  • Process of micropropagation to clone plants-
    Cut a small piece of plant tissue, an explant, from the tips of stems, and sterilise them to remove microorganisms. Place the explants in a petri dish that contains agar jelly with growth hormones and nutrients like glucose and mineral ions. Once they grow a bit into calluses, transfer them to soil so they can grow into plantlets. Finally transfer them to their own pot. Ensure that the whole process is done at a reasonable temperature and that the plants get enough light and water.
  • Adult stem cell transplants
    Could use a patient's own stem cells or be from a donor
  • Stem cells from patient's own cells
    • Genetically identical
    • Not rejected by patient's immune system
  • Stem cells from donor
    • Not genetically identical
    • Fewer complications if from close family member
    • Could come from person with closely-matched tissue types
  • Therapeutic cloning
    Transfer nucleus from patient's cell to egg cell with nucleus removed
  • Therapeutic cloning
    Could produce stem cells with same genetic make-up as patient
