Donating Eggs for Embryonic Research

By Mary Hamilton

Much has been made of the controversy regarding embryonic stem cells. However, there is one aspect of this controversy that is always ignored by the media- the role of women as egg donors for these embryonic stem cells. More than 1% of egg donors (the source of human Embryonic Stem Cells) suffer "serious long-term consequences"

Mary Hamilton, a zoologist and adult stem cell advocate explained the dangers of obtaining eggs for human Embryonic Stem Cell research when she testified before the Michigan House of Representatives. We present to you the full transcript of her testimony along with citations that verify her testimony:

My name is Mary Hamilton

Concerned by technology’s growing exploitation of women, this year’s International Women’s Day launched a collaboration between pro-choice and pro-life women called Hands off Our Ovaries. (1)

SCIENCE Magazine recently noted that obtaining eggs for research, is a " major challenge facing human embryonic stem cell research" (2) – or hES for short. Doctors should recommend against non-medical donations since, "up to 10% of women who undergo ovarian stimulation experience severe ovarian hyperstimulation syndrome (OHSS), which can cause pain, and occasionally leads to hospitalization, renal failure, potential future infertility, and even death." (3) Yet has no "clearly established benefits to the recipient" (4). The risk "is incurred not in the actual research but in the procurement of materials for the research" (5).

Many progressive countries ban egg giving (6), yet this bill relies on putting women’s health at risk so researchers can explore a theoretical avenue that has neither exhausted animal models, nor been proven as safe or more effective than other avenues.

Divided equally, there are only 220/state clinic embryos available for research (7) and researchers don’t really want them. (8) So, this bill relies on fresh embryos from newly harvested eggs – which are available from only one segment of the population – ovulating women. (9)

Yet, 1% of donors suffer "serious long-term consequences" (10).

One percent. At best, cloning would have a 1:1 egg to clone ratio. If 1/2 the country could benefit from stem cell research, one would need 150 million eggs, from 15 million women – resulting in up to 1.5 million women with OHSS - and 150,000 previously healthy young women suffering 'serious long-term consequences'. Dr. Hwang went through thousands of eggs and obtained no clones. He coerced women to donate – and 19% of them suffered OHSS. (11) Women exploited …. thousands of eggs … wasted … when primate was unachieved. (12)

What’s more, hES accrue genetic changes over time (13), and form tumors. (14) Though rare when the donor and recipient are of different species, over 70% of mice receiving ES from mice develop tumors (15). Can human safety be assured?

Yet, many scientists claim they may be better, since they obviously can become any part of the body, yet it’s this ability that causes tumors. In reality, the scientists can’t actually use embryonic cells in a test subject. The cells must be differentiated. This bill places no gestational age limit on the created embryo, theoretically allowing experimentation through adulthood - as long it can be sustained without implantation.

This rat had a spinal injury (*) - and now can walk along a rope. Laura Dominguez was paralyzed from the chest down for two years. After treatment with her own stem cells, she can use a walker and stand … on her toes. (16)

And, without putting women's health at risk.

Embryonic stem cells have shown promise (17). But in head to head studies, adult cells (18) out perform them in: the number of axons myelinated per cell; the thickness of myelination; and post-myelination nerve signal conduction speed.

Myelin plays an important role with MS. As an autoimmune disease, a 'cure' for MS is far more complicated than simply replacing damaged nerves. This is Jennifer Molson. MS left her with no feeling from her chest to her toes. After treatment with her own stem cells, she danced on her wedding day. (19)

Without putting women's health at risk.

This is Edjuana Ross. Lupus had attacked her skin, brain, and heart (20). She is one of the 50% of lupus patients with organ failure who remain disease free 5 years after participating in a clinical study. (21) Organ repair has been noted. (22)

Without putting women's health at risk.

Crohns is another autoimmune disease that has been treated with the same technique as MS & Lupus. 80% severe Crohns patients were put remission (23) and insurance companies have begun to pay for it. (24)

Without putting women's health at risk.

Dr. Dennis Turner’s Parkinson's was in remission for 4 years.(25)

Without putting women's health at risk.

Post-natal stem cells have eliminated the need for heart transplants (26), and insulin (27) in some patients. Embryonic stem cells haven’t produced the beta cells needed for insulin, but they did produce plenty of tumors (28).

