What requirements have to be met for stem cell research to be ethical?

Among others, three particular requirements stand out:

  • Human beings cannot be killed for the research.
  • Human beings cannot be created for the research.
  • Human beings cannot be put at unnecessary risk for the research.


Violating any one of these conditions would be immoral and would fail to respect the dignity and rights of other human beings.

The first condition means that embryos cannot be killed to get their stem cells.

The second condition means that test tube babies or cloned embryos cannot be created for use in research.

The third condition means that the techniques used to collect stem cells must be safe. For example, if amniotic fluid were being collected, it would have to be done in a way that does not endanger the child.
