 The Pros and Cons of Stem Cell Research


                    Pro: Brendan Meehan and
                        Joyce Lee

What Are Stem Cells?

   Primal Cells
    –   Can differentiate into all
        specialized cell types
   Stem cell research
    –   Study problems that
        occur in transformation
    –   Dr. James Thompson
Stem Cell Research Should Be
Continued

 Can cure a large variety of
  diseases
 Grow tissues to test drugs
 Other nations are moving
  forward with stem cell research
New Cures for Diseases

   Stem cells can grow into any type of cell
    –   Brain cells, veins, bones, entire organs
   Replacements can be customized with the
    patients’ DNA
   Cure heart diseases
    –   Largest killer in the U.S.
Grow Tissues to Test Drugs

   No human subjects
    needed
    –   Grow genetically uniform
        tissue in labs
   Take DNA from
    patients with genetic
    diseases to study
    genetic diseases

Stem Cell Research Should Not be
Continued

 Destroying Embryos
 Government Has Banned Stem
  Cell research
 Dangerous Animal Testing
Destroying Embryo’s

   Still Human Beings
   State cannot live outside womb or without
    medical help
    –   Leads to saying that people on life support are not
        human either
   State lack sentience
    –   Can then state people with Alzheimer's or
        debilitating disease’s are not human
Destroying Embryo’s (cont.)

   Federal law stating that it’s a crime to kill or
    injure a bald eagle or their eggs
   Willing to kill stem cells
   Makes it look like we are more coherent
    when it comes to eagles than when with
    humans
Government Restrictions

   Bush- who is against stem
    cell research, had banned
    any testing on them
   Forced to find alternatives
    –   Amniotic fluids
    –   Human bone marrow


   Have been testing but
    useless effort; waste of
    time and money
Dangerous Animal Testing

 Putting human eggs and sperm in
  animals
   – Giving animals human brains
     and organs
   – Dangerous if animals mate
 Animal testing is ineffective and
  inaccurate
Destroys Embryos But…

   Serves a purpose
   Embryos aren’t really
    human
    –   invisible to the naked
        eye
    –   has no nervous system
    –   no identifying features
    –   lack sentience
          Government Restrictions But…

Dangerous Animal Testing But…

   New ethical guidelines from the Academy
    –   Chimeric animals should not mate
    –   Human embryonic stem cells should not be
        injected into nonhuman primates
    –   Human embryos should not be grown in a lab
        for more than 14 days
   Animal testing makes it safer for humans

PRO                     CON
 New cures              Destroys
 Test drugs              embryos
                  VS.
 Compete with           Government
  other nations           has banned
                          stem cell
                          research
                         Risky animal

To Be Honest…

   We all support stem cell research
    – Medicinal and scientific benefits
    – Further research could eliminate
      dangers
    – Many unwanted embryos in
      fertility clinics
Stem Cell Research…


    It Could be the Future
              Or
     It Could be the Past.
