Figure 1. Models of bone marrow hematopoiesis. The current model of blood formation is a continuous process of the differentiation and progressive loss of stem cell features (quiescence, self-renewal, and multipotency).

Figure 2. Control of HSC quiescence. (A) HSC quiescence is controlled by stem cell extrinsic (SCE) and intrinsic (SCI) factors. Proliferating HSCs face multiple fates: differentiation, mobilization, death, senescence, and re-entry to quiescence. (B) Regulation of the exit from quiescence and entry into cell division by cell cycle regulators (activating in green and inhibitory in red).

Figure 3. G0S2 promotes quiescence by interacting with nucleolin. (A) The arginine-glycine-glycine (RGG) domain of nucleolin interacts with a highly conserved hydrophobic domain (HD) of G0S2. (B) The ectopic expression of G0S2 retains nucleolin in the cytosol of quiescent HSCs (Lin− Sca-1+ c-kit+ CD48− CD150+ cells). (C) Diagram depicting a novel model that controls the quiescence of HSCs mediated by the interaction between G0S2 and nucleolin.
