Mr. Speaker, I am pleased to participate in the debate on this issue.
As a member of the Standing Committee on Health, I identify with the comments of the hon. member from Winnipeg who just spoke. Members of the committee wrestled with many of the issues surrounding human reproductive technology and came up with the proposals for the draft legislation which has come back in the form of Bill C-56.
Bill C-56 states it may be cited as the assisted human reproduction act. I would like to state for the record that I believe we need much more research on the causes of infertility, particularly in the western world on delayed child bearing. We need more scrutiny on the various practices that defer pregnancy including the birth control pill; the use of abortion and the effect it has on fertility; the accumulation of pesticides in the environment and the effect it may have on human reproduction; and recently, concerns about estrogens accumulating in the water supply which are affecting human fertility.
A lot more research is needed on what is actually causing this epidemic of infertility. Rather than trying to find other ways to produce babies, we should be looking at how we can accommodate successful human fertility in a natural way.
Looking at the bill, the opposition has been calling for legislation since 1993 when the royal commission on new reproductive technologies reported. The government introduced Bill C-47 eventually in June 1996 and it died on the order paper.
This subject has been debated for a long time. In this the 37th parliament the Standing Committee on Health received draft legislation on May 3, 2001, a little more than a year ago. We spent months deliberating and hearing from witnesses from all aspects of Canadian society who are concerned about the complex and varied issues associated with the bill. Finally the committee submitted its report in December to the minister. It is one year later and the bill has finally come to the House for consideration. It has been a long time coming.
There are many controversial aspects and complex issues related to the bill. Probably the most significant one is the issue of stem cell research. To enter into that subject, it was stressed at committee that we need to think of ourselves as cellular beings. An adult human being is some 80 trillion to 100 trillion cells; we are cellular beings.
We are talking about embryonic stem cells versus adult stem cells. We hear in discussions that embryonic stem cells are better because they can produce the entire array of tissue found in an adult human being, which is true. The early cells in an embryo are on their way to producing an 80 trillion to 100 trillion cell adult which will take some 20 years to accomplish. The embryonic cells can produce a whole human being; that is their destiny in the ordinary sense.
Recent research has found what early researchers used to suggest, that adult cells are no longer able to do that. However in the last year and a half we have seen tremendous breakthroughs in adult stem cell research.
It should not have been such a surprise to us. The blueprint for each one of us, including all of the 200 cell types that we have in our body, is found in each and every cell of the human body, except for the red blood cells which do not have a nucleus. Each of us has in each of our 80 trillion to 100 trillion cells a complete set of chromosomes with a complete blueprint to reproduce a whole human being.
Therefore the dialogue saying that the embryonic cells are better for this reason simply does not hold up with the current research. We are finding tremendous breakthroughs some of which have been cited already today.
We heard from researchers in committee, and even in the months since we concluded our report there has been further research reporting results with Parkinson's disease using adult stem cells. Also with multiple sclerosis, adult stem cells from the donor's body were introduced back into the same body with tremendous results.
From what we heard in the standing committee and in the past year, there have been tremendous gains in adult stem cell research in humans. We heard that after many years of embryo stem cell research with animal models the results have not provided the expected advances. Therefore, it was the conclusion of the standing committee to encourage research funding in the area of adult stem cells.
There are many problems with trying to introduce embryonic cells into another human being not the least of which is each one of our cells has a blueprint, our own genetic marker. An intact immune system checks licence plates. The immune system will reject foreign cells. If embryonic cells are used to produce a new cell source for a human being to try to solve a health problem those cells will be subject to rejection by the immune system of the receiving body unless the patient takes anti-rejection drugs for the rest of his or her life. That is a very significant problem in trying to use embryonic stem cells in another human being. It is a problem that is avoided entirely by the use of autologous cells, or cells from one's own body.
To quote a couple of other advances, recently University of Minnesota Stem Cell Institute researchers showed that adult bone marrow stem cells can become blood vessels. Duke University Medical Center researchers turned adult stem cells from knee fat into cartilage, bone and fat cells. When the research of Dr. Freda Miller from our own McGill University was announced just a few months ago, the newspaper article said that the researchers had found gold with skin cells able to turn into neurons or muscle cells.
We should have known there were stem cells found in bone marrow because bone marrow regenerates itself. The average human being is replacing 25% of his or her blood every month. Skin cells replace themselves regularly. Therefore stem cells are found. Also we are finding that skin cells not only produce skin but they can be coaxed into forming other tissues, as Dr. Miller found, such as neurons or muscle cells.
If adult cells have the promise to produce tissue, why are researchers reluctant to go there? I posed that question to Dr. Alan Bernstein, the head of the CIHR, when he was at committee and I pose the question again to my colleagues in the House. If we can produce cells from our own bodies that would replace tissue, avoiding the need for anti-rejection drugs for life, if we could take stem cells from our own bodies, grow them in a Petri dish and reintroduce them to our bodies to repair damaged tissue, would that not in fact be superior? That is autologous.
