I'm very grateful that President Obama has lifted the restrictions on federal funding for embryonic stem cell research.

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

Embryonic stem cell research has the potential to alleviate so much suffering. Surely, by working together we can harness its life-giving potential.

The refusal to acknowledge the scientific value of embryonic stem cell research is one more tragic misstep.

You cannot be against embryonic stem cell research and be intellectually and therefore morally consistent, if you're not also against in vitro fertilization.

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