Survival of F and non-F cells.

♦, F cells; ▵, non-F cells. For the panels on the left, the survival for each cell type was derived from the overall survival, the percentage of HbF in the magnetically isolated labeled cells, and the HbF per F cell for each patient. For the panels on the right, the overall survival and the flow cytometric quantitation of the percentage of labeled F cells were used in a similar manner. Formulas and sample calculations are given in Franco et al.10
