Blood Development: Hematopoietic Stem Cell Dependence and Independence

Publication date: 3 May 2018
Source:Cell Stem Cell, Volume 22, Issue 5
Author(s): Elaine Dzierzak, Anna Bigas
Evidence of the diversity and multi-layered organization of the hematopoietic system is leading to new insights that may inform ex vivo production of blood cells. Interestingly, not all long-lived hematopoietic cells derive from hematopoietic stem cells (HSCs). Here we review the current knowledge on HSC-dependent cell lineages and HSC-independent tissue-resident hematopoietic cells and how they arise during embryonic development. Classical embryological and genetic experiments, cell fate tracing data, single-cell imaging, and transcriptomics studies provide information on the molecular/cell trajectories that form the complete hematopoietic system. We also discuss the current developmentally informed efforts toward generating engraftable and multilineage blood cells.

Dzierzak and Bigas review the current knowledge on molecular/cell trajectories that generate the complete hematopoietic system, informed by classical embryological and genetic experiments, cell fate tracing data, single-cell imaging, and transcriptomics studies. The authors also discuss the current developmentally informed efforts toward generating engraftable and multilineage blood cells.
