For many years, quiescence was viewed as a relatively unimportant state during which cells are inactive. We have only recently discovered that quiescent stem cells are like the proverbial still waters that run deep. Quiescence is a complex and highly regulated state that is critical to the long-term survival and availability of the stem cell populations our bodies rely on throughout our lives.
