In Britain, like most of the developed world, stem-cell research is regarded as a great opportunity. America will be left behind if it doesn't change policy.

Stem cell research is the key to developing cures for degenerative conditions like Parkinson's and motor neuron disease from which I and many others suffer. The fact that the cells may come from embryos is not an objection, because the embryos are going to die anyway.

There are many alternatives to embryonic stem cell research, alternatives with great potential. We need to support these and oppose creating life for the sole purpose of destroying it.

I wholeheartedly support umbilical stem cell research, but also support embryonic stem cell research.

Under current federal policy on human embryonic stem cell research, only those stem cell lines derived before August 9, 2001 are eligible for federally funded research.

Embryonic stem cell research will prolong life, improve life and give hope for life to millions of people.
