PRESS
RELEASE: FEBRUARY 2, 2004
Subject:
Results of first ever attempted embryo transfer of a clone human
embryo
Professor
Panos Zavos announced to an audience in London on January 17th,
2004 that his team had taken an egg from a 35-year-old woman, inserted
her husband's genetic material, and transferred the resulting embryo
in her womb. If the attempted embryo transfer and pregnancy was
successful, it would result in the birth of a child genetically
identical to its father and without any significant genetic contribution
from its mother, other than the mitochondrial DNA present in the
enucleated oocyte obtained from the mother.
The
attempt to create the world's first cloned human being was a bold
step taken by Professor Zavos and his team. During the press conference
Dr. Zavos said that "he was now waiting to see if the procedure
led to a full pregnancy, but that there was a 70-80% chance that
would not happen. He stated further "I do not have a pregnancy
to announce. Stand-by two or three weeks when we will know more,"
he cautioned the conference.
During
the press conference Dr. Zavos indicated that his team had taken
skin cells from the woman's husband, then via extensive tissue culture,
they were able to transform the cells into fibroblasts, which they
used as the source for SCNT where they fused the fibroblast with
an egg from the woman. It was understood, the egg had already had
its own genetic material removed (enucleated), so the resulting
embryo carried only the nuclear material from the father and therefore
genetically identical to the father. As Dr. Zavos stated during
the press conference the father could not produce sperm, hence the
need for the couple to receive fertility treatment.
Dr.
Zavos during the press conference did not provide any details of
the woman's origin or the date of the embryo transfer, but confirmed
the process did not take place in the UK, US or Europe. He also
did not provide any details regarding the procedure. Professor Zavos
indicated during the press conference that his team has the expertise
and the know-how to monitor the pregnancy and to minimize risk.
He went further "they feel quite confident they can execute
such an effort," he said.
Professor
Zavos in a responsible and professionally correct manner called
on world governments to get involved in the cloning process by producing
guidelines and adequate restrictions under which it could be carried
out by responsible practitioners. "They had better start developing
guidelines because it's too late to ban it, it's too late to outlaw
it," he said.
PREGNANCY
RESULTS
We
have recently run quantitative measurements of Beta hCG during the
second week and repeated the measurements during the third week
following the embryo transfer and the results were negative. The
results indicated that no pregnancy resulted from the first ever
attempted embryo transfer of a cloned human embryo. The materials
and methods used to produce the transferred cloned embryo along
with relevant clinical data will be published in a peer reviewed
refereed journal as a "Case Report" in the near future.
Professor Zavos and his team are dedicated and will continue their
efforts in producing more cloned human embryos for reproductive
purposes as he stated during his press conference in London: "successful
or not, we are going to do another one and another one and another
until we succeed." |
