Stem Cells

• Undifferentiated cells are stem cells.
• Embryonic Stems stells can turn into ANY type of cell.
• Adult stem cells are found in the bone marrow, whereas embryonic cells are found in the embyro.
• Adult stem cells can only turn into certain cells.
• adult stem cells cure diseases for example, replacing faulty blood cells.
• THERAPUTIC CLONING = embryo is used because it has the same genetic info as patient. So, it wont be rejected by the body.
• Disadvantages of Theraputic Cloning

  
  

  • Stem cells in lab can become contaminated with a virus which can be passed down to patient.
• Against Stem Cells

  
  

  • Some people believe the embryos couldve been potential human life
  • Some are discarded.
• In Plants, stems cells are found in Meristems
• Name a medical condition that stem cells could treat?

  
  

  • Diabetes by producing insulin-producing cells
• Benefits of clonning plants

  
  

  • They are gentically identical
  • Prevent extinction of plants
  • It is cheap and quick
• THERAPEUTIC CLONING

  
  

  • Nucleus removed from egg cell
  • Nucleus removed from body cell
  • Body cell nucleus fuse with empty egg cell
  • Produce Embryo
  • Form Stem cells
