New Support for Stem Cell Research Seen in U.S. Congress

Stem Cells

In April of 2004, a letter bearing 206 signatures of Members of the United States House of Representatives was sent to President George Bush, asking him to increase the number of human embryonic stem cell lines that should be eligible for public funding.

Now, 58 Members of the U.S. Senate are backing their colleagues in the House. On June 4th, they sent a letter to the White House saying that the number of available lines is fewer than anticipated. The letter noted that most, if not all, of the cells President Bush previously approved are unusable for therapeutic purposes because of the specific way they were handled in the lab. Furthermore, the letter said that the U.S. has given up its accustomed place as the leader in biomedical research.

In essence, the signers are trying to get the President to change his mind about stem cell lines used for research so that Congress does not have to create a legislative solution.

Particularly in an election year, Republicans do not want to challenge Bush with new legislation, even though some of the most strident conservatives in the party are now in favor allowing scientists to study cells from embryos that were frozen as part of assisted reproduction techniques. And almost certainly it would serve neither party’s interest to have an intense floor debate or vote as the Presidential campaign heats up.

More pressure to change the existing Bush policy is expected with the death of former President Ronald Reagan, who died this week of Alzheimer’s disease. His wife, Nancy, has called for the Administration to make more stem cell lines available for federally funded research on diseases like Alzheimer’s and Parkinson’s.

The White House and the National Institutes of Health (the major funder of biomedical research in the United States) have both said that the Administration will stay with the current policy, established in 2001, which a majority of the scientific community finds completely unworkable.

Below is the full text of the Senate’s letter, followed by a summary of the legislation to ban human reproductive cloning and allow nuclear transplantation research to continue.

Letter From 58 Senators to President Bush

June 4, 2004

The Honorable George W. Bush
The White House
Washington, DC 20500

Dear Mr. President:

We write to urge you to expand the current federal policy concerning embryonic stem cell research.

As you know, embryonic stem cells have the potential to be used to treat and better understand deadly and disabling diseases and conditions that affect more than 100 million Americans, such as cancer, heart disease, diabetes, Parkinson’s, Alzheimer’s, multiple sclerosis, spinal cord injury, and many others.

Embryonic stem cells can be derived from in vitro fertilized (IVF) embryos that are developed in excess of those needed for the procedure used to enable infertile couples to have children. The IVF process results in more embryos than are needed by the couple. There are estimated to be more than 400,000 IVF embryos, which are currently frozen and will likely be destroyed if not donated, with informed consent of the couple, for research.

We very much appreciate your words of support for the enormous potential of this research, and we know that you intended your policy to help promote this research to its fullest. As you know, the Administration’s policy limits federal funding only to embryonic stem cells that were derived by August 9, 2001, the date of the policy announcement.

However, scientists have told us that since the policy went into effect more than two years ago, we have learned that the embryonic stem cell lines eligible for federal funding will not be suitable to effectively promote this research. We therefore feel it is essential to relax the restrictions in the current policy for this research to be fully explored.

Among the difficult challenges with the current policy are the following:

• While it originally appeared that 78 embryonic stem cell lines would be available for research under the federal policy, now, more than two years after August 9, 2001, only 19 are available to researchers.

• All available stem cell lines are contaminated with mouse feeder cells, making their therapeutic use for humans uncertain.

• Scientists are reporting that it is increasingly difficult to attract new scientists to this area of research because of concerns that funding restrictions will keep this research from being successful.

• Despite the fact that U.S. scientists were the first to derive human embryonic stem cells, leadership in this area of research is shifting to other countries such as the United Kingdom, Singapore, South Korea, and Australia.

Mr. President, we know that you have been a strong supporter of medical research and share our commitment to curing disease and alleviating human suffering. We would very much like to work with you to modify the current embryonic stem cell policy so that it provides this area of research the greatest opportunity to lead to the treatments and cures for which we are all hoping.

Summary of the legislation to ban human reproductive cloning and allow nuclear transplantation research to continue:

  • Impose a sentence of up to 10 years in federal prison for anyone even attempting to a clone a human being, and establish a minimum civil penalty of $1 million or three times the gross profits resulting from the violation, whichever is greater;
  • Mandate that eggs used in this research be unfertilized;
  • Prohibit the purchase or sale of unfertilized eggs - to prevent "embryo farms" or the possible exploitation of women.
  • Impose strong ethics rules on scientists, mandating informed consent by egg donors; review of any nuclear transplantation research by an ethics board; and include safety and privacy protections.
  • Prohibit any research on an egg cell after 14 days—when that cell begins to divide and when cell differentiation begins.
  • Require that all egg donations be voluntary, and that women who donate eggs are compensated minimally.
  • Require that nuclear transplantation occur in labs completely separate from labs that engage in in vitro fertilization.
  • Prohibit the export of eggs that have undergone nuclear transplantation to any foreign country that does not ban human cloning.
  • Any researcher who violates the bill's ethics requirements (even without attempting to clone a human) will face civil penalties of up to $250,000 per violation.
