cells were originally dubbed "miracle cells" by researchers, because of their potential to treat or cure many human diseases (for more on stem

And it caught many scientists off guard, who were initially surprised and encouraged to learn that so many stem
cell lines would be available shortly (part of their early encouragement was due to the fact that most had expected Bush to ban federal funding outright).
I am excited about the potential of stem

cells frighten me.
The President said that he would allow federal funding--but only on approximately 60 stem
