WebMD notes that public support for stem cell research is rising (and there's more on the same theme at the Fight Aging! blog). "When asked for their initial views on medical research using human embryos, a survey conducted in 2001 showed 48% of Americans supported it and 43% were opposed. This survey shows that margin has grown to 60% and 26%. When the potential benefits of stem cell research were explained in a separate question, overall support rose to 72% with 23% opposed." Research advocates have been working hard to educate people over the past few years. I think that increased public support stems from a greater understanding of what is actually involved in this research and the nature of the potential benefits.
