on stem cells?
yes, on stem cells. Scientist have been doing research with embryonic stem cells using animal models, such as rats, for awhile. Using animal cells to study human diseases is the precursor to most human cell research. These studies indicate that adult stem cells show far more promise than embryonic cells to treat diseases.
There is also the larger ethical question of advancing any research that could lead to the large scale dependence on the destruction of human life. The ethical and more practical course should be to provide more funding for adult stem cell research.
