Excerpt from Term Paper:

And perhaps most importantly of all, the UW researchers continue, stem cells "...provide our only window to the earliest stages of human development and, after differentiation, access to more specialized cells that could vastly improve our understanding of the onset of cell-based diseases, and perhaps ways to prevent them."

Among the diseases that may be able to be treated - and even cured - through stem cell research are Parkinson's Disease, Alzheimer's, diabetes, heart disease, stroke, spinal cord injuries, burns, and more. How many people could be helped, even relieved of enormous suffering, through successful stem cell science is unknown, but certainly there are millions who cry out for help.

Medical researchers highly value stem cells because they can develop into many types of human tissue," according to an article in the Washington Post (Babbington, 2004). Stem cells "...hold promise for treating spinal injuries among several other afflictions," Babbington explains. And where the controversy enters into the picture is the fact that some stem cells can be obtained from "adult tissues, but more versatile cells come from human embryos," embryos which are frozen and left over at fertility clinics.

Many researchers currently working on this science use stem cells "from embryos at an early stage of development, about five days after fertilization," Brainard writes. At five days "the embryo numbers only about 200 cells," and all of them are "capable of specializing into all of the cells that make up the body," including such key parts as brain neurons and heart muscle, Brainard explains.)

And so, if using human embryos is so controversial, why not take stem cells from adults? The UW Stem Cell Center answers that question by pointing out that currently, there are indeed a series of approaches in experimental stages "...that utilize mature stem cells (such as blood-forming cells, neuron-forming cells and cartilage-forming cells)." The problem though is that "...because adult cells are already specialized, their potential to regenerate damaged tissue is very limited."

For example: the only thing skin cells will become is skin, and cartilage cells only become more cartilage. "Adults do not have stem cells in many vital organs," the UW explanation continues, "so when those tissues are damaged, scar tissue develops. Only embryonic stem cells, which have the capacity to become any kind of human tissue, have the potential to repair vital organs."

Another shortcoming of adult stem cells is that they do not proliferate in culture like embryonic stem cells do. In fact, "adult stem cells are difficult to grow in the lab and their potential to reproduce diminishes with age." Hence, useful, functioning amounts of adult stem cells may prove to be "difficult to obtain." very recent and positive research result on stem cell science

According to an article in the Washington Post (Weiss, 2004), scientists in Haifa, Israel (Izhak Kehat and Lior Gepstein), working in the Technion-Israel Institute of Technology, have recently made some startling discoveries with reference to stem cells growing into heart muscles. In one of their experiments, the scientists grew masses of stem cells in lab dishes, isolating those stem cells that "were spontaneously developing into heart cells," which they could detect because the stem cells morphing into heart cells "were pulsing in unison, as heart cells are apt to do."

The Israeli researchers then placed a mass of about a million human stem cells (about the size of the head of a pin) into a lab dish with heart cells from rats. At first, the cells of the rat species and of the human species "beat at different rates," but within 24 hours of being in the same lab dish, "the combined masses of cells coordinated their pulsing into a single rhythm."

What does this prove or portend for the use of stem cells? Could stem-driven heart cells assist in setting the pace of a heart in a live animal? To take their experiment a notch further, the team of scientists "threaded a probe into the hearts of 13 pigs," making a tiny burn in the area that regulates the beating of the pig's heart. That burn caused a severe (and permanent) slowing of the pig's hearts, mimicking the rhythm disorder that cause result from a heart attack in a human. Then the scientists "injected about 100,000 of their human embryo-derived heart [stem] cells" into the slowed-down pig's hearts, and soon 11 of the 13 burn-damaged pig's hearts "returned to faster heart rates," according to Weiss's report.

What does this prove? it's just a "proof of principle," said Gepstein, though it's not as though people will be lining up for "biological pacemakers" any time soon.


In a phone interview with an Alzheimer Association staff person named "Elizabeth" (they don't give last names, she said) she was asked if her organization supports stem cell research. "I will read to you the position of our national Board of Directors, which made this official position statement in June, 2004," she said. "In keeping with its mission to eliminate Alzheimer's disease, the Alzheimer's Association opposes any restriction or limitation on human stem cell research, provided that appropriate scientific review, and ethical and oversight guidelines are in place.'"

  • Stem Cell Research the Issue

    At this point it should be clear that there are no good reasons to oppose the federal funding of embryonic stem cell research and only good reasons for supporting. Opposition to the federal funding of embryonic stem cell research can only be justified by an appeal to unreasonable and arbitrary moral standards based not on logic, reason, or concern for human well-being, but rather on the dictates of outdated and

  • Stem Cell Research Utilizing Stem

    There are some embryos who are outside of this environment, and will not grow to be people, and are therefore suitable to use in stem cell research. There is a degree of moral ambiguity related to the debate of stem cell research -- based on the conception of when life actually begins. The acknowledgement of this aspect of the debate is acknowledged on both sides, and is a point of

    but, Cuomo continued, Bush's position "…remains a minority view" (Hurlbut, 822). Christine Todd Whitman, who served Bush as administrator of the Environmental Protection Agency in Bush's first term (she served from January 2001 to May 2003), and was the first female governor of New Jersey, supported embryonic stem cell research. Whitman noted in her book that right after Bush was re-elected in 2004, Christian conservative organizer Phil Burress was heard

    The media might present an issue as fact without verifying its truth via the appropriate channels, while the public in turn is eager to accept as fact what is presented to them, as this is much more simple than researching the issues themselves, or even simply verifying the truth of a stated fact. Furthermore, the authors hold that simply educating the public regarding issues of scientific controversy is far

    In the words of Obama, "Today, with the executive order I am about to sign, we will bring the change that so many scientists and researchers, doctors and innovators, patients and loved ones have hoped for, and fought for, these past eight years: We will lift the ban on federal funding for promising embryonic stem cell research," President Obama further said. "We will vigorously support scientists who pursue this

    Conclusion This Technology Should Be Regulated and Controlled by Government There is not really much argument that stem cell research, regardless of its origin as embryonic or otherwise should be controlled to some degree by the government as the development of this research demonstrates a potential for abuse that is startling and could essentially be highly abused. The abuse of this type of research would likely be sourced in the desire of
