Integration of mechanical and ECM microenvironment signals in the determination of cancer stem cell states.
Purpose of review: Cancer stem cells (CSCs) are increasingly understood to play a central role in tumor progression. Growing evidence implicates tumor microenvironments as a source of signals that regulate or even impose CSC states on tumor cells. This review explores points of integration for microenvironment-derived signals that are thought to regulate CSCs in carcinomas.
Recent findings: CSC states are directly regulated by the mechanical properties and extra cellular matrix (ECM) composition of tumor microenvironments that promote CSC growth and survival, which may explain some modes of therapeutic resistance. CSCs sense mechanical forces and ECM composition through integrins and other cell surface receptors, which then activate a number of intracellular signaling pathways. The relevant signaling events are dynamic and context-dependent.
Summary: CSCs are thought to drive cancer metastases and therapeutic resistance. Cells that are in CSC states and more differentiated states appear to be reversible and conditional upon the components of the tumor microenvironment. Signals imposed by tumor microenvironment are of a combinatorial nature, ultimately representing the integration of multiple physical and chemical signals. Comprehensive understanding of the tumor microenvironment-imposed signaling that maintains cells in CSC states may guide future therapeutic interventions.
期刊介绍:
The goal of this journal is to publish cutting-edge reviews on subjects pertinent to all aspects of stem cell research, therapy, ethics, commercialization, and policy. We aim to provide incisive, insightful, and balanced contributions from leading experts in each relevant domain that will be of immediate interest to a wide readership of clinicians, basic scientists, and translational investigators.
We accomplish this aim by appointing major authorities to serve as Section Editors in key subject areas across the discipline. Section Editors select topics to be reviewed by leading experts who emphasize recent developments and highlight important papers published over the past year on their topics, in a crisp and readable format. We also provide commentaries from well-known figures in the field, and an Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research.
