...Boston Globe recently reported about a stem cell clinic in the Ukraine which charges high sums for sketchy treatment. Giving patients false hope for successful treatment is reprehensible. Advocates of stem cell research have a responsibility to acknowledge that stem cell medicine is not available today. But even worse than providing false hope is to deny all hope that stem cell medicine may soon become a reality. This is the route on which America is currently embarked...
...problem with today’s stem cell debate is that both advocates and critics sometimes convey a perspective on the issue which may be alienated from its practical reality. At a time when critical policy decisions are made, the need is great to clearly communicate the science of stem cells and to test the controversy against reality. On close view, stem cell technology presents itself as a medical innovation which can be regulated given informed policy choices...
...range of medical afflictions result from the failure of specific kinds of cells to produce a needed chemical or from the death of cells themselves. Replacement with healthy cell tissue would be an ideal treatment. Stem cells, which have the ability to differentiate into many different types of cells, can be stimulated by researchers to develop into the specific tissue needed by the patient. Scientists hope that by using this approach, stem cell medicine will become a reality in the near future...
...most useful stem cells, those able to differentiate into any type of human cell, are derived from embryos which are five to six days into development. Stem cells derived from adult tissue may also offer potential for treatment, but—except for adult stem cells of the blood—our understanding of embryonic stem cells is much more developed. Embryonic stem cells have been studied for over twenty years, and offer the fastest route to scientific progress today...
...LOWER THEIR voices, become more thoughtful and almost reasonable when fielding questions about social issues? It happened in the vice-presidential debate when gay marriage was raised, and it may well have saved President Bush from blowing a gasket in the second presidential debate. His last half hour, when stem-cell research and abortion were discussed, was his best. He stopped huffing about, slipped into Man of God mode. He even accused Kerry of being a flip-flopper in a more thoughtful...
