The debate on stem cell research is centering on harvesting stem cells from human embryo's. It turns out the most promising research is coming from adult stem cells. Brazilian researchers have taken stem cells from patients' bone marrow and injected into their hearts to repair damage patients on heart transplant lists. Four of the five patients tested were successful enough to be removed from the lists.
Maggie Gallagher has a great view on this. Research ought to be going to the most promising area of research, not the most controversial.
