PFLI comment: ...Time for the pro-life movement to accept, affirm, and
deal with the disasters caused by acceptance of defective definitions,
compromise and fake science from within and without....all kinds of
artificial life creation abounds, and was helped along from within our
own ranks for decades for those who value more the praise and acceptance
of men rather than doing what is Godly and right...

*So You Think That “Reproductive Cloning” Isn’t Done Yet? Guess Again*
*I. Introduction*
In the article, “The future of fertility” [Jeremy Laurance,
Indepoendent.co.uk, July 17, 2008] -- copied in full below -- the
researchers and IVF specialists claim that “reproductive cloning” is an
exciting if not still a far off possibility – implying that it has yet
to be done.
Wrong. Guess again.
But don’t take my word for it. Check it out for yourself. All one has
to do to realize this is scan the list of references provided here below
(the tip of the iceberg) that document the fact that all sorts of
reproductive cloning has been going on for a long time. Hello – anybody
out there?
*II. “Abortion” now involves asexually reproduced human embryos*
In case it hasn’t occurred to people, once cloned and other asexually
reproduced human embryos are implanted into a woman’s uterus, then the
“abortion” issue looms large, especially given that such “infertility
treatments” are still rather experimental (not sure what will happen,
either to the embryo or later fetus or the woman). “Prolife” no longer
has the luxury of considering and protecting only sexually reproduced
human beings /in vivo/.
For starters, extensive human cloning, and other forms of human genetic
engineering -- *all of which can asexually reproduce new living
single-cell human organisms (human beings)* -- are already being done in
IVF clinics, for both "research" and for "reproductive" purposes. One
of the most common IVF techniques is called “twinning” – and twinning is
one of many different kinds of /cloning techniques/. The procedure
mimics the kind of identical twinning that takes place naturally inside
the fallopian tube of a women, resulting in the asexually reproduction
of an identical twin, triplet, etc. This long-used “infertility
treatment” involves implanting the resulting twins/triplets into a
woman’s uterus, and bringing them to birth. Along with using the
“twinning” cloning technique, IVF centers also use several other human
cloning techniques to asexually reproduce new living human embryos which
are likewise implanted and brought to birth.
Below are just two published research studies documenting (1) the
various kinds of human cloning techniques available to IVF "clinics",
and (2) an example of how it is already being done:
#1. Note that various cloning techniques have already been developed in
animal work for over 25 years, and are applicable to cloning human
beings. Here *several human cloning techniques* are mentioned,
including "hemicloning", "nuclear transfer", and "embryo splitting"
(twinning – also called “blastomere separation, blastocyst splitting,
embryo multiplication, etc.):
*New techniques on embryo manipulation**.* Escriba MJ, Valbuena D,
Remohi J, Pellicer A, Simon C. (Spain)
For many years, experience has been accumulated on embryo and gamete
manipulation in livestock animals. *The present work is a review of
these techniques and their possible application in human embryology** in
specific cases*. It is possible to *manipulate gametes* at different
levels, producing *paternal or maternal haploid embryos (hemicloning)*,
using different techniques including *nuclear transfer.* At the
embryonic stage, considering practical, ethical and legal issues,
*techniques will be reviewed that include cloning and embryo splitting
at the cleavage stage, morula, or blastocyst stage*. [PubMed

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12062830
#2. Note that *human cloning can be used for both "research" and for
"reproductive" purposes, e.g., for "infertility treatments"**.* In the
study below, the human *oocytes** *from *infertility patients in private
IVF clinics* were *cloned** *using "nuclear transfer". Since the
transfer was not done using a "somatic" cell, it is not properly defined
as "somatic cell nuclear transfer" (SCNT), but rather as "germ line cell
nuclear transfer" (GLCNT). Both somatic cells and germ line cells
(e.g., oocytes) are *diploid*, therefore nuclear transfer (cloning) can
be accomplished using either type of cell. The "product" is referred to
below as a "reconstructed oocyte", and it is "activated". That means
that upon activation *a new genetically unique living human being -- a
single-cell human embryo -- has been reproduced by means of human
cloning using the GLCNT technique**.* The term "reconstructed oocyte"
is a euphemism, or "pre-embryo substitute" for the single-cell *human
organism* formed by cloning. It is not just an "oocyte" any more. It
is a single-cell human being. I question how the *"informed consent"*
forms phrased it so that these infertility patients understood clearly
and unambiguously that their diploid oocytes had been used to asexually
reproduce their own cloned children?
