Classifications of stem cells

Classification	Stem cell types	Definition	Examples
Origin	Embryonic	Stem cells derived from the early stages of embryos	/
	Adult	Stem cells identified throughout the body that divide to replenish dying cells and regenerate damaged tissues
	Induced pluripotent	Stem cells derived from adult cells by being reprogrammed to embryonic stem cell-like states
Differentiation potential	Unipotent	Stem cells with the capacity to differentiate into only one specific cell type	Muscle satellite cells
	Oligopotent	Stem cells with the capacity to differentiate into only a few cell types	Lymphoid stem cells
	Multipotent	Stem cells with the capacity to differentiate into multiple cell types	Adult stem cells
	Pluripotent	Stem cells with the capacity to differentiate into nearly all cell types	Embryonic stem cells
	Totipotent	Stem cells with the capacity to differentiate into all cell types and a functional organism	Zygotes
