An excerpt of a letter signed by Cardinal Francis George, President of the United States Conference of Catholic Bishops, sums the arguments:
The embryonic stem cell policy initiated by President Bush has at times been criticized from both ends of the pro-life debate, but some criticisms are based on false premises. The policy did not ban embryonic stem cell research, or funding of such research. By restricting federally funded research to cell lines in existence at the time he issued his policy, he was trying to ensure that Americans are not forced to use their tax dollars to encourage expanded destruction of embryonic human beings for their stem cells. Such destruction is especially pointless at the present time, for several reasons.
- First, basic research in the capabilities of embryonic stem cells can be and is being pursued using the currently eligible cell lines as well as the hundreds of lines produced with nonfederal funds since 2001.
- Second, recent startling advances in reprogramming adult cells into embryonic-like stem cells – hailed by the journal Science as the scientific breakthrough of the year – are said by many scientists to be making embryonic stem cells irrelevant to medical progress.
- Third, adult and cord blood stem cells are now known to have great versatility, and are increasingly being used to reverse serious illnesses and even help rebuild damaged organs. To divert scarce funds away from these promising avenues for research and treatment toward the avenue that is most morally controversial as well as most medically speculative would be a sad victory of politics over science.
