    In this video, we look at what is meant by stem cells. We then look at the uses of stem cells in medicine. Finally, we explore stem cells in plants and how these can be useful.
    This video is based on the AQA spec. If you are following a different exam board then you should check your specification. The Amazon link above is an affiliate link.

      the reason for therapeutic cloning is to make the same stem cells as the subject,
      therefore, if the "parents don't want to child", there wouldn't be a reason for therapeutic cloning
      therapeutic cloning is creating an identical stem cell copy of your own cell

    • @user-ic7rj2gv2z
      @user-ic7rj2gv2z 3 роки тому +1

      the difference is that embryonic stem cells can change into any type of cells, while regular stem cells will only be able to change into limited types of stem cells. (of course, this is only in humans)
      also, embryonic stem cells can only be found in the embryo stage while stem cells such as the bone marrow stem cell can be found anytime
