Abstract:
:Hematopoiesis requires tight regulation of the hematopoietic stem cell (HSC) population; however, the dynamics of HSC use at steady state are uncertain. Over 3-7 months, we evaluated the repopulation and self-renewal of more than 600 individual human 'severe combined immunodeficiency mouse-repopulating cells' (SRCs), tracked on the basis of lentiviral integration sites, in serially transplanted immune-deficient mice, as well as of SRC daughter cells that migrated to different marrow locations in a single mouse. Our data demonstrate maintenance by self-renewing SRCs after an initial period of clonal instability, a result inconsistent with the clonal succession model. We found wide variation in proliferation kinetics and self-renewal among SRCs, as well as between SRC daughter cells that repopulated equivalently, suggesting that SRC fate is unpredictable before SRCs enter more rigid 'downstream' developmental programs.
