stem cells

• • During the development of the embryos, most cells become specialised and can't be changed into another cell
  • Embryos have a specialised cell called stem cells
  • They can grow into any cell found in the body and are unspecialised (Stem cells are unspecialised but can become specialised - which they do)
• • Stem cells are used to repair cells and make healthy ones
  • The 2 types of stem cells are Embryonic and Adult
  • Unspecialised cells are called meristems
  • Embryonic and Adult cells are meristems
  • Embryonic stem cells can turn into any cell while Adult stem cells can only turn into some cells
• Therapeutic cloning uses cloned cells to make an embryo, removed embryonic stem cells are removed to grow tissues replaced in a human.
