Military strategy commonly relies on holding a reserve force. In order to respond quickly to unforeseen situations or weaknesses, this tactical reserve is not initially committed to the conflict; it may also be called on to exploit opportunities against an opponent. Recent evidence has revealed that stem cell populations similarly maintain a reserve population. Reserved stem cells remain in a dormant, quiescent state until, in response to stress and aging, they serve to replenish and maintain, respectively, the stem cell pool. Unfortunately, cancer may also be maintained by an analogous reserved population that can replenish a neoplasm, especially following cytotoxic chemotherapy. Understanding the biology of reserved stem cells has important implications for stem cell therapy and cancer treatment. In this chapter, stem cell dormancy and quiescence – and its implications for normal stem cell biology and tumorigenesis – will be reviewed.
