Patients with newly diagnosed AML received intravenously IdUrd. After the rhodamine efflux assay, 25% of the most RhoD and RhoB leukemic blasts were sorted. The sorted subfractions were stained and the IdUrd LI could be calculated. PI was used to measure DNA content. Percent S/G2+M and the IdUrd of the RhoD cells was significantly lower (P = .008 and P = .001, respectively) compared with the RhoB cells.
