Clonogenic progenitor cell capacity of subfractions isolated from CD34−CD38−Lin− and CD34+CD38−Lin−populations. CFC capacity was assessed in subfractions isolated from (A) CD34−CD38−Lin−cells and (B) CD34V+CD38−Lin− cells based on the absence or presence of CD7 and AC133 and represented as the number of CFCs per 1000 purified cells. Sorting gates used for isolation of subfractions are indicated in Figure 1 (A to E). Values are the mean and the SEM of determinations from up to 4 separate CB samples. Plating efficiencies were calculated by dividing the number of cells plated by the number of CFCs detected.
