Abstract: Controlling fates of stem and progenitor cells is one of the central goals of regenerative medicine. However, conventional cell enumeration methods are unable to distinguish between the effects of cell death, proliferation, and differentiation through molecular interventions on the output of specific cell types. We have devised a strategy to simultaneously obtain proliferation and death rates in cultures of highly purified erythroid progenitors. The approach is based on combining cell-surface marker analysis, cell-division tracking and 7-amino-actinomycin-D staining to monitor cell death. A compartment model of cell proliferation was developed to evaluate cell generation-specific length of cell-division, rates of entry into division, and cell death, from the experimental cell-division tracking data obtained following stimulation with erythropoietin (EPO) and Stem cell factor (SCF). The results indicated that EPO and SCF, either as single factor or in combination, differentially affect the rates of differentiation, length of cell-division and rates of death.
