title: Nervous activity in a stem cell niche.
abstract: In this issue of Cell, report a new regulatory axis for the mobilization of hematopoietic stem cells that links these cells to the nervous system and bone in an unanticipated way. The new findings suggest that the nervous system, which has the inherent ability to integrate information from throughout the organism, may govern the local relationship between stem cells and their niches.
