Because uncontrolled cell division is so dangerous for an organism, cells must know not only when to divide, but?crucially?when not to. Cell division arrest prevents tumors and maintains the proper form of tissues. Many cells must also retain the ability to start dividing again when conditions are right, e.g., when the organism must grow, or a damaged tissue must be repaired. A cell in such a temporary, non-dividing state is said to be ?quiescent.? Quiescence is a common state for many somatic cells, including fibroblasts, lymphocytes, hematopoietic stem cells, and even dormant tumor cells. Failure to appropriately regulate the transition between quiescence and proliferation underlies several common and lethal disorders, including cancer and chronic wounds. My research is focused on understanding the molecular basis of quiescence using in vitro models, mouse models and human patients.
