Totipotent Stem Cells - They can differentiate into any type of human body cell or the placenta.
Example: Fertilized egg cells.
Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.
Example: Blastocyst cells.
Multipotent Stem Cells - They can only differentiate into closely related cells.
Example: Blood stem cell
Unipotent Stem Cells - They can only produce their type of cell.
Example: Skin stem cells (which can only become a new skin stem cell).
