Stem cells are probably going to be extremely useful.

In fact when you combine stem cell technology with the technology known as tissue engineering you can actually grow up entire organs, so as you suggest that sometime in the future you get in an auto accident and lose your kidney, we'd simply take a few skin cells and grow you up a new kidney. In fact this has already been done.

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.

Without a doubt, stem cell research will lead to the dramatic improvement in the human condition and will benefit millions of people.

We need stem-cell research, no question about it. It is absolutely crucial for moving our medical science forward. We are trying to harness an untapped source of energy that can provide cures and possibly even prevent disease and suffering.

I think we're rapidly approaching the day where medical science can keep people alive in hospitals, hooked up to tubes and things, far beyond when any kind of quality of life is left at all.

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 art of phlebotomy originated with bloodletting in 1400 B.C., and the modern clinical lab emerged in the 1960s - and it has not fundamentally evolved since then. You go in, sit down, they put a tourniquet on your arm, stick you with a needle, take these tubes and tubes of blood.

The benefits of biomedical progress are obvious, clear, and powerful. The hazards are much less well appreciated.

I almost had to have my leg amputated because of an infection.
