Researchers and biotech executives foresee the day when the effects of many catastrophic diseases can be reversed. The damaged brains of Alzheimer's disease patients may be restored. Severed spinal cords may be rejoined. Damaged organs may be rebuilt. Stem cells provide hope that this dream will become a reality.
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.
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.
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.
The good news is we are seeing an incredible surge in non-animal technologies in laboratories. With researchers using stem cells, visually impaired people may one day have new corneas and lenses grown from their own cells. That is likely to be a more effective and cheaper approach than using animals.
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.
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.
I may not be funny. I may not be a singer. I may not be a damn seamstress. I may have diabetes. I may have really bad vision. I may have one leg. I may not know how to read. I may not know who the vice president is. I may technically be an alien of the state. I may have a Zune. I may not know Excel. I may be two 9-year-olds in a trench coat. I may not have full control of my bowels. I may drive a '94 Honda Civic. I may not “get” cameras. I may dye my hair with Hydrogen Peroxide. I may be afraid of trees. I may be on fire right now. But I'm a fierce queen.
The post-war loss of Churchill may have damaged the Western world with the same impact as the post-civil war world was damaged by the loss of Lincoln.
Now science has presented us with a hope called stem cell research, which may provide our scientists with many answers that have for so long been beyond our grasp.
There's already a lot of active research going on using the Crispr technology to fix diseases like Duchenne muscular dystrophy or cystic fibrosis or Huntington's disease. They're all diseases that have known genetic causes, and we now have the technology that can repair those mutations to provide, we hope, patients with a normal life.
So to recap: we may or may not be going to war with Iraq because Saddam may or may not have weapons of mass destruction, which he may or may not use, or pass to other terrorists groups with whom he may or may not have links.
IPS cells can become a powerful tool to develop new drugs to cure intractable diseases because they can be made from patients' somatic 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.
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.
The issue of torture, connected to American soldiers, is not somewhere most people want to linger. We may not want to confront this issue so much in the U.S. because of how we want to think about our veterans. There's the sense that we want to think of our veterans as - if they're damaged, damaged by something glamorous, like a firefight.
Going after a dream has a price. It may mean abandoning our habits, it may make us go through hardships, or it may lead us to disappointment, et cetera. But however costly it may be, it is never as high as the price paid by people who didn't live. Because one day they will look back and hear their own heart say: 'I wasted my life.'
