title: Blood cells need glia, too: a new role for the nervous system in the bone marrow niche.
abstract: Regulation of hematopoietic stem cell (HSC) dormancy by specific cell types in the hematopoietic niche remains poorly understood. Yamazaki et al. (2011) now report that nerve-associated nonmyelinating Schwann cells activate TGF-β to maintain dormant HSCs, suggesting that glia are novel players in the bone marrow niche.
