No, his definition includes KILLING one human to use his or her body parts on another.
We have no idea what they could be used for until we try.
But scientists are learning what they CAN'T be used for and that, my friend, is the point.
An unborn fetus, whether through abortion or miscarriage provides those cells and I think we should use them.
First of all, there have been no restrictions on private funding of embryonic stem cell research, only federal funding. Yet private donors don't seem to be rushing to give their money away - why do you think that is? Hint - see above statement about what scientists are learning.
Secondly, think about this - how will we ever reduce the number of abortions in this country if the organizations providing them have the carrot of additional federal funding for collecting tissue in the name of scientific research?
""But scientists are learning what they CAN'T be used for and that, my friend, is the point.""
And, any such information should first be sought in experiments that are carried out on animal models until techniques are in place that do not require the killing of humans and which are acceptably safe for all the human research subjects.
