Attempts to
clone human embryos, to implant clonal embryos and bring them
to term are almost certainly underway in the US at the present
time. Advanced Cell Technologies (ACT) publicly promoted its efforts
in both somatic cell nuclear transfer and parthenogenesis in what
many thought a shameless effort to pump up their stock prices.
Drs. Panos Zavos and Severino Antinori have been no less vociferous
in seeking publicity, and investors, in their efforts at producing
a baby through implantation of a clonal embryo. Because nuclear
transfer techniques could be carried out in most well equipped
IVF clinics, how many other such efforts unpublicized
and unnoted may be underway is anybodys guess.
The chances are that eventually it will be tried.
All this goes
on because, despite continued public concern and outcry since
the cloning of the sheep Dolly in 1997, the US Congress has failed
to enact legislation to ban or regulate human cloning through
any means.
In July 2001,
the House of Representatives passed HR 2505, the Human Cloning
Prohibition Act which bans any attempt to clone a human
embryo and establishes severe criminal and civil penalties. This
bill was sent to the Senate for consideration in late July. Congress
left on its second two-week break in six weeks on March 22, 2002,
while cloning legislation was still in a holding pattern in the
Senate, behind energy, the budget, and several other pending matters.
Looming large after the break are the annual appropriations bills
that may delay action on cloning until May or later.
Discussion in
Senate hearings has been marked by an effort to draw a distinction
between embryos cloned for the purpose of implantation and gestation
and those created for the purpose of research. One Senator even
insists that if you conduct somatic cell nuclear transfer which
she calls SCNT (pronounced skint) to produce stem
cells for research there is no embryo involved. This is what has
led, in part, to the strange definition of human cloning found
in S. 1758, the Feinstein-Kennedy bill: The term human
cloning means asexual reproduction by implanting or attempting
to implant the product of nuclear transplantation into a uterus.
Substituting, of course, the terms product of nuclear transplantation
for clonal embryo.
The cloning bills currently active in the Senate are:
1. S. 1758:
Originally co-sponsored by Senators Dianne Feinstein (D-CA) and
Edward Kennedy (D-MA). The Feinstein-Kennedy bill permits creation
of cloned human embryos through nuclear transfer techniques. It
intends to prohibit implantation of such clonal embryos, providing
criminal and large civil penalties for implantation, and to permit
the use of such embryos for research purposes. An analysis of
this bill by the International Center for Technology Assessment's
legal staff indicates that the bill will probably not stop reproductive
cloning and provides for no meaningful regulation of the use of
clonal embryos for research.
2. S. 1893:
Co-sponsored by Senators Arlen Specter (R-PA) and Tom Harkin (D
IA). This bill is a ban on implanting human embryos that have
been created through nuclear transfer techniques into a human
uterus or a "substitute for a woman's uterus. The bill
provides criminal penalties and substantial civil monetary penalties.
However, there are no restrictions or regulations on the creation,
distribution, or sale of human embryos through any technology
or process, until after the instant of insertion, at which point
a criminal act has occurred. [N.B.: A similar bill introduced
early in the session by Senator Ben Nighthorse Campbell (R-CO),
S. 704, has been dormant since its introduction in early April
2001.]
3. S. 1899:
Co-sponsored by Senators Sam Brownback (R-KS) and Mary Landrieu
(D-LA). This bill is a mirror of the House bill and offers a "clean"
ban on the creation of human embryos through nuclear transfer
techniques. The bill provides criminal and substantial civil monetary
penalties for creating a clonal embryo.
Many senators on both sides of the aisle are still undecided.
The press is reporting that a multi-million dollar ad blitz is
underway in targeted states across the country to change the publics
understanding of what cloning means and to convince people that
it is possible to derive stem cells from cells of non-embryonic
origin that are made to behave like embryonic cells. (Perhaps
a "cell activated after somatic cell nuclear transfer.)
In addition, a publicity blitz from the research-industry-academia
complex is promoting the idea that to ban or even slow efforts
to clone human embryos is to deny life saving treatment to millions
of suffering people around the world. Many of the undecided members
of the Senate are waiting for an alternative to the current bills.
Senators do not want to become known as "one of the cloners,"
but equally fear being labeled as obstructing research that might
find a miracle cure for a dreaded disease.