Fertil Steril. 2003 Mar;79 Suppl 1:677-81
*Microfilament disruption is required for enucleation and nuclear
transfer in germinal vesicle but not metaphase II human oocytes**.**
*Tesarik J, Martinez F, Rienzi L, Ubaldi F, Iacobelli M, Mendoza C,
Greco E. (Spain)
OBJECTIVE: To evaluate the usefulness of microfilament disruption
*before enucleation and nuclear transfer in human oocytes at different
stages of maturation*. DESIGN: Prospective experimental study. SETTING:
*Private clinics. PATIENT(S): Infertile couples undergoing assisted
reproduction attempts.* INTERVENTION(S): Oocyte enucleation and nuclear
transfer, *activation of reconstructed oocytes.* CONCLUSION(S):
Microfilament disruption before enucleation is required for germinal
vesicle oocytes but not for metaphase II oocytes. [PubMed Reference:
PMID: 12620476]
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12620476
Indeed infertility researchers are eager to use any and all cloning
techniques for infertility “therapies”, and thus they attempt to limit
the damage of any pending cloning legislation by narrowing the
definition of “cloning” to just SCNT. As admitted recently by Dr. Jamie
Grifo, a leading infertility researcher at New York University:
“Infertility researchers take pains to define cloning in the narrowest
terms, as a process that would use the nucleus from a single mature cell
and place it in a woman's egg from which the nucleus had been removed -
then jolting that hybrid cell to life with electricity. No sperm need
be involved, so the baby's genetic material would all come from just one
person. While many infertility specialists recoil at the prospect of
such ‘solo’ cloning, there are critical aspects of the process that
could help infertile couples. A number of infertility programs across
the country are working on treatments that might be called ‘near-cloning’.
[Doctor Jamie Grifo, a leading infertility researcher at New York
University, as quoted in Stephen Smith, “Cloning bans could have impact
on infertility treatments”, Jan. 9, 1998, at
http://www.geometry.net/detail/basic_i/infertility_family_science_page_no_3.html.]
Thus as Weissman redefines SCNT as just “stem cell research”, many
infertility researchers /redefine all cloning techniques as just
“infertility treatments”/ involving “near-cloning”! We are /clearly/
talking about /“reproductive cloning”/ here, not just “infertility
treatments”. Hello?

*The future of fertility*
100-year-old women giving birth; IVF cycles available for £50; gestation
in artificial wombs... it will all be possible in the next 30 years, say
the world's leading fertility experts
By Jeremy Laurance
Thursday, 17 July 2008
Thirty years ago the birth of Louise Brown, the world's first test-tube
baby, marked a genuine medical breakthrough – one of the few that
deserves the title. Until then, the limited treatments on offer –
surgery and hormone therapy – could help only some of the millions of
infertile couples devastated by the discovery that they were unable to
create a family.
On 25 July 1978 they learnt they had another option that could deliver a
baby – and a future. Early fears about the safety and morality of the
procedure were swept aside in the rush to take advantage of it. Today,
some four million babies have been born by IVF worldwide. In Britain it
is estimated that every primary school has at least one IVF child.
Yet as quickly as it has solved problems, the new science of fertility
has created them. No area of medicine has seen more spectacular
advances, but no area has thrown up more ethical conundrums.
At the time of Louise Brown's birth, doctors were able to treat barely
half of the infertile couples – one in seven of the population – who
came to them for help. Surgery for blocked fallopian tubes and hormone
treatment to stimulate egg production were the only available treatments
for women. There was nothing available for men.
Today, in a special report published by the journal Nature, scientists
make some extraordinary predictions about the future of fertility
treatment. They forecast an end to infertility with the potential for
any person of any age from one to 100 to have children. In place of a
normal pregnancy, gestation might take place in an artificial womb, with
embryos selected and genetically manipulated to ensure they were free of
disease.
Low-cost IVF might be made available at £50 a cycle, putting it in reach
of some parts of the developing world. Cloned babies, though banned in
this country and many others, are likely to become a reality, scientists
say.
Thirty years ago these claims would have been treated as science
fiction. Today they seem entirely realistic, beside the advances we have
already seen. Who would have predicted in 1978 that male infertility
would be successfully treated by injecting individual sperm directly
into the egg? The technique, known as intra cytoplasmic sperm injection
(ICSI), first introduced in 1992, is now used in more than half of all
IVF treatments in the UK.
Who would have predicted that embryos would be selected, by sex or by
genetic markers for almost 200 diseases using the technique of
pre-implantation diagnosis, so that only healthy ones were replaced in
the womb?
Today we have saviour siblings (babies created to provide a sick older
sibling with matching tissue) and animal-human hybrids (created by
placing human cell nuclei into the eggs of cows or rabbits to create
embryos that are 99 per cent human and are used for research up to 14
days – because of the shortage of human eggs).
