The term progenitor cell is used in cell biology and developmental biology to refer to immature or undifferentiated cells, typically found in post-natal animals. While progenitor cells share many common features with stem cells, the term is far less restrictive.
Like stem cells, progenitor cells have a capacity for self-renewal and differentiation, although these properties may be limited.
Stem cells: Unlimited self-renewal and are pluripotent.
Progenitor cells: Self-renewal can be limited and are unipotent or multipotent.
