    Answer:

There are three classes of stem cells: totipotent, multipotent, and pluripotent.

  • A fertilized egg is considered totipotent, meaning that its potential is total; it gives rise to all the different types of cells in the body.
  • Stem cells that can give rise to a small number of different cell types are generally called multipotent.
  • Pluripotent stem cells can give rise to any type of cell in the body except those needed to develop a fetus.
