With all this talk over whether it is right to federally fund new lines of human stem cells for study research, consider this.
Scientists have recently corrected the broken hearts of rats by the use of implanted human stem cells.
I don't know why they can't use rat stem cells for this. It would seem from the pressure that is placed on congress to fund more research that the human variety is rare and costly.
So, why are they injecting human cells into rats?
Don't get me wrong, I think this is important research, but I think that there should be a premium placed on human life.
