abstract = {The bone marrow constitutes the primary site for life-long
blood production and skeletal regeneration. However, its
cellular and spatial organization remains controversial.
Here, we combine single-cell and spatially resolved
transcriptomics to systematically map the molecular,
cellular and spatial composition of distinct bone marrow
niches. This allowed us to transcriptionally profile all
major bone-marrow-resident cell types, determine their
localization and clarify sources of pro-haematopoietic
factors. Our data demonstrate that Cxcl12-abundant-reticular
(CAR) cell subsets (Adipo-CAR and Osteo-CAR) differentially
localize to sinusoidal and arteriolar surfaces, act locally
as 'professional cytokine-secreting cells' and thereby
establish peri-vascular micro-niches. Importantly, the
three-dimensional bone-marrow organization can be accurately
inferred from single-cell transcriptome data using the
RNA-Magnet algorithm described here. Together, our study
reveals the cellular and spatial organization of bone marrow
niches and offers a systematic approach to dissect the
complex organization of whole organs.},
