  • Stem cells
    • 3 Types of Stem Cells
      • Embryonic stem cells
      • Umbilical Stem Cells
      • Adult Stem Cells
  • Derived from the undifferentiated inner cells of a human embryo - pluripotent: able to grow into any cell
  • Therapeutic Cloning
    • 1) Scientist extracts nucleus from egg
      • Nucleus holds genetic information
        • Somatic cells nucleus also extracted
          • Nucleus extracted from somatic cell inserted into egg
            • Egg contains new genetic material
  • Somatic cells nucleus also extracted
    • Nucleus extracted from somatic cell inserted into egg
      • Egg contains new genetic material
  • Stimulated to divide and forms cluster of cells
    • Disadvantages: Embryonic Stem cells may not be the solution for all ailments
      • Stem cell therapy: Use of stem cells to treat/prevent disease
        • Advantages: provides medical benefits in scientific fields
          • Potential treatment and cures for diseases such as diabetes, cancer, schizophrenia
            • Helps scientists learn about human growth and cell development
          • Improve quality of  life
      • Unknown long term effects
