Well, we have to agree to disagree. In my mind they took undifferentiated
cells and turned them into insulin producing cells. "Only 10%?" The fact
that they coaxed these cells even into just an approximation of what they
were going for is astounding in my mind - and many researchers who
understand the intricacies and difficulties of this research much better
than I. And the fact that these cells then sustained the lives of the mice?

Not really sure of the point here. We're all going to die anyway so why
try? I am interested in wiping out the disease that is affecting my son's
life. If we are to face another disease, I'll fight that with all my might

Researchers have for many years believed that "two cures" would be
necessary. One to reinstate glucose-responsive, insulin producing cells and
one to modify the immune system. That may make it more complex, but it does
not make it unacheivable. And there is no proof that there is a "bug" that
causes a person to "contract" diabetes. We know that there is a genetic
component and an environmental component, but we do not know what the
environmental components are. It is theorized that a virus can set the
immune response in motion, but not proven. And even if this is proven, it
is very unlikely that one virus is responsible. In my previous post, I
mentioned that there is a lot of research looking into the immume response.
This research, which has made some promising headway, is aimed at
REprogramming an immune system. And this is exciting for a lot of reasons,
not just diabetes research. Prevention of this disease involves a lot more
than finding a vaccine for a bug.

You're thinking of yourself and I'm thinking of my child. I do care and so
do many, many other motivated parents. And there is a tremendous amount of
research towards preventing the disease.

Well, of course I know that :)
