title: This niche is a maze; an amazing niche.
abstract: The cellular identity of niche cells that regulate hematopoietic stem cell (HSC) self-renewal and differentiation has been debated for several years. Two recent studies in Nature (Ding and Morrison, 2013; Greenbaum et al., 2013) have shed light into the bone marrow stromal subsets making CXCL12, a chemokine critical for HSC maintenance.
