No one was more surprised than me,

When we talk about stem cells, we are actually talking about a complicated series of things, including adult stem cells which are largely cells devoted to replacing individual tissues like blood elements or liver or even the brain.

I think we can allow the therapeutic uses of nuclear transplant technology, which we call cloning, without running the danger of actually having live human beings born.

The argument has been made in Congress that it is slippery slope if you allow therapeutic, what people people are calling therapeutic cloning, then you will get reproductive cloning.

When are we going to say cancer is cured? I'm not sure when that will happen, if that will happen because cancer is a very slippery disease and it involves a vast number of cells in the body and those cells are continually mutating.

In the last few years these efforts have been remarkably successful. It has been possible to identify both genes and the proteins involved in cancer induction.
