Experts debate the latest developments in the controversial practice of cloning human cells. |
|
Michael West, who heads Advanced Cell, described the accomplishment on NBC's "Meet the Press."
Critics said that's not enough to extract embryonic stem cells, which are normally derived from embryos that are four to five days old, and that contain up to several hundred cells, but the advanced cell researchers have vowed to press ahead until they succeed in producing embryos that will in fact yield stem cells. Advanced cell's actions amounted to an indirect challenge to President Bush's policy on federal funding for embryonic stem cell research.
MICHAEL WEST: All 60 cell lines that the president talked about having the federal government fund research on are great for in the laboratory; they aren't useful in patients because the patient would reject them. SUSAN DENTZER: But today the president said he opposed the company's actions as well. REPORTER: An important line has been crossed with the attempt to clone a human being by a private laboratory. Do you think there is any way to put this genie back in the bottle?
SUSAN DENTZER: The president said he supported legislation passed by the House of Representatives last summer to ban both therapeutic and reproductive cloning, and today some Senators said they would try to pass similar legislation soon.
SUSAN DENTZER: But with still other lawmakers in favor of reaping the benefits of stem cell research, the outcome of a congressional debate is far from certain. |

Dr. Kass, we just heard the president say that he believes that creating life in order to destroy it is what is at the center of this, and that it is wrong. Why don't we start with you. Is he right or wrong?
The Congress of the United States by a margin of over 100 votes, including 60 Democrats, enacted legislation designed to stop all human cloning from the very start. Here we have a group of entrepreneurs who, for their own good reasons and confident that their good intentions are sufficient unto the day, crossed this line in defiance of all of these things. I don't think that's the right way for us to proceed. GWEN IFILL: Professor Green, has this moral boundary been crossed?
GWEN IFILL: Explain that distinction because you're talking about a distinction about how the stem cells would be used not what they could be used for. RONALD GREEN: Well, I think that the critical issue here is to really have firm regulations and rules and laws in effect that prohibits reproductive cloning. I think that can be done. I actually would hope and I know that the scientists at Advanced Cell Technology hope that the Senate and others will go ahead and prohibit reproductive cloning in the future and criminalize that behavior. Nobody is really arguing that point seriously in the scientific community. But what we're saying is don't prevent this research, which puts a limit on how far you can go with these cloned organisms, and that can produce lifesaving tissues, nor organs for individuals who are seriously ill, to prohibit therapeutic cloning in the effort to stop reproductive cloning is going too far.
LEON KASS: It is a distinction that makes some sense though the name therapeutic cloning is at the moment science fiction. One should be very careful about taking advantage of the hopes of the people seriously ill and their family members to promise them the moon. We do not at this point have a single instance of a human disease cured by stem cells, whether from embryos or from adults. We do not have a single animal model in which cells or stem cells derived from embryonic clones, say, of mice have been used in fact to cure those diseases. The idea that 50, 75 years down the road each of us will be able to produce our little embryonic clone so that we can get our own tissue back is pie in the sky at the moment and would involve among other things something not much discussed the enormous co-modification of women's reproductive tissue. Where will we get all these eggs to produce these vast number of embryos to extract these cells. |

GWEN IFILL: Let me address that point to Professor Green, because as an ethics advisor to this group you oversaw the plan with which they put in place to harvest women's eggs for this experiment. What was your role? GWEN IFILL: You're not talking about donation in this case - excuse me for interrupting. You're talking about $4,000, right, payment? RONALD GREEN: Women are in fact compensated at the same rate that is paid for those who provide eggs for reproductive purposes. And that's partly conceptualized in terms of the time and effort. This is a very invasive procedure. They have to inject themselves with medications for days on end and undergo a procedure whereby the eggs are harvested. It works out to a very modest payment for them. I want to repeat that one of the things that we are finding in the questionnaires that we put to these women when we ask them why they're doing it, overwhelmingly they say, "I want to make a contribution to the advancement of medical science." And I don't see why women should be prohibited from doing that. I don't think why that's CO-modification GWEN IFILL: Well, Dr. Kass, let's talk about the advance then of medical science. From what you have read about what Advance Cell Technology has released today or yesterday in this report, do you believe that they have actually made strides in medical science? Is there proof that what they have discovered actually is going to take us to the next step?
Once cloned embryos are available in the laboratory having been produced for research nothing prevents them from being used for reproductive purposes. These activities take place protected by industrial secrecy. When they move over into the in vitro clinics, they will be protected by the secrecy of the doctor-patient relationship and should an illicit, so-called illicit clonal pregnancy be discovered, no one is going to move to force the woman to abort. It seems to me that before anyone starts down the road to creating any kind of cloned embryos, we should be very confident that we not only can imagine effective bans on reproductive cloning but we actually have some effort to put those in place. To this point we haven't done so. |

| Prematurely published findings? | ||||||||||||||||||||

GWEN IFILL: Professor Green, this experiment that was written about that we're all talking about here didn't actually produce a currently living human embryo. Did the researchers decide to publish their findings prematurely?
GWEN IFILL: Professor Green, the debate here in Washington is about the public role and public limits being placed on this kind of research. Do you think that the private sector is racing ahead of the public debate on this subject? RONALD GREEN: Well, I think we as a society for better or worse have come up with some public sector rules, which are very restrictive. Many scientists and ethicists don't agree with the public sector rules on stem cell research. That's fine. That's the public sector. That's where the majority have voted. It doesn't seem right to me, however, now to extend that as well to the private sector where people are not using public resources, they're using their own resources and trying within the limits of available and existing law to save human lives. I don't see why that should be prohibited. GWEN IFILL: Dr. Kass, your response to the same question given that the House has passed the bill which would ban all public and private human cloning experimentation. LEON KASS: For the most part it seems to me we do in general a good relation between public and private initiatives here. But let's not kid ourselves. We're standing at a critical moment in human history. It is given to this generation to decide whether and how quickly we mean to move down the road toward the brave new world. With respect to decisions like that, I don't think that this should be business as usual with a naive hope that we can somehow manage the untoward consequences should they occur. This would be like saying that someone who today... 50 years ago had decided that he was going to undertake the splitting of the atom because he was interested in the peaceful uses of atomic energy but wasn't interested in making bombs. Question: Should that have been a decision left to private entrepreneurs or should that be a public decision? I think we're facing a momentous decision regarding the human future, and it is not for business as usual. The public should be heard. GWEN IFILL: A slippery slope argument?
GWEN IFILL: Let me pose that same question about the slippery slope to Professor Green. RONALD GREEN: Well, I think there are risks and there are dangers, but the slippery slope goes in other directions. If we prohibit therapeutic cloning now, we also prevent the development of all these dramatic and potentially remarkable new therapies and cures. I would argue that we should now take the step of drawing the line at reproductive cloning. That line is very clear. We can criminalize that. Michael West and the people at Advanced Cell Technology will not disobey that rule. They're not going to bankrupt their company. Why is it appropriate to ban the entire area and not reproductive cloning? GWEN IFILL: Thank you both for joining us. |
