People have used the argument-not a scientific argument but a political argument-that we don't need to do human embryonic stem cell research because, after all, mature or adult stem cells will do everything. Doug's paper says that's not exactly correct.
The thing that people with diabetes who have to take insulin hate the most are shots. So anything that can replace shots patients are going to be very pleased to have.
It's not going to be an overnight sensation. My concern is that people will assume they are now free of insulin shots.
We want to make sure people understand that this does not equal getting rid of all their insulin shots.