The most exciting area is stem-cell research using embryos – and
ordinary adult skin cells treated to behave like embryonic stem cells,
called induced pluripotent stem cells (iPS) – from which it is hoped new
tissue can be grown for the treatment of conditions including
Alzheimer's , Parkinson's and similar conditions.
This is the new scientific frontier on which, 30 years on from Louise
Brown's birth, researchers now stand. Work on embryos which was
exclusively focused on developing new treatments for infertility has now
expanded to include the search for cures for disease. With an updated
Bill due to be passed into law later this year, which gives legal
sanction to these techniques, the stage is set for further advance – and
further controversy.
(See www.nature.com)
*Looking ahead: how the news may be made*
*100-year-old gives birth*
Davor Solter, a developmental biologist at the Institute of Medical
Biology in Singapore
I think IVF has gone about as far as it can. Next I expect that germ
cells – sperm and eggs – will be derived from induced pluripotent stem
(iPS) cells [cells that have the potential to develop into any of the
body's cell types]. It will be possible to make iPS cells from skin
cells, to make germ cells from these, and then combine them to make
human embryos. It means every person, regardless of age, will be able to
have children: newborn children could have children and 100-year-olds
could have children. It could easily happen in the next 30 years. I have
no idea if the technique will be used, but it means you could have
millions of gametes that could be combined at will. I have no idea what
kind of moral value or rights we would give to those embryos. We'll
probably go through the same agonising we did with IVF. It could be
terrible to begin with, but then it'll become a fact of life. Maybe 20
to 30 years from now we'll read that someone made 20,000 embryos and
studied their development, and we'll decide it's OK.
*Cost of IVF falls to £50*
Alan Trounson, an IVF pioneer and director of the California Institute
for Regenerative Medicine in San Francisco
IVF was a gigantic step. We didn't realise it at the time; people didn't
think it would work that well. We never envisaged that it would expand
so dramatically around the world. Ethics keeps moving. What was once
seen as dangerous goes on to be seen as within the confines of
acceptable risk. Probably the major development in the field will come
from something we've never thought about. I think there will be a
further expansion of low-cost IVF, especially for women in developing
countries who experience social discrimination with infertility. If you
remove all the expensive stuff and use low-cost drugs (such as
clomiphene) and remove just one or two eggs, and only transfer one
embryo, it can be done for less than US$100 (£50).
*First cloned baby born*
Miodrag Stojkovic, stem-cell biologist at the Prince Philip Centre of
Investigation in Valencia, Spain
Will we see a cloned baby? It could happen any day because of a lack of
regulation [in some countries]. People are already trying to do
reproductive cloning. The only problem is getting hold of enough viable
human oocytes [eggs]. If we can make human oocytes from stem cells, it
might be easier. There is no medical need to clone a human. The future
is not about reproductive cloning, that's a very, very detrimental
technique.
*The artificial womb*
Scott Gelfand, director of the Ethics Centre at Oklahoma State
University in Stillwater
There is some research aiming to increase embryo survival. There are
also people who are working on the other end – at the moment babies can
only survive from about 22 weeks. Someone could join these two advances
together and we could have complete ectogenesis [in which the foetus
develops outside the body in an artificial uterus]. I find it
interesting – and scary. Even in terms of insurance: if it became
economically competitive with other forms of gestation, insurers might
compel a person to use it to avoid premature birth or foetal alcohol
syndrome. It's something that really needs to be talked about. Will it
happen? Dolly was a complete surprise to everybody...
*Parents can choose favourite embryo*
Susannah Baruch, director of reproductive genetics at the Genetics and
Public Policy Centre at Johns Hopkins University in Washington DC
There's speculation that people will have designer babies, but I don't
think the data is there to support that. No single gene predicts
blondness or thinness or height or whatever the 'perfect baby' looks
like. You might find genetic contributors, but there are so many
environmental factors too. More likely is that you'll have a set of
embryos and you'll know every single thing about every gene in every
embryo. For example, one embryo will have three genes associated with
tallness, two for weakness, three for poor vision and some for disease;
and the second embryo will have some other set. None of us is a perfect
specimen and none of our embryos will be, either. I think you'll end up
with a lot of information but it's less obvious how useful that
information will be and how many parents will want it. Will people
choose IVF to get that genetic option? The old-fashioned way is cheaper
and more fun and that won't change in 30 years.
*Infertility is history*
Zev Rosenwaks, director of the Centre for Reproductive Medicine and
Infertility in New York
I see the technology going towards possible eradication of infertility
altogether. With nuclear-transfer technology or cell modification, I
think we'll be able to generate sperm and eggs for anybody.
