Classification and Characteristics of Stem Cells By Potency
By Origin
•
Totipotent Stem Cell - can give rise to an entire organism.
•
•
Pluripotent Stem Cell - can give rise to all tissues.
Embryonic Stem Cell - pluripotent, risen from the inner cell mass of a pre-implantation embryo.
•
Multipotent Stem Cell - can give rise to discrete cell types.
•
•
Embryonic Germ Cell - derived from primordial germline cells.
Oligopotent Stem Cell - can differentiate into a few different cell types.
•
•
Adult Stem Cell – multipotent, found in organs that need a constant supply of cells.
Unipotent Stem Cell - can only produce cells of one kind.
