...nearly every poll, voters say they disagree with the President's veto by about a 2-to-1 ratio. Almost half of those surveyed in an NBC/Wall Street Journal poll last week said that either they or someone in their family suffers from one of the conditions--cancer, Parkinson's disease, juvenile diabetes, Alzheimer's disease, spinal-cord injuries or heart disease--for which stem-cell research is believed to hold the greatest promise. "There are a lot of things we do here [in Washington] that don't touch people directly. This one does," says Congressman Rahm Emanuel, head...
...what is the correct dose of hope when the diseases are dreadful and the prospects of cure distant? Last month, when President George W. Bush vetoed the bill that would have expanded funding for human embryonic-stem-cell (ESC) research, doctors got calls from patients with Parkinson's disease saying they weren't sure they could hang on for another year or two. The doctors could only reply that in the best-case scenario, cures are at least a decade away, that hope is no substitute for evidence, that stem-cell science is still in its infancy...
Even if scientists discover an ideal source of healthy cell lines, there is still much to learn about how to coax them into turning into the desired kind of tissue. Parkinson's patients suffering from tremors caused by damaged nerves could benefit from replacement neurons, while diabetics who can't produce insulin could control their blood sugar with new pancreatic islet cells. But so far, no human ESCs have been differentiated reliably enough that they could be safely transplanted into people, although animal studies with human cells are under way. Not surprisingly, the groups closest to human trials...
...body. They have the ability to self-renew, which means that they are theoretically immortal and can continue to divide forever if provided with enough nutrients. Because they are so plastic, they hold enormous promise as the basis for new treatments and even cures for disorders ranging from Parkinson's and heart disease to diabetes and even spinal-cord injury...
