Stem Cells Quotes
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.
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.
Stem cells have the potential to be used to treat and better understand some of the world's most deadly and disabling diseases.
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.
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.
The average person doesn't understand what a stem cell is. There's a lack of health literacy in our nation. So the public can't really get into this dialogue because they don't understand the complexity of stem cells, not the faith-based approach, not the ideological or political, but the science behind stem cells.
Stem cells are being used for anti-aging, and the University of Miami is doing a study about that to prove that it is true. They are looking at me, and my markers have shown exactly that I have been actually reversing my aging and getting younger. I am taking perhaps more stem-cell treatment than anybody else in the world.
Through their work with fetal tissue, researchers hope to find ways to harness embryonic stem cells which have the ability to become any type of human cell and could provide new treatments for many illnesses.
Mr. Speaker, the scientific evidence is overwhelming that embryonic stem cells have great potential to regenerate specific types of human tissues, offering hope for millions of Americans suffering from debilitating diseases.
Throughout our lifetimes, we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.
The Stem Cell Research Enhancement Act would expand research on embryonic stem cells by increasing the number of lines stem cells that would be eligible for federally funded research.
There are no bona fide treatments available for embryonic stem cells. There is nothing in the laboratory, and there is certainly nothing in the clinics available to patients.
I was working with stem cells as part of a NASA programme. We realised that the science of stem-cell proliferation was also fundamental to cancer cells when cancer enters the phase of metastasis.
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.
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.
Adult stem cells are also problematic, as they are difficult to identify, purify and grow, and simply may not exist for certain diseased tissues that need to be replaced.
The first misconception is that embryonic stem cell research is not legal. The fact is, embryonic stem cell research is completely legal. Research on embryonic stem cells has taken place for years.
Stem cells are probably going to be extremely useful.
We know that in 2001 it was believed 78 stem cell lines existed. But now we know there are only 22 that are viable, and they have been contaminated with mouse stem cells.
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.
Today, it is research with human embryonic stem cells and attempts to prepare cloned stem cells for research and medical therapies that are being disavowed as being ethically unacceptable.
If the government regulates against use of drones or stem cells or artificial intelligence, all that means is that the work and the research leave the borders of that country and go someplace else.
Adult stem cells tend not to form tumors.
The most dangerous cancer cells are actually the ones that are more like stem cells, which have this ability to produce themselves over and over again. More and more cancer biologists say stem-cell-like cells in cancers are the most dangerous.
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.
