...method the researchers in Japan and Wisconsin used to arrive at stem cells involves transferring four genes into the genome of a mature cell through virus. These four genes produce factors that “reprogram” the mature cell’s genome to a stem-like state. No viable embryo, therefore, is either created or destroyed—which is the main qualm of conservative opponents of the research...
Although the produced cells seem to recapitulate many of the properties of embryonic stem cells—including the ability to form cell types of each of the three major types in the human body—many of their major caveats seem to have been ignored. Statements that claim that embryos will never have to be sacrificed to create stem cells again are irresponsible and may well prove to be entirely incorrect...
...fruition.” Far from helping the recent studies “come to fruition,” Bush’s policy decisions’ only effect has been to hinder the field of regenerative medicine as a whole, particularly in the United States. Indeed many stem cell scientists have left the country to pursue their research in nations more hospitable to their work...
There is no doubt that the promise of stem cell technology for the curing of many of the worst diseases to afflict the human race cannot be overstated. But with large possibility comes a duty to be skeptical and cautious. It would be foolish for anyone to construe the recent breakthroughs as a reason to discontinue research on embryonic stem cells or to give up the fight to reverse President Bush’s moratorium on the creation of new stem cell lines with federal funding. The new stem cells have not been proven equivalent to true embryonic stem cells...
...meantime, scientists, from the Harvard Stem Cell Institute to Singapore, studying embryonic stem cells should be encouraged and restrictions on their work minimized...
