Using adult stem cells drawn from bone marrow and umbilical cord blood system cells, scientists have discovered new treatments for scores of diseases and conditions such as Parkinson's disease, juvenile diabetes, and spinal cord injuries.
But cord blood also holds the great potential of producing pleural potential cells that could cure many other diseases such as juvenile diabetes, a disease that I live with every day.
Adult stem cells have shown great potential and have effectively helped patients. Another alternative is cord-blood stem cells. These are a neglected resource that could be used to treat a diverse body of people.
Scientists have stated that embryonic stem cells provide the best opportunity for devising unique treatments of these serious diseases since, unlike adult stem cells, they may be induced to develop into any type of cell.
Alzheimer's, Parkinson's, brain and spinal cord disorders, diabetes, cancer, at least 58 diseases could potentially be cured through stem cell research, diseases that touch every family in America and in the world.
Cord blood stem cell units have been shown to be a suitable alternative to adult bone marrow for the treatment of many diseases, including sickle cell anemia.
There was a disc and two bone spurs pressing on my spinal cord. If anyone's had spinal cord problems or disc injuries in their neck, they'd understand what I went through.
When we talk about stem cells, we are actually talking about a complicated series of things, including adult stem cells which are largely cells devoted to replacing individual tissues like blood elements or liver or even the brain.
Well, there are two kinds of stem cells: adult stem cells, which you can get from any part of a grown body, and embryonic stem cells. These are the inner- core of days-old embryos that can develop into any kind of cell.
My goals over the decade include to develop new drugs to treat intractable diseases by using iPS cell technology and to conduct clinical trials using it on a few patients with Parkinson's diseases, diabetes or blood diseases.
Both in Britain and America, huge publicity has been given to stem cells, particularly embryonic stem cells, and the potential they offer. Of course, the study of stem cells is one of the most exciting areas in biology, but I think it is unlikely that embryonic stem cells are likely to be useful in healthcare for a long time.
One of the first papers I wrote at the University of Wisconsin, in 1977, was on stem cells. I realized that if I changed the environment that these cells were in, I could turn the cells into bone, and if I changed the environment a bit more, they would form fat cells.
One can envisage taking cells from a patient with sickle-cell anaemia or an inherited blood disorder and using the Cas9 system to fix the underlying genetic cause of the disease by putting those cells back into the patient and allowing them to make copies of themselves to support the patient's blood.
Today, my brother and I share almost identical DNA, the result of a successful bone marrow transplant I had last April using his healthy stem cells. But Adam and I couldn't be more different.
The private sector can go forward, if it must, with destruction of embryos for questionable and ethically challenged science. But spend the people's money on proven blood cord, bone marrow, germ cell, and adult cell research.
So why in the world would anyone support the unethical, failed use of embryonic stem cells instead of the ethical, successful use of adult stem cells? Because they do not know the difference.
Stem cell research is the key to developing cures for degenerative conditions like Parkinson's and motor neuron disease from which I and many others suffer. The fact that the cells may come from embryos is not an objection, because the embryos are going to die anyway.
