• but: alternatives, e.g. adult stem cell research
    • because: resources could be used in a better way
    • but: embryonic stem cells have a higher power
    • because: alternatives are more promising
      • because: adult stem cell research has produced therapies
        • because: no spectacular result so far
        • but: adult stem cell studies have a much longer history
    • but: embryonic stem cells are more superior
      • because: easier to be isolated and preserved
        • because: difference in proportion
      • because: can treat wider range of diseases
        • because: higher malleability
      • because: more useful for nervous system therapies
      • but: may be rejected by the immune system
      • because: more capable in offering immediate treatment
        • because: easier to generate large numbers of cells
          • because: embryonic stem cells divide more rapidly
      • because: more effective in treating genetic disorders
      • because: DNA abnormalities
  • because: embryo less valuable than child or adult
    • because: embryos cannot exist outside the womb
    • but: embryo is a life, just as much as a child or adult
      • but: embryo no brain activity til 54 days
Embryonic stem cell research should be supported and funded by the government
  • because: benefits of stem cell research outweigh the cost
    • because: existing disease cost more than destroying embryos
    • because: embryonic stem cells useful to treat diseases
  • but: violates the sanctity of life
    • but: unused embryos destructed anyway
    • but: alleviation of suffering, treatment of diseases
    • because: constitutes murder
      • because: necessitates destruction of embryo
        • because: new techniques: no destruction of embryo
          • because: transferring somatic cell nucleus
      • because: (co) an embryo is a life
        • but: an embryo is not fully human
          • because: not able to think and feel
          • because: incapable of existing outside the womb
        • because: an embryo will develop into adult
