Physiological stem cell function is regulated by secreted factors produced by
niche cells. In this study, we describe an unbiased approach based on the
differential single-cell gene expression analysis of mesenchymal osteolineage
cells close to, and further removed from, hematopoietic stem/progenitor cells
(HSPCs) to identify candidate niche factors. Mesenchymal cells displayed distinct
molecular profiles based on their relative location. We functionally examined,
among the genes that were preferentially expressed in proximal cells, three
secreted or cell-surface molecules not previously connected to HSPC biology-the
secreted RNase angiogenin, the cytokine IL18, and the adhesion molecule
Embigin-and discovered that all of these factors are HSPC quiescence regulators.
Therefore, our proximity-based differential single-cell approach reveals
molecular heterogeneity within niche cells and can be used to identify novel
extrinsic stem/progenitor cell regulators. Similar approaches could also be
applied to other stem cell/niche pairs to advance the understanding of
microenvironmental regulation of stem cell function.
