Nearly two decades have passed since the
birth of Dolly the sheep, a clone manufactured through a process known
as somatic cell nuclear transfer (SCNT). Since that time, the prospect
of human cloning has been eagerly—or fearfully anticipated—throughout
the world. Indeed, in 2004, Korean scientist Huang wu-Suk became
generated world headlines when he claimed to have created the first
human cloned embryos and derived embryonic stem cells from them.
It later turned out that he had done no
such thing. Huang was a charlatan. But now, the very deed that briefly
made him the world’s most famous scientist has actually been
accomplished, and you can hear the crickets chirping.
Why the striking difference in attention paid to an epochal story?
When
Huang claimed to have successfully cloned human beings, it set off a
political firestorm, with human cloning proponents and opponents
debating hotly over how and whether to regulate human cloning, or
even—as I advocate—to ban it altogether.
Wanting to prevent another public
brouhaha, the scientists who actually did do human cloning—and the
Science Establishment—generally avoided using the C-word in the popular
media—instead claiming merely that stem cells were obtained from
“unfertilized eggs.” Thus, the
Wall Street Journal reported:
Scientists have used cloning
technology to transform human skin cells into embryonic stem cells, an
experiment that may revive the controversy over human cloning. The
researchers stopped well short of creating a human clone. But they
showed, for the first time, that it is possible to create cloned
embryonic stem cells that are genetically identical to the person from
whom they are derived.
That description missed an essential—and morally crucial—element: SCNT does not create stem cells, it manufactures a human embryo via asexual reproduction, from which stem cells can be derived just as with a fertilized embryo.
To better understand what is going on, let’s take a brief look at how SCNT is accomplished:
- First, take a skin or other cell (Dolly came from a mammary gland
cell, hence her naming as something of a joke after Dolly Parton);
- Remove the cell’s nucleus;
- Next take an egg and remove its nucleus;
- Place the skin cell nucleus where the egg nucleus used to be;
- Stimulate with an electric current or other means;
- If the cloning works, the properties of the egg transform into a one-celled embryo just as occurs after fertilization.
Once the embryo arises, the cloning is over. If all goes well, the embryo will develop like a natural embryo.
The next question involves what to do
with the living human life that was created. If the nascent human being
is to be destroyed for experimentation—as in this experiment—the process
is often called therapeutic cloning. If the intent is to implant in a
womb and bring a child to birth, it is often called “reproductive
cloning.” Either way, the actual cloning process is the same.
Indeed,
when the scientists talked to each other in the science journals, they
were far more candid about what had been done. Thus, in
the paper published in
Cell,
in which the scientists announced their cloning breakthrough, they
acknowledge to having created “SCNT embryos” From the study (my
emphasis):
Activation of embryonic genes and transcription from the transplanted somatic cell nucleus are required for development of SCNT embryos
beyond the eight-cell stage. Therefore, these results are consistent
with the premise that our modified SCNT protocol supports reprogramming
of human somatic cells to the embryonic state.
Why is this important morally? Scientists have manufactured human life.
In a sense, it is reproduction by replication—creating a new human
being designed to have a specific genetic makeup in the mirror image of
the person cloned. Even if the technique remains limited for use in
seeking biological knowledge and searching for potential medical
treatments, those beneficent ends will come at the very high ethical
price of manufacturing human life for the purpose of destroying and
harvesting it like a corn crop.
But it won’t end there. Human cloning is
the essential technology
to developing potential Brave New World technologies, such genetic
engineering, creating human/animal chimeras, gestating cloned fetuses in
artificial wombs as a means of obtaining patient-compatible organs, and
eventually, the birth of cloned babies. (We have already seen
advocacy for such fetal farming among a few bioethicists, and
experiments have already been conducted on late term aborted female fetuses to determine whether their ovaries can be harvested to obtain eggs for use in research.
Not only that, but human cloning heightens the risk that vulnerable women will be exploited for their eggs—the
essential ingredient
in SCNT—one egg per cloning attempt. Thus, it isn’t surprising that as
the rumors about successful human cloning were swirling through the
science community,
a bill was introduced
in the California Legislature—A.B. 926—that would permit universities
and their biotech partners to pay women for eggs to be used in
scientific research.
As the CBC documentary
Eggsploitation vividly demonstrates, supplying eggs can be dangerous to the woman’s health and fecundity.
This is the bottom line: Human cloning has been accomplished. We will either deal with it, or it will deal with us.
