in the beginning
In the Beginning…
  • All life starts with one cell
  • Cell develops into other 200 human cells
  • First of these cells called stem cells
  • Ability to change world, but at cost of potential human life
  • Should stem cell research be continued?
background
Background
  • Stem cells can divide limitlessly into all types of human cells
    • After division, cell can either remain a stem cell or become a specific cell with a particular function
  • Scientists hope to use stem cells to research the process of cellular division
    • Many sever medical conditions are result of problems with division
    • Stem cell research began with development of process to isolate and grow stem cells, first discovered by Dr. James Thompson at the University of Wisconsin
  • Much debate over continuation of stem cell research
pros of stem cell research
Pros of Stem Cell Research
  • Cures debilitating diseases
    • Have ability to grow into any type of tissue
    • Stem cells are hoped to grow new brain cells, veins, bones, entire organs
    • Can cure Parkinson’s, diabetes, cancer, etc.
  • Can be customized with DNA of patient to reduce chance of rejection
  • Can grow into heart cells
    • Can clump together and beat as one
    • When injected into pigs/mice, new cells replace the dead ones
    • Greatly reduce U.S. deaths
pros of stem cell research cont
Pros of Stem Cell Research (cont.)
  • Grow tissue to test drugs
    • Can grow tissue to test drugs on instead of human subjects
    • Cloned embryo’s from patients with genetic diseases could be used for research
  • Other nations moving ahead in stem cell research
    • U.K. had first cell bank ever
    • U.K. and Asian economies have poured money into funding for research
    • Singapore built large laboratory buildings in 2001 to jump start research
cons of stem cell research
Cons of Stem Cell Research
  • Destroys human embryos
    • Early embryos are human beings
    • Many claim embryos aren't human beings
  • Government has banned stem cell research
    • Killing of embryos has been banned by U.S. government
    • Forced scientists to use alternatives, like amniotic fluid cells
  • Alternatives are useless
    • Dr. George Daley states that “The discovery shouldn’t be used as a replacement for human embryonic stem cell research
    • Amniotic cells can’t be used on humans
    • Waste of time and money
cons of stem cell research cont
Cons of Stem Cell Research (cont.)
  • Dangerous animal testing
    • Scientists test discoveries on animals
    • Most are human eggs and sperm, which can be harmful if animals mated
    • Animals could develop human brains, creating terrible results if animals mated
    • Kelly Olson says animal testing is inaccurate and ineffective
    • Animal testing totally pointless and worthless, waste of money and lives
stem cell research is it really worthless
Stem Cell Research-Is it Really Worthless?
  • Destruction of embryos may lead to disease cures, worth the sacrifice
  • Embryo destruction serves purpose
  • Embryos aren’t really human
    • 5 day old embryo invisible to human eye
    • No identifying features of nervous system
    • Can not survive outside of womb
    • Lack sentience
stem cell research is it really worthless cont
Stem Cell Research-Is it Really Worthless? (cont.)
  • New guidelines for research will persuade government to support research
  • Doesn’t waste money
    • Other nations putting money into research
  • Provides cures for other diseases
  • Alternatives aren’t as effective
  • Work well for other things
stem cell research is it really worthless cont10
Stem Cell Research-Is it Really Worthless? (cont.)
  • Scientists guide lining ethics for stem cell research
    • The Academy suggests setting local and national committees
    • Committees will set rules for stem cell research
  • Academy also suggests setting limits on animal testing
    • Chimeric animals should not be allowed to mate
    • Human stem cells should not be injected into non-human primates
  • Should not be grown for more than 14 days
    • Human nervous system recognizable after 14 days
  • Animal testing safer if guidelines applied
    • Animal stem cell research ensures safety of stem cell use on humans
why should it be continued
Why Should it be Continued?
  • Further world of medicine and science
    • Providing new cures for diseases
    • Providing way to test new drugs without human subjects
    • Other nations moving forward
    • U.S. needs to stay in the game to hold up as world power
why shouldn t it be continued
Why Shouldn’t it be Continued
  • Stem cell research is unethical and unpractical
    • Destroys potential human life
    • Government banned use of stem cell research
    • Risky animal testing involved
to be quite honest with you
To Be Quite Honest With You…
  • We all support stem cell research
  • Many benefits from stem cell research
  • Misuse could be disastrous
    • Care of scientists a necessity
