abstract = {The bone marrow is home to hematopoietic stem cells
responsible for lifelong blood production, alongside
mesenchymal stem cells required for skeletal regeneration.
In the bone marrow, a unique combination of signals derived
from a multitude of cell types results in the establishment
of so-called niches that regulate stem-cell maintenance and
differentiation. Recently, single-cell and spatially
resolved transcriptomics technologies have been utilized to
characterize the murine bone marrow microenvironment during
homeostasis, stress and upon cancer-induced remodeling. In
this review, we summarize the major findings of these
studies.Single-cell technologies applied to bone marrow
provided the first systematic and label-free identification
of bone marrow cell types, enabled their molecular and
spatial characterization, and clarified the cellular sources
of key prohematopoietic factors. Large transcriptional
heterogeneity and novel subpopulations were observed in
compartments previously thought to be homogenous. For
example, Lepr Cxcl12-abundant reticular cells were shown to
constitute the major source of prohematopoietic factors, but
consist of subpopulations differing in their adipogenic
versus osteogenic priming, morphology and localization.
These subpopulations were suggested to act as professional
cytokine secreting cells, thereby establishing distinct bone
marrow niches.Single-cell and spatially resolved
transcriptomics approaches have clarified the molecular
identity and localization of bone marrow-resident cell
types, paving the road for a deeper exploration of bone
marrow niches in the mouse and humans.},