Embryonic quality stem cells have been found in placentas (29), cord blood (30), amniotic fluid (31), hair follicles (32), fat (33). A rat with a liver disorder made a full recovery three weeks after it received a dental pulp transplant. (34) Adult "Blastomere-Like Stem Cells (BLSCs)," were reported yesterday. (35)

All recoverable without putting women's health at risk.

The NIH funded 20x the ES projects as cord blood stem cell projects (36). The U.S. has few restrictions and provides more money on hES than most countries combined. (37) … yet the results are not there.

A former NIH Director stated, "Ordinary people care about the destinations of science - the answers, the miracles, the cures. But a scientist cares most deeply about the journey itself." (38) So, they accept the risk to women’s health as statistically insignificant, because "basic research is just as deserving of support as therapeutic trials, but it's a harder sell" (39)

Today, you’ll hear many promises of the potential of embryonic stem cells. One promise you won’t never hear that women won’t suffer serious long-term consequences, including death, to provide research materials for studies that didn’t lead to a cure.

12 Scientists generally agree that all cloned animals are biologically flawed.

"Epigenetic Reprogramming in Mammalian Development", SCIENCE V. 293 10 Aug 2001, p. 1098 makes it clear that: Cloned animals have unpredictable problems with gene expression. Animals with the same genotype do not have the same phenotype; This problem is heightened with embryonic stem cells; This problem is neither predictable and can be triggered throughout the life of the cloned organism.

Sugaya, Kiminobu (Personal Communication, January 6, 2003). "Fundamental problem with the cloning is based on the metylation of DNA. Why our body cell has exact same genetic materials, but they become different type of cells? This is because of gene regulation by DNA metylaltion, which is a kind of memory of the cells.

If we put nuclei isolated from skin or other cells to the egg, it contains memory to become skin some extent.

So, it may not develop into the normal embryo to generate stem cells. Now we are working on the adult bone marrow stem cells to make neurons and retinal cells. It is promising and we will continue this direction."

Wilmut, Ian (Personal Communication, February 13, 2003) "data seems to say that for any given clone, any given gene, the chance of being expressed is random. Seems to be no consistency between clones."

Dr. Jean D. Peduzzi-Nelson, Ph.D. Senate Testimony, July 14, 2004. "It often stated that there is no chance of human reproductive cloning because 99.2% of cloned embryos can not survive. However, these same faulty cloned embryos are being praised as being a source of valuable stem cells that will advance the cure of genetic disorders. If these cloned human embryos are so abnormal that they almost never can survive in the womb then stem cells derived from them would also abnormal and not useful for research."

Human cloning unlikely Primate NT appears to be challenged by stricter molecular requirements for mitotic spindle assembly than in other mammals. In cattle, the somatic centrosome is transferred during NT, whereas mice rely on the oocyte's maternal centrosome. Also, NuMA and HSET are not exclusively concentrated on the meiotic spindle in mammals other than primates. With current approaches, NT to produce embryonic stem cells in nonhuman primates may prove difficult--and reproductive cloning unachievable. " (Science 11 April 2003: 297)

Hwang claims of cloning only required egg from same female cloned … as such could only clone ovulating females, procedure would not help males at all.

Op. Cit., Wilmut, Ian. Cloning not intended for therapy Dr. Wilmut wants to use them primarily "to produce neural populations from patients with motor neurone disease in order to be able to have in the lab the damaged cells for study, to test new drugs and to assess the effect of normal cells. Secondly to produce hepatocytes of different genotypes to study responses to drugs as a means of improving both safety and effectiveness of medicines." [Note, Not to "put the products back into a patient".]

13 "Embryonic Stem Cells Accrue Genetic Changes", Johns Hopkin’s Medicine (September 4, 2005),

14 "Mother of All Cells", Scientific American, July 2005, p. A7 states, "ES cells, unlike adult stem cells, cannot be used directly in therapy because they cause cancer. Indeed, one laboratory test for ES cells is to inject them into mice and analyse the teratoma (a tumour formed of foetal tissue) that arises. So any therapeutic applications will require scientists to drive the ES cells’ differentiation into particular specialised cells for transplantation into patients … rigorous screening will be required to make surenot ES cells are still present.

If establishing ES cell lines is tricky, guiding their differentiation is a scientific nightmare."