The CRG and
other reproductive health and womens groups, as well as
many social conservatives, oppose all forms of human embryo cloning
for ethical, health, safety, or moral reasons. The progressive
community has additional concerns about cloning human embryos
and using them for research. Environmentalists, consumer groups,
women's abortion rights activists, feminists, childrens
health advocates, and others all want to see the unprecedented
ethical, health, and regulatory questions raised by the idea of
cloning human embryos resolved before any human embryo cloning
is allowed. Following is a summary of the issues included in the
debate. (1)
As a human community,
we have never supported creating any human life form simply for
its exploitation and destruction. There has never been public
acceptance of, or government approval and support for, an industry
of the creation of a human life form solely to harvest it for
spare parts. The most recent poll as of this writing
indicated that over 85% of people in the US oppose the creation
of embryos by any method for the sole purpose of destroying them
for any reason (June, 2001, an International Communications Research
poll on the creation of cloned embryos for the purpose of their
destruction).
As CRG Board
Member Dr. Stuart Newman recently testified at a Senate committee
(2),
if cloned embryos are not sufficient for stem cell production,
there will no doubt be a call for allowing these embryos to gestate
up to several weeks so that stem cells can more easily be garnered.
(3) The ultimate nightmare appears in the use of cloned neo-morts,
brain dead late term fetuses or newborns kept alive
and growing as research tools or sources for valuable human cells
or tissues or as drug test subjects. There must be public hearings
around the country with wide-ranging public participation on this
key ethical issue before any human embryo cloning is allowed.
Those wanting to ban "reproductive" cloning but not
place strict restrictions and controls on cloning human embryos
fail to understand the important relationship between the two.
Cloning human embryos for research could create tens of thousands
of cloned human embryos. With this huge supply of embryos and
an absence of effective oversight and control, it is virtually
inevitable that the legally cloned embryos created
for research will be used for illegal reproductive cloning.
How do we enforce
a ban on the implantation of cloned embryos once they are in the
marketplace? And how will we deal with the issues that arise if
a legally cloned embryo is implanted in a womans womb?
Clearly, the
time for restriction and enforcement is before we allow embryo
cloning. We should enact strict standards for research cloning
if it is found ethically acceptable and necessary, which 1: require
inspection, evaluation and approval for embryo cloning research
by a limited number of laboratories and researchers; 2: mandate
a strict regime of supervision, monitoring and reporting from
the initiation of a proposal for research, until the research
is completed; and 3: require an unbroken record of custody of
each and every cloned embryo from creation to destruction.
There are also potentially serious health risks associated with
embryo cloning. Dr. Irving Weissman, chair of the National Academy
of Sciences committee that prepared a report on cloning and stem
cell research, estimates that it takes 50 human eggs to get one
viable embryo. (4) All of these eggs will need to be harvested
from women.
Egg harvesting
can have significant health impacts on women. Of particular concern
are the super-ovulating drugs, the numerous hormone treatments,
and the extraction process itself. Potential risks include premature
menopause, ovarian cysts and cancers, severe pelvic pain, rupture
of the ovaries, bleeding into the abdominal cavity, acute respiratory
distress, pulmonary embolism, and possible negative effects on
future fertility.
Women who decide,
for whatever reason, to become egg donors or sellers, must be
fully informed about the risks involved. There must be federal
legislation prohibiting the sale of human eggs and monitoring
the health impacts of egg donation prior to any approval for research
embryo cloning.
Cloned human embryos are patentable according to the U.S. Patent
and Trademark Office. In addition, the sale, export, or import
of human embryos is not prohibited. Aside from the aforementioned
safety risks, cloning human embryos for use in research could
turn thousands of women into paid egg factories. If
we allow the patenting and sale of human embryos and human eggs,
we corrupt and demean what it means to be human. There must be
legislation passed banning the sale and patenting of human embryos
prior to any cloning of human embryos for research.
We must wait to see what the US Congress and President Bush will
do with the legislation pending this year. These are issues that
demand careful consideration, extended debate, detailed planning,
and broad consensus before the first actual cloned human embryo
is produced.
The only bill
currently under consideration in the Senate that takes the ethical
issues seriously and provides the time we need to resolve the
critical questions raised by human embryo cloning for our culture
is the Brownback bill that bans the creation of embryos for any
purpose through cloning.
