, 2004) The bodies specialised cells, a product of stem cell differentiation, cannot be replaced through natural regeneration. The further exploration of ES cell research will allow scientists
to harness stem cell differentiation and compensate for the bodies inability to regenerate specialised cells. (Fuchs, 2008) For example, ES cells hold the potential to regenerate the spinal cord. Common and debilitating injuries to the spinal cord result in paralysis, more accurately known as paraplegia and quadriplegia. ES cells
may be used to repair an impaired spinal cord, restoring movement and quality of life to those suffering from paralysis. (Rosenfeld et al, 2004) The prospects for regenerative spinal cord repair is one of the many positive outcomes of ES cell research if exploration is allowed to continue.

Ethicists often advocate for the use of human embryos in ES cell research due to their fate after successful IVF
treatment. With the successful fertilisation of an IVF patient, remaining embryos that...

1153 words - 5 pages Embryonic Stem Cell ResearchA new advance in technology that seems to make itself the topic of talk show round tables and dinner tables is embryonic stem cell research. With supporters and detractors on both sides of the issue, it is clear that this controversial procedure will continue to encourage debates whether it be on television, in newspapers, or just between humans in general. The ingenuity of this scientific advancement shows promise in

1414 words - 6 pages President Obama acted appropriately when he signed legislation to reverse the ban restricting use of use of embryonic stem cells for research. The benefits of embryonic stem cell research for the advance of medicine are far greater than moral and ethical concerns raised by many. Using unwanted embryos in the blastocyst stage for research enables scientists to perform valuable studies that could ultimately result in the development of a cure for

Human Embryonic Stem Cell Research

4193 words - 17 pages Human Embryonic Stem Cell Research Many scientists believe that research on human embryonic stem cells, components of human embryos created in laboratories, will eventually yield cures to a number of devastating human conditions including juvenile diabetes, Parkinson’s disease and spinal cord injuries. On August 9, 2001, President George W. Bush announced he would permit federally funded research on existing stem cells lines derived from

Some of these cells retain the ability to become any type of cell located in the body. They act as a kind of reservoir, one that provides new cells to replace those that are damaged or lost. At the foetal stage of development, they are known as ‘Embryonic Stem Cells.’ These cells are at the heart of the controversy surrounding stem cell research because a

1176 words - 5 pages many ethical theories that support and oppose it. I am going to try to touch on a few of these theories and how they apply to the research done on human embryonic stem cells. Human embryonic stem cell (HESC) research involves removing tissue from the aborted embryo to get cells to study. This research can potentially help treat Parkinson’s disease, Alzheimer’s disease, Stroke, Diabetes (Type 1), Birth Defects and Spinal Cord Injuries. I can

2167 words - 9 pages , government regulations have been imposed and the issue so hotly debated that the field of stem cell research has nearly turned into the same kind of scenario faced by doctors at abortion clinics. The lack of suitable stem cells is what holds human embryonic stem cell (hESC) research from progressing further. In order to allow hESC research to develop, more hESC lines should be approved for clinical studies because research has shown that the longer

Embryonic Stem Cell Research – Ethical or not?

1183 words - 5 pages are tough questions faced by both the scientists engaged in the research, as well as the legislators who define the laws governing such research. Although many would agree that embryonic stem cell research holds the potential of developing cures for a number of illnesses that affect humankind, if such research is performed at the cost of destroying a life it should therefore not be pursued. As noted earlier few scientific advances have generated

1357 words - 5 pages “I am in favor of stem cell research. In fact, I don’t know anyone who is opposed,” says Dr. David A. Prentice in the opening paragraph of his article, “The Real Promise of Stem Cell Research.” “Embryonic stem cells are cells obtained from an embryo in the blastula phase, when they are still only a few days old. Because they have only begun to differentiate, these cells have the capability of developing into any cell in the human body. This fact

The Debate Concerning Embryonic Stem Cell Research

1515 words - 6 pages One of the most heated political battles in the United States in recent years has been over the morality of embryonic stem cell research. The embryonic stem cell debate has polarized the country into those who argue that such research holds promises of ending a great deal of human suffering and others who condemn such research as involving the abortion of a potential human life. If any answer to the ethical debate surrounding this particular

Years later, in 1998, a method to extract stem cells from human embryos and grow the cells in the laboratory was discovered. The main purpose was to use the cell's ability to regenerative as a method of treating diseases. As time went by, people started to oppose the idea of using embryonic stem cell for research. So, funding that helped continue research on

The Controversy over Embryonic Stem Cell Research
