Abstract Adult stem cells are maintained in a quiescent state but are able to exit quiescence and rapidly expand and differentiate in response to stress. The quiescent state appears to be necessary for preserving the self-renewal of stem cells and is a critical factor in the resistance of cancer stem cells (CSCs) to chemotherapy and targeted therapies. Limited knowledge about quiescence mechanisms has prevented significant advances in targeting of drug-resistant quiescent CSCs populations in the clinic. Thus, an improved understanding of the molecular mechanisms of quiescence in adult stem cells is critical for the development of molecularly targeted therapies against quiescent CSCs in different cancers. Recent studies have provided a better understanding of the intrinsic and extrinsic regulatory mechanisms that control stem cell quiescence. It is now appreciated that the p53 gene plays a critical role in regulating stem cell quiescence. Other intrinsic regulatory mechanisms include the FoxO, HIF-1α, and NFATc1 transcription factors and signaling through ATM and mTOR. Extrinsic microenvironmental regulatory mechanisms include angiopoietin-1, TGF-β, bone morphogenic protein, thrombopoietin, N-cadherin, and integrin adhesion receptors; Wnt/β-catenin signaling; and osteopontin. In this article, we review current advances in understanding normal stem cell quiescence, their significance for CSC quiescence and drug resistance, and the potential clinical applications of these findings. ©2011 AACR.
