Time to wake up: regulation of stem cell quiescence and proliferation
Stem cell populations in tissues as varied as blood, gut and brain spend much of their time in a mitotically dormant, quiescent, state. A key point of regulation is the decision between quiescence and proliferation. The ability to reactivate neural stem cells in situ raises the prospect of potential future therapies for brain repair after damage or neurodegenerative disease. Understanding the molecular basis for stem cell reactivation is an essential first step in this quest.
