Stem cell potential refers to the range of cell types a stem cell can produce.
#Id: 932
A totipotent stem cell can generate all cell types of both embryonic and extraembryonic lineages.
#Id: 933
The niche employs a variety of mechanisms of cell-to-cell communication to regulate the quiescent, proliferative, and differentiative states of the resident stem cell.
#Id: 934
The shoot apical and root apical meristems provide a continuous source of totipotent stem cells for a plant to generate a majority of its aerial and ground tissues throughout life.
#Id: 935
When a multipotent stem cell divides asymmetrically, its maturing daughter cell often goes through a transition stage as a progenitor or transit-amplifying cell.

Precursor cell (or simply precursors), is widely used to denote any ancestral cell type (either stem cell or progenitor cell) of a particular lineage.
