Stem Cells

• What do Stem Cells hold the possibility to do?


  Divide to produce lots more undifferentiated cells.
• Where are stem cells found?


  Human Embryos.
• What can Stem cells turn into?


  Ant kind of cell at all.
• Where are adult Stem cells found?


  Bone Marrow.
• What’s the difference between Stem cells in adults and embryos?


  Adult ones cannot turn into any cell.
• What can Adult Stem Cells differentiate into?


  blood cells.
• What can Adult and Embryonic stem cells do?


  produce genetically identical clones.
• What can the specialised cells be used in?


  Medicine or research.
• What are Adult stem cells used for in medicine?


  To cure disease.
• What can stem cells from the bone marrow of a healthy person do for a sick person?


  Replace faulty blood cells.
• What are examples of specialised adult stem cells in medicine?


  Insulin producing cells

  nerve cells
• What types of people can Insulin producing cells help?


  People with Diabetes
• What type of people can Nerve cells help?


  people paralysed by spinal injuries.
• What is Therapeutic cloning?


  When an embryo is made to have the same genetic information as a patient.
• What does therapeutic cloning ensure? Why?


  The stems cells produced contain the same genes, so they wouldn’t be rejected by the patients body.
• What are risks of using stem cells in medicine?


  Stem cells grown in labs could be contaminated with a virus and passed on to a patient and make them sicker.
• Why are some people against Stem Cells?


  They believe embryos shouldn’t be used as they’re potentially a human life.
• Where are stem cells found in Plants?


  In the meristems
• When can the meristem differentiate in a plants life cycle?


  Throughout the plants entire life.
• What can the Stems cells be used for in plants?


  To produce clones quickly and cheap.

  To grow more plants of rare species to prevent extinction

  To grow crops of identical plants to help farmers. eg. Disease resistance.
