Deep diving in the blood stem cell-ome

Demetrios Kalaitzidis et al. EMBO J. .

Abstract

Defining the functional distinctions between cells comprising the bone marrow has yielded fundamental insights into lineage ordering and drivers of blood cell production. A novel, highly granular and multi-dimensional molecular characterization of functional subsets of hematopoietic stem- and progenitor cells recently published in Cell Stem Cell (Cabezas-Wallscheid et al, 2014) will serve as a landmark and treasure trove for unanticipated insights into basic biology and the development of future targeted medicine.

Figure 1. Application of global profiling methods for the study of HSC biology
Cabezas-Wallscheid et al (2014) performed multiple unbiased profiling methods (listed) on an HSC-enriched populations (HSC-EP) and 4 other distinct hematopoietic progenitor populations (HPC). They identified multiple pathways upregulated in HSC-EP, as well as provided a rich resource of multiple data types for stem-cell biology.
