Unlike pluripotent stem cells, adult or multipotent stem cells in culture not only have a restricted array of cell types that they can create, but they also have a finite number of generations for self-renewal.

When a multipotent stem cell divides asymmetrically, its maturing daughter cell often goes through a transition stage as a progenitor or transit-amplifying cell, as is seen in the formation of blood cells, sperm, and neurons.

Progenitor cells are not capable of unlimited self-renewal; rather, they have the capacity to divide only a few times before differentiating.
