Stem Cell Ethics
The ethical standards of stem cells really come down to a few simple questions:
Human vs. Animal?
Mine vs Yours?
Embryo or not?
It is always best for stem cells to come from another human, but stem cells from animals can and have been used on Winston Churchill, John F. Kennedy and many Royal Families of European and Asian origin; however we have graduated to using cells from our own species.
It is always more ethical to use human stem cells that come from oneself, but certain stem cells from others are ethically used to reverse cancer, comma and stroke.
Is it always not ethical to use an embryonic derived stem cell.
Stem cells from amniotic fluid, human blood, fat and placenta are ethical sources of stem cells that meet ethical standards that are focused on reduced suffering with no harm to the source or the patient.
