Concept essentials

  • Totipotent cells have the broadest developmental potential.
  • Pluripotent cells can form many body cell types but not all extra-embryonic tissues.
  • Multipotent adult stem cells form a restricted set of related cell types.
  • Differentiated cells such as neurons have much less developmental potential than stem cells.
