General Information

Term

stem cell population maintenance

ID (Ontology)

GO:0019827 (Gene Ontology)

Definition

The process by which an organism or tissue maintains a population of stem cells of a single type. This can be achieved by a number of mechanisms: stem cell asymmetric division maintains stem cell numbers; stem cell symmetric division increases them; maintenance of a stem cell niche maintains the conditions for commitment to the stem cell fate for some types of stem cell; stem cells may arise de novo from other cell types.[ ISBN:0878932437 ]
